Staged scleroobliteration in the complex treatment of varicose veins of the lower extremities in the elderly

Annotation. Varicose veins of the lower extremities tend to be more common in older age groups, whose treatment is complicated by comorbidity and advanced pathology. The aim is to develop an effective, safe and economical method of treating varicose veins of the lower extremities in elderly and senile patients. We monitored 69 patients who underwent scleroobliteration and compression therapy. The first group – 31 patients aged 67-83 years with pronounced comorbidity, limited mobility and difficulties with the use of compression knitwear. The aescinic salt of 2,6-diaminohexanoic acid was used in the form of a 0.1% solution. After the session, an elastic bandage, a compression product of 15–20 mm Hg, or a combination thereof was applied to the lower leg. The patients followed the movement regime available to them. The second group – 38 patients aged 23-51 years. Lauromacrogol 400 (polidocanol) was used in the form of a foam form of a 3% solution. After the session, a compression product of 23-32 mm Hg was used. Statistical methods of processing: Student’s test and Fisher's angle transformer. It was found that course of the scleroobliteration session (character, duration and intensity of pain), early (sensation along the course of sclerosed veins, their nature, intensity and duration) and long-term (disappearance or degree of reduction of varicose veins, tissue condition in the area of sclerosed veins, frequency of recanalization) periods after scleroobliteration in patients of both groups was identical. In 16 patients of the 1st group, compression was performed for less time and not in full. Among them, thrombophlebitis occurred in one patient. Among the patients of the II group, compression defects were observed in 3 cases. Two of them developed thrombophlebitis (p<0.01). So staged scleroobliteration in the complex treatment of varicose veins of the lower extremities is an effective, safe, low-traumatic, simple, economical outpatient technology. Aescinic salt of 2,6-diaminohexanoic acid should be considered the drug of choice for scleroobliteration in elderly patients with limited mobility.

Safety assessment of cyanoacrylate closure for treatment of varicose veins in a large-scale national survey in Japan.

Cyanoacrylate closure (CAC) is a minimally invasive technique for treating axial venous reflux. However, the incidence of serious adverse events (AEs) related to CAC is concerning. With an increasing number of patients undergoing CAC and insufficient safety data in Japan, this study aimed to investigate the safety profile of CAC, focusing on the types and incidence of AEs. A nationwide survey was conducted by the Japanese Regulatory Committee for Endovascular Treatment of Varicose Veins between November 2023 and December 2023. Data were collected from 1017 institutions, covering 24,209 patients who underwent CAC at 335 institutions between January 2020 and October 2023. Thromboembolism, phlebitis, hypersensitivity reactions, granuloma formation, infection, bleeding, death, and need for glue resection were documented as unfavorable events or outcomes. Venous thromboembolism developed in 142 patients (0.59%). Pulmonary embolism, proximal deep vein thrombosis, and ablation-related thrombus extension developed in 3 (0.01%), 9 (0.04%), and 95 (0.39%) patients, respectively. Localized phlebitis that required additional treatment was observed in 1656 patients (6.8%). Of the localized hypersensitivity cases, 960 (58%) required oral antihistamines and 268 (16%) required oral and/or intravenous steroids. Furthermore, 65 patients (0.27%) developed systemic hypersensitivity that required systemic steroids. No patients developed a stroke or anaphylaxis. One patient died owing to pulmonary embolism. Glue resection was performed in nine patients with delayed infection (n= 4), hypersensitivity reactions (n= 4), or a foreign body granuloma (n= 1). The incidence of hypersensitivity reactions was similar among institutions. However, the incidence of thrombosis-related events significantly differed between the high-volume and low-volume institutions. The incidence of proximal deep vein thrombosis (0.13% vs 0.01%; P< .001; odds ratio, 12.5; 95% confidence interval, 2.6-60.3) and ablation-related thrombus extension (0.73% vs 0.30%; P< .001; odds ratio, 2.5; 95% confidence interval, 1.66-3.77) was significantly higher in low-volume institutions than in high-volume centers. A nationwide survey of CAC for varicose veins in Japan demonstrated that it was a safe procedure with a low rate of serious AEs, such as venous thromboembolism. However, hypersensitivity reactions requiring steroid administration and systemic allergic reactions were observed in some patients.

Predicting lack of clinical improvement following varicose vein ablation using machine learning.

