Recurrent Varicose Veins Research Articles

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.

Retrospective review of endovenous thermic ablation alone versus combined with phlebectomy in the management of varicose veins

Background: Chronic venous disease (CVD) affects 25-30% of the adult population in developed countries, significantly impacting quality of life. Endovenous thermal ablation (EVTA) has replaced traditional saphenectomy, but the benefit of combining it with phlebectomy remains debated. This retrospective study compares varicose vein recurrence after EVTA with and without phlebectomy. Methods: A total of 155 patients from the general hospital of Mexico between 2021 and 2024, classified as CEAP C2-C6, were analyzed. Of these, 83 underwent EVTA with phlebectomy, and 72 underwent only EVTA. Demographic data were analyzed, and recurrence rates, technical success, and complications were compared using chi-square and student’s t tests (p<0.05). Results: Recurrence rates were lower in the phlebectomy group (14.5%) compared to the non-phlebectomy group (27.2%, p=0.04). The success rate was higher in the phlebectomy group (86.7%) compared to EVTA alone (65.2%, p=0.003). There were no significant differences in complications between the groups. Conclusions: EVTA with phlebectomy demonstrated better outcomes in terms of recurrence and clinical success. However, minor complications such as bruising should be considered when choosing the treatment.

Safety of synchronous prophylactic ablation of the anterior saphenous vein in patients undergoing great saphenous vein thermal ablation- 6 months follow-up data of the SYNCHRONOUS study.

The SYNCHRONOUS-study investigates simultaneous ASV-ablation with great saphenous vein (GSV) treatment in endovenous laser ablation (EVLA) for preventing varicose vein recurrence. This sub-study examines complication rates associated with prophylactic ASV-ablation. Among 1173 patients with refluxing GSV, 604 underwent GSV-ablation only, and 569 received additional ASV-ablation. Complication rates were compared over 6months. Approximately 80% of patients were complication-free with minor bruising and dysesthesia being most common complications. After 6months, additional prophylactic ASV-ablation did not increase the rate of complications compared to GSV-only treatment. The 6-months follow-up data suggests that prophylactic ASV-closure, alongside GSV-treatment, is safe, with similar complication rates to GSV-only EVLA.

Effectiveness of Hypertonic Saline, Polidocanol, and Glycerol as Sclerosing Agent: An Experimental Study in Javan Rabbits (Lepus nigricollis)

INTRODUCTION: Therapeutic approaches to varicose veins include sclerotherapy, laser ablation, and surgery. Using sclerosing agents such as hypertonic saline, polidocanol, and glycerol can be an option in cases of recurrent varicose veins. This study aimed to assess the effectiveness of hypertonic saline, polidocanol, and glycerol as sclerosant agents in an in vivo study. MATERIAL AND METHODS: This was an experimental study on 24 Javan rabbits, divided into three treatment groups: hypertonic saline (group I, n=8), polidocanol (group II, n=8), and glycerol (group III, n=8). All animals received treatment by injection into the vein behind the ear, then vein damming 10 minutes later. Punch tissue samples for standard histopathological examination were taken from blood vessels at 1 hour, 24 hours, 7 days, and 45 days post-treatment across all groups. The histopathology changes were scored based on inflammation, proliferation, luminal narrowing, and fibrosis. RESULT: No differences were observed in the degrees of inflammation, proliferation, luminal narrowing, or fibrosis at different observation intervals. However, a significant and positive correlation was found between inflammation, vascular proliferation, and fibrosis with all sclerosing agents (p<0.005). No significant correlation exists in the scoring of luminal narrowing among any sclerosing agent (p>0.005). CONCLUSION: Hypertonic saline, polidocanol, and glycerol demonstrated comparable efficacy as sclerosing agents in vivo concerning fibrosis, vascular proliferation, and inflammation.

Analysis of the effectiveness of the method of primary bleeding prevention in the treatment of portal hypertension in children

Objective. To evaluate the role of primary prevention of variceal bleeding in children with prehepatic portal vein obstruction. Materials and methods. The single–centre prospective cohort clinical trial involved 120 patients with extrahepatic obstruction of the hepatic portal vein who underwent primary or secondary prevention of variceal bleeding in 2016–2021. Laboratory, ultrasound, and endoscopic data were collected and evaluated before and after prophylactic treatment. Results. Episodes of variceal bleeding were observed in 3 (5.78%) patients who received primary prophylaxis, and rebleeding occurred in 19 (27.94%) patients who received secondary prophylaxis (p=0.013). Of the 53 (44.17%) patients who underwent endoscopic treatment, variceal bleeding occurred in 3 (5.66%), and 19 (28.36%) of the 67 (55.83%) patients who underwent surgery experienced rebleeding (p=0.001). Esophageal varices eradication was achieved in 83 (69.17%) patients: 44 (53.01%) patients who received primary prevention and 39 (46.99%) patients