Varicose vein ablation is generally indicated in patients with active/healed venous ulcers. However, patient selection for intervention in individuals without venous ulcers is less clear. Tools that predict lack of clinical improvement (LCI) following vein ablation may help guide clinical decision-making but remain limited. We developed machine learning (ML) algorithms that predict 1-year LCI following varicose vein ablation. The Vascular Quality Initiative (VQI) database was used to identify patients who underwent endovenous or surgical varicose vein treatment for Clinical-Etiological-Anatomical-Pathophysiological (CEAP) C2-C4 disease between 2014-2024. We identified 226 predictive features (111 pre-operative [demographic/clinical], 100 intra-operative [procedural], and 15 post-operative [immediate post-operative course/complications]). The primary outcome was 1-year LCI, defined as a pre-operative venous clinical severity score (VCSS) minus post-operative VCSS ≤ 0, indicating no clinical improvement following vein ablation. The data was divided into training (70%) and test (30%) sets. Six ML models were trained using pre-operative features with 10-fold cross-validation (Extreme Gradient Boosting [XGBoost], random forest, Naïve Bayes classifier, support vector machine, artificial neural network, and logistic regression). The primary model evaluation metric was area under the receiver operating characteristic curve (AUROC). The algorithm with the best performance was further trained using intra- and post-operative features. The focus was on pre-operative features, while intra- and post-operative features were of secondary importance, because pre-operative predictions offer the most potential to mitigate risk, such as deciding whether to proceed with intervention. Model calibration was assessed using calibration plots, while the accuracy of probabilistic predictions was evaluated with Brier scores. Performance was evaluated across subgroups based on age, sex, race, ethnicity, rurality, median Area Deprivation Index, prior ipsilateral varicose vein ablation, location of primary vein treated, and treatment type. Overall, 33,924 patients underwent varicose vein treatment (30,602 [90.2%] endovenous and 3,322 [9.8%] surgical) during the study period and 5,619 (16.6%) experienced 1-year LCI. Patients who developed the primary outcome were older, more likely to be socioeconomically disadvantaged, and less likely to routinely use compression therapy. They also had less severe disease as characterized by lower pre-operative VCSS, VVSymQ scores, and CEAP classifications. The best pre-operative prediction model was XGBoost, achieving an AUROC (95% CI) of 0.94 (0.93-0.95). In comparison, logistic regression had an AUROC (95% CI) of 0.71 (0.70-0.73). The XGBoost model had marginally improved performance at the intra- and post-operative stages, both achieving an AUROC (95% CI) of 0.97 (0.96-0.98). Calibration plots showed good agreement between predicted and observed event probabilities with Brier scores of 0.12 (pre-operative), 0.11 (intra-operative), and 0.10 (post-operative). Of the top 10 predictors, 7 were pre-operative features including VCSS, VVSymQ score, CEAP classification, prior varicose vein ablation, thrombus in the greater saphenous vein, and reflux in the deep veins. Model performance remained robust across all subgroups. We developed ML models that can accurately predict outcomes following endovenous and surgical varicose vein treatment for CEAP C2-C4 disease, performing better than logistic regression. These algorithms have potential for important utility in guiding patient counseling and peri-operative risk mitigation strategies to prevent LCI following varicose vein ablation.

Case report of varicose veins treatment in patient with a prosthetic mitral valve

This clinical case may be of interest in situations where a patient with varicose veins of the lower limbs and concomitant heart disease, who is on long-term anticoagulant therapy and is scheduled to undergo minor surgery, may present the possibility of endovenous laser ablation (EVLA) against the background of warfarin use. Patient, G., 68 years old, with rheumatic combined mitral valve disease (mitral valve replacement in 2019, permanent atrial fibrillation), also had varicose vein disease of the lower limbs. History included acute cerebrovascular accident (19.01.2023). Duplex Ultrasonography Screening (DUS) showed failure of the left great saphenous vein valve. Hypocoagulation was also observed in coagulogram and the risk of bleeding on HAS-BLED score was average. On Caprini score, the risk was very high. Endovenous laser ablation of the large saphenous vein on the left side was performed. During follow-up examinations, there were no signs of bleeding from puncture sites. The target trunk was obliterated in dynamics at DUS. Therefore, it is possible to carry out EVLA of a large subcutaneous vein while taking therapeutic doses of warfarin without switching to bridge therapy. Endovascular laser ablation allowed it to be done with less risk of bleeding and, against the background of taking warfarin, reduced the risk of thrombosis.

Steam Vein Sclerosis for Nonsaphenous varicose veins.

The treatment of nonsaphenous varicose veins (NSVV), including incompetent perforating veins (IPV) and recurrent varicose veins (RVV), remains challenging for many reasons, including vein tortuosity, deep location and short vein to be treated. Data and recommendations are lacking. Steam vein sclerosis (SVS) is an endothermal therapy that has been used in the treatment of incompetent saphenous veins, achieving occlusion rates similar to other thermal ablation techniques with good patient tolerance and minimal postoperative pain. We report here the results of a cohort of SVS used to treat NSVV, including RVV and IPV. From October 2017 to March 2020, consecutive patients presenting with NSVV treated with SVS were included. Patients were followed at 3months with both clinical and duplex scan examinations. The primary endpoint was efficacy defined as target vein occlusion at 3months; secondary endpoints were: safety with analysis of per procedural and 3months complications, evolution of functional stage and symptoms between inclusion and 3months. Ninety-six patients were included in the study. Five patients were lost to follow-up. Fifty-nine percent (n=60) were women. Lesions were recurrent (recurrent varicose vein after surgery) in 61% (n=62). The location of the NSVV was sapheno-femoral residual stump in 8% (n=8), inguinal neovascularization in 14% (n=14), sapheno-popliteal residual stump in 12% (n=12), popliteal neovascularization in 7% (n=7), and IPV in 59% (n=60). Complete occlusion after treatment occurred in 86% (n=83) of patients, partial occlusion in 4% (n=4), and complete recanalization in 10% (n=9). The occlusion rate in the IPV group was 93%. Complications at 30days postoperatively were 2 (2%) deep vein thrombosis, 1 (1%) hematoma, and 2 (2%) late paresthesias in the superficial peroneal nerve area. The use of SVS has been shown to be effective and safe in the short-term treatment of NSVV, including IPV and RVV. Further studies are needed to evaluate its long-term effects.

Technique and early results of endovenous laser ablation in morphologically complex varicose vein recurrence after small saphenous vein surgery.

Recurrences after varicose vein treatment occur frequently and represent a significant health and economic problem. In contrast to primary treatments of superficial truncal venous insufficiency, their management is often more difficult. Here we assessed the technical feasibility and early results of endovenous laser ablation (EVLA) for recurrences with stumps or subfascial meandering varices after small saphenous vein (SSV) surgery. This single-center retrospective study included 45 consecutive EVLA procedures from July 2019 to December 2021 in 40 patients (19 male, 21 female, mean age 62.8 ± 12.7 years). Patients had clinically relevant recurrent varicose veins after SSV surgery, with clinical, etiologic, anatomic and pathophysiologic (CEAP) classification stage of C2S or higher. We categorized the recurrences morphologically according to duplex sonographic criteria. Ablations were done with a 1470 nanometers laser and dual ring radial fibers and aimed at thermal closure as proximal as possible to the upper inflow. Analyses were performed by descriptive statistics and the Kaplan-Meier method. The primary outcome analyzed was the technical success, defined by thermal occlusion not requiring re-intervention during the observation period. The secondary outcome was the occurrence of postoperative complications. A complex morphology with residual stumps or tortuous venous connections to the popliteal vein was present in 35 cases (77.8%). Immediate technical success at the first postoperative visit after a median of 11 days (interquartile range 8-13 days) was 97.8%. During the follow-up period (median 77 days, interquartile range 13-256 days), 6 limbs (13.3%) required redo EVLA due to symptomatic persistent or newly presenting reflux. The median freedom from re-recurrence was 791 days. Otherwise, no medical or surgical complications requiring specific treatment were observed, particularly no endothermal heat-induced thrombosis (EHIT) or other thrombotic complications, and no nerve damage. According to our pilot data, EVLA is technically feasible for complex popliteal variceal recurrence, although the success rate appears substantially lower than for primary treatment of truncal venous insufficiency.

Hemodynamic surgery of varicose veins of the lower extremities with the introduction of modern technologies

Minimaly invasive and pathogenetically based methods are currently prevalent in phlebology, as they are in other fields of surgery. CHIVA (Сure conservatrice et hemodynamiу que de l’insuffisance veineuse en ambulatoire) hemodynamic surgery is one of these popular minimally invasive surgical procedures. The execution technique relies on the findings of a duplex ultrasound scan that is used to analyse the hemodynamics of the superficial venous network. The CHIVA strategy aims to preserve the venous material while also restoring normal distal venous pressure and venous function. However, this technique has a number of disadvantages, including the possibility of vein recanalisation and relapses, as well as the fact that the immediate cosmetic outcome is not always satisfactory. Objective — to compare the outcomes of lower extremity varicose vein treatment based on the employed method: the CHIVA method executed via open surgery versus the CHIVA method combined with other minimally invasive methods (sclerotherapy, endovenous laser coagulation (EVLC)). Materials and methods. A randomised prospective study was conducted on 52 patients with varicose veins of the lower extremities categorised as C1‑C3 according to the CEAR classification. The patients were divided into 2 groups of 26 patients each, with one group undergoing the CHIVA procedure using the classic open technique, and the other group receiving a combination of CHIVA with EVLC and sclerotherapy. To evaluate the results, we used Hobb’s criteria, measured the diameter of the great saphenous vein via ultrasound, analysed alterations in the Venous Clinical Severity Scoring (VCSS) , studied data from the Chronic Venous Insufficiency Quality of Life Questionnaire (CIVIQ 20), and determined the incidence of relapses. Results. After CHIVA and CHIVA + EVLC + sclerotherapy, the normalisation of hemodynamics and interruption of the venous shunt led to a substantial reduction in the diameter of the great saphenous vein within 6 months after the operation (p&lt;0.01). Both groups had an improvement in VCSS 6 months after surgery. No statistical difference was observed between the treatment groups. All methods had a positive impact on the quality of life of patients, as shown by the CIVIQ 20 questionnaire. Of the 52 operated patients, there were 4 relapses (7.7%). No relapses were noted in the group receiving CHIVA with EVLC and sclerotherapy (p=0.039). As evaluated by Hobb’s criteria, patients exhibited greater satisfaction with the outcomes of hemodynamic surgery combined with EVLC and sclerotherapy due to its better and faster aesthetic outcomes (р=0.012 and 0.05). Conclusions. All 52 patients exhibited favourable treatment outcomes, demonstrating a reduction in CVI symptoms during a comprehensive clinical assessment using ultrasound within 6 months and 1 year. The combination of CHIVA with EVLC and sclerotherapy showed distinct advantages in the treatment of varicose veins, yielding the most favourable cosmetic outcomes according to Hobb’s criteria and achieving a reccurence rate of 0%.

Hypothesis: Pump shoes for the prevention and treatment of varicose veins.

This hypothesis introduces pump shoes as a method for the prevention and treatment of varicose veins. An air pump is placed in the shoe, connected to an airbag wrapped around the leg through a hose. With each step, air is pumped into the foot airbag, applying pressure to the leg muscles and superficial veins. This action mimics muscle pumping, helping to push blood back towards the heart. Excess air is released through an outlet hose with an adjustable sphincter, allowing for increased pressure on the leg. These shoes offer a simple mechanism to assist in returning blood from the feet to the heart. They can be beneficial in preventing varicose veins in at-risk individuals or treating those in the early stages of the disease.

Etiological factors causing varicose veins and its advanced stratgical treatment for curing varicose veins

The purpose of this study was to evaluate the varicose vein treatment options available today. Numerous techniques exist for managing varicose veins. Treatment for varicose veins yields varying results. Compared to endovenous laser ablation and surgical stripping, foam sclerotherapy and radiofrequency ablation were linked to reduced discomfort and quicker recovery times. When compared to patients undergoing conventional high ligation and stripping, patients receiving endovenous laser ablation and radiofrequency ablation are likely to heal more quickly and return to work sooner. It is necessary to conduct a randomised controlled trial across several sites to determine which method is most effective for treating varicose veins.

ASSESSMENT OF PATIENTS' KNOWLEDGE REGARDING VARICOSE VEINS DISEASE

This study aims to present a complete epidemiological overview of the knowledge of patients about varicose vein disease in the city of Vlore. The study summarized all cases diagnosed by the angiologist, identifying risk factors, different age groups, surgical intervention, complications, and progress of these patients. In this cross-sectional study, we included 600 patients diagnosed with varicose veins. The patients participating in the study completed a questionnaire with questions divided into several sections. The first part belonged to questions about demographic data; the second part was related to the recognition of risk factors by sick patients; and finally, there was a section of questions related to surgical intervention for varicose veins. Regarding the age group, it turned out that patients with varicose veins belong to different age groups. 2.7% of patients belonged to the age group of 20–24 years. The age group of 61–65 years old made up 8.3% of the sample, and 6.5% were those patients in the age group over 65 years old. 32.5% of the sample belonged to the male gender, and 67.5% belonged to the female gender. Regarding hereditary as a risk factor, 4.17% of those who do not consider heredity an important factor belong to the age group of 56–60 years. There are only 30.8% of patients who stated that they underwent a surgical intervention. 69.2% have not done such a thing. The patients with varicose veins were of different age groups. According to the patient's point of view, there are several main factors that could cause the disease of varicose veins. Among the most important factors, it is worth mentioning heredity, hypertension, and pregnancy. Regarding the consequences caused by the disease of varicose veins, patients have clearly stated that phlebitis is an inflammation that occurs frequently. Since surgical intervention is considered an effective solution to treat vein disease, some patients have undergone surgery. Those patients who underwent surgery have been diagnosed with this disease for more than a year and belong to the age group of 56–60 years.

Progress and Current Status of Treatment for Lower Limb Varicose Veins

Varicose veins of lower extremities are common venous diseases of lower extremities in clinic [1]. The total number of patients with varicose veins of lower extremities in China has exceeded 100 million, and the incidence rate is about 15% [2]. Therefore, there is a huge number of illnesses and a demand for surgical treatment. At present, the main treatment options for lower limb varicose veins include conservative treatment and surgical treatment. Surgical treatment methods include traditional surgery and minimally invasive surgery. The high ligation and stripping of the great saphenous vein has always been the gold standard for the treatment of lower limb varicose veins. This method is technically mature and clinically effective, but it is a destructive surgery that uses a stripping device to forcefully pull. Therefore, the intraoperative trauma is large, the amount of bleeding is high, and a series of postoperative complications such as hidden nerve damage, subcutaneous congestion, incision bleeding, deep vein thrombosis, etc. are prone to occur. With the increasing demand for skin aesthetics and reducing postoperative complications, minimally invasive surgery has gradually been applied to the treatment of lower limb varicose veins, such as intracavitary laser ablation, intracavitary radiofrequency ablation, Tri Vex minimally invasive rotary cutting, hemodynamic correction, etc. [3]. This article provides a review of the current main treatment methods for lower limb varicose veins, in order to further understand and master the principles and application scope of each treatment method, and to better select personalized treatment plans for varicose vein patients in the future.

First registry of patients treated with foam sclerotherapy using a new automated microfoam preparation device (2021-2022).

Objectives: To present results for the use of an automated microfoam preparation system (AMPS) in the treatment of varicose veins in a real-world setting.Method: We performed a descriptive study based on a prospective database of patients treated with foam sclerotherapy between February 2021 and December 2022. Polidocanol foam was prepared using a capsule containing sterile air or a low-nitrogen mix. We recorded volume per session, percentage of sclerosing drug, number of sessions, release of thrombus entrapment, complications, and adverse events. A univariate descriptive analysis was performed using Stata V.16.Results: Over a 23-month period, 185 patients (84.9% women, 15.1% men) underwent 685 sessions. Median age was 51.6 years (range, 16-79 years). Thread veins were the condition treated in 68.9% of sessions, tributaries in 7.2%, and truncal veins in 22.6%. The average volume per session was as follows: thread veins, 8mL; great saphenous vein (GSV), 6.9mL; and small saphenous vein (SSV), 4.3mL. The average drug concentration was as follows: thread veins, 0.18%; GSV, 1.49%; and SSV, 1.63%. The average number of sessions was 3.4 for thread veins, 2 for tributaries, 2.7 for the GSV, and 2.9 for the SSV. The occlusion rate at 15 months was 93.2% (41/43) for the great saphenous vein and 86% (13/15) for the small saphenous vein. We recorded a total of 21 complications (3.1% of sessions), 14 of which were minor complications (2% sessions), and 7 moderate adverse events (1% of sessions).Conclusions: This new device is highly versatile and can be used for preparing foam at all concentrations. It contributes to a high rate of occlusion in saphenous trunks, with a minimal number of sessions required for thread veins indicating that the system is a favorable option in the treatment of venous diseases. Additionally, the low frequency of residual pigmentation may be attributed to the system's ability to tailor the foam concentration to the individual case, thus supporting optimal outcomes.

Therapeutic Potential of Molsidomine-Loaded Liquid Crystal Nanoparticles for the Treatment and Management of Niacin-Induced Varicose Veins: In Vitro and In Vivo Studies.

Varicose vein therapy has historically relied significantly on invasive surgical procedures, which frequently resulted in poor compliance among patients. The tendency could stem from the past use of abrasive surgical procedures and a lack of documented drug-induced animal models. To address this challenge, we envisaged an innovative approach for animal model development that uses niacin-induced recurrent flushing. And to further treat the condition, we used liquid crystal nanoparticles (LCNPs) as carriers for the antiangiogenic, cardio protective, and anti-inflammatory drug molsidomine. After the successful initiation of reticular perforant varicose veins, the animals were administered and treated with molsidomine-loaded liquid crystal nanoparticles (MD-LCNPs) that were simultaneously synthesized via a straightforward homogenization method. The preparation of MD-LCNPs involved inducing the disruption of a cubic-phase gel of glyceryl monostearate (GMS) by Milli-Q water in the presence of a Tween-80. Characterization of MD-LCNPs encompassed an assessment of their physicochemical properties. Microscopic studies revealed monodispersity with an average size of 195 ± 55.94 nm. In vitro evaluations demonstrated commendable antioxidant potential, excellent swelling behavior, and sustained release behavior of MD-LCNPs. Furthermore, MD-LCNPs exhibited nontoxicity toward cells, with minimal generation of reactive oxygen species (ROS) or nitric oxide (NO). Histopathological and hematological analysis indicated the efficacy of MD-LCNPs in ameliorating niacin-induced varicose veins, the absence of detrimental and toxic effects on blood cells and visceral organs, and safety for intravenous administration. Following the administration of nanoparticles, the formulation demonstrated appropriate levels of prostaglandins (PGDs), vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1), and vascular endothelial growth factor (VEGF). This substantiates the formulation's suitability for the treatment and management of varicose veins. In conclusion, our work shows an efficient method that induces varicose veins in rodents, and also a promising nanocarrier-based drug delivery approach using MD-LCNPs for effective and safe varicose vein therapy.

The obese population's views on the symptoms and risks of chronic venous insufficiency - 2 (OBVIOUS-2) cross-sectional survey.

Individuals with high body mass index (BMI) are more likely to have symptomatic LLVD than age matched populations with normal BMI. National priorities in venous disease set by the James Lind Alliance focus on improving access to healthcare and patient education. The aims of this study are to determine patient knowledge and potential burden of LLVD in a population of patients attending a UK, regional weight management service. A postal questionnaire containing 12 questions relating to LLVD and obesity was distributed to the active list of patients under the weight management medical service at Dudley Group of Hospitals between May 2022-23. Respondents were provided with a stamped, addressed envelope to return the questionnaire. Ethical approval was granted by the Hampshire Research & Ethics Committee. Some 367 questionnaires were distributed to patients currently enrolled in specialist weight management services. 103 complete responses were received (28%), Most patients were between 50 and 70 years of age. 25% of patients already had a formal diagnosis of LLVD, with a further 84 (82%) reported signs or symptoms which may be related to LLVD. Almost half (49/103, 48%) had concerns over their skin quality with a similar proportion (25/103, 51%) having sought medical help. The majority (71/103, 69%) were unaware of the association between obesity and LLVD. Twelve participants had education regarding simple adjuncts designed to improve symptoms and/or prevent ulceration (emollients, dressings, stockings, or leg elevation). Four participants had previously undergone treatment for varicose veins. In a population of patients accessing weight management services, we have demonstrated that a quarter of patients have already received a diagnosis of LLVD, however there is for a greater undiagnosed burden of LLVD in part due to lack of patient and possibly clinician awareness.

The Efficacy of Radiofrequency Ablation for the Treatment of Symptomatic Varicose Veins of Lower Limbs.

Radiofrequency ablation (RFA) is a minimally invasive treatment for lower limb varicose veins. Studies indicate that RFA results in immediate occlusion of 90%-100% of treated long saphenous veins. Evidence suggests that post-operative scans rarely alter patient management or outcomes. The aim of this study was to assess the potential necessity of routine postoperative scanning in the treatment of varicose veins. Retrospective data were collected for the patients who had RFA under a single consultant from November 2015 to June 2018. Descriptive statistics were calculated to summarize patient demographics, procedural details, and outcome measures. A total of 124 patients underwent radiofrequency ablation (RFA). Most of the patients (n = 114, 92%) demonstrated complete ablation, indicating a high success rate for the procedure. This study suggested that routine postoperative scanning should be discontinued as this did not alter patient management in over 99% of cases. The resources currently used for postoperative scans could be redirected towards other critical areas.

Endothelium Piezo1 deletion alleviates experimental varicose veins by attenuating perivenous inflammation.

Previous large-scale genetic studies have prioritized the causal genes piezo type mechanosensitive ion channel component 1 (PIEZO1) and castor zinc finger 1 (CASZ1) associated with varicose veins (VVs). This study aims to evaluate their roles in both clinical and experimental VVs. In this study, we investigated abundance of PIEZO1 and CASZ1 in both varicose and normal veins from the same patients. Yoda1 (a selective PIEZO1 agonist, 2.6mg/kg/day) or vehicle was administered intraperitoneally for 3weeks to evaluate the effect of PIEZO1 activation on experimental VVs. Subsequently, endothelial Piezo1 deletion mice (Piezo1iΔEC mice) were generated to explored the role of endothelial PIEZO1 on VVs. Laser speckle imaging, flow cytometry, cell tracing with Evans blue or rhodamine-6G, and histopathological staining were utilized to evaluate the pathophysiology of VVs. Our results showed that mRNA expression of PIEZO1, but not CASZ1, was abundant and increased in clinical VVs. The Piezo1tP1-td mice revealed endothelium-specific expression of PIEZO1 in mice veins. By establishing iliac vein ligation-induced VVs in mice, Yoda1 exacerbated experimental VVs with increased inflammatory cell infiltration. Subsequently, endothelial Piezo1 deletion (Piezo1iΔEC mice) alleviated experimental VVs and vascular remodeling by directly reducing vascular permeability and leukocyte-endothelium interactions compared to the control (Piezo1fl/fl mice). PIEZO1 is highly expressed in clinical VVs, meanwhile, activation or inhibition of PIEZO1 exerts a remarkable effect on experimental VVs. Furthermore, Piezo1 may constitute a potential therapeutic approach for the medical treatment of VVs.

Interventional Radiology Awareness Among Family Physicians and General Practitioners in Jazan Region, Saudi Arabia.

Background Interventional radiology (IR) utilizes minimally invasive procedures guided by imaging to diagnose and treat various conditions, offering less invasive alternatives to traditional surgery. Despite its importance, awareness among family medicine practitioners can vary, affecting patient care. While IR has advanced in Saudi Arabia, there are limited data on family medicine practitioners' understanding of IR. This study assesses awareness of IR procedures among family medicine doctors in Jazan and their perceived need for further education. Methods A cross-sectional interview-administered survey was conducted online among family medicine doctors in Jazan via social media. The survey assessed demographic data, awareness of IR procedures, self-rated knowledge, and attitudes towards IR. Participants' understanding of IR training, hospital privileges, outpatient clinics, and recognition by the Saudi Commission for Health Specialties (SCHS) was evaluated. Data were analyzed using descriptive statistics and chi-square tests. Results Out of 395 respondents, the age distribution was as follows: 20-29 years (44.3%), 30-39 years (32.9%), and 40 years or older (22.8%). Gender distribution was as follows: females (44.6%) and males (55.4%). Specialties included family medicine consultants (10.6%), residents (32.4%), specialists (22.8%), and general practitioners (34.2%). Awareness of IR procedures varied: uterine fibroid embolization (58.7%), coronary angiography (57.5%), vascular angioplasty (63.5%), radiofrequency ablation (61.3%), peripheral vascular bypass (61.8%), brain biopsy (56.2%), nephrostomy tube placement (59.5%), varicose veins treatment (63.0%), and cystoscopic tumor resection (54.7%). Self-rated knowledge was as follows: poor (46.8%), adequate (27.1%), good (15.7%), and excellent (10.4%). Most believed that interventional radiologists' training was in radiology (62.8%), with fewer attributing it to vascular surgery (20.5%) or a combination (16.7%). Regarding privileges and facilities, 248 (62.8%) reported hospital admitting privileges for IRs, 251 (63.5%) reported outpatient clinics, and 45 (11.4%) were unsure about admitting privileges. SCHS recognition was confirmed by 267 (67.6%). Referrals to IRs were made by 283 (71.6%), and 260 (65.8%) would increase referrals with more knowledge. The perceived benefit of additional education was as follows: no benefit (48.4%), some benefit (30.6%), and significant benefit (21.0%). Conclusion The study reveals gaps in awareness and knowledge of IR among family medicine doctors in Jazan. While there is recognition of IR's value and a willingness to refer patients, variations in knowledge highlight the need for targeted educational interventions. Improving education on IR could enhance integration into patient care and optimize outcomes.

Safety and efficacy of endovenous microwave ablation for treatment of varicose veins of the lower limbs in China: A prospective registered clinical trial.

This study aimed to investigate the safety and efficacy of a new Chinese device using microwave ablation for treating symptomatic great saphenous vein (GSV) varicose veins (VVs). This prospective, single-arm, single-center, cohort study investigated the safety and efficacy of endovenous microwave ablation for the treatment of symptomatic VVs. A total of 50 patients with lower limb varicose veins were enrolled from the Hospital of Chengdu University of Traditional Chinese Medicine. The clinical outcomes and complications were assessed at 1, 6, and 12 months after the procedure. The primary outcome was the occlusion rate of GSV immediately and at 1, 6, and 12 months after the treatment. The secondary outcomes included the venous clinical severity score (VCSS), the chronic venous insufficiency questionnaire 14 items (CIVIQ-14) score, the Aberdeen varicose vein questionnaire (AVVQ) score, and the pain visual analog scale (VAS) score. This study protocol was registered at ClinicalTrials.gov (ID: NCT04645771). In total, 50 limbs from 50 patients (26 female; mean age: 53.45 ± 9.78 years) were treated. A technical success rate of 100% was achieved and no serious adverse events were recorded. During the follow-up period, the occlusion rate of the major/minor saphenous vein trunk remained 100% at 1, 6, and 12 months after surgery except one patient fell off. The median 24-h VAS value was 2 (2,3). The VCSS score, CIVIQ-14 score, and AVVQ score (p < .05) at 1, 6, and 12 months improved significantly compared with the value preoperative (p < .05). EMA was safe and effective for treating varicose veins in the lower limbs, with a high rate of venous trunk occlusion and few complications, thus improving patients' postoperative quality of life.

A jugular venous compression adjunct for surgical excision of distensible orbital venous malformations

ABSTRACT Purpose Orbital venous malformations (VM) pose challenges in complete resection due to indistinct borders and bleeding proclivity. Current methods for aiding surgical excision of distensible orbital venous malformations are inadequate. We investigated whether external neck compression could facilitate intraoperative distension of venous orbital lesions during surgical excision in patients diagnosed with VM. Methods Eighteen patients (8 males and 10 females) diagnosed with distensible venous anomalies were enrolled. Neck compression technology, was employed to distend the lesions before puncture embolization using n-butyl-2-cyanoacrylate glue under general anesthesia. The surgical process, along with preoperative to postoperative changes in ocular symptoms, were recorded. Results The average surgical duration was 95 min. A mean of 3.41 ml surgical glue was used for embolization. The compression belt maintained pressure at 35–40 mmHg. Total lesion resection was achieved in 12 patients, with 6 patients undergoing subtotal removal not requiring supplementary surgery. Symptoms were entirely alleviated in 17 patients, and signs of distensible lesions during the Valsalva maneuver were absent. One patient underwent secondary surgery for residual eyelid lesions. Minor complications included mild ocular movement restriction, residual subcutaneous induration, transiently increased orbital pressure, and lower lid ectropion in four, three, four, and one patient, respectively. Three patients experienced a mild post-operative visual acuity decrease, although none experienced vision loss. Conclusions Direct orbital embolization aided by a jugular vein compression device is safe and demonstrates satisfactory outcomes in orbital varicose vein treatment.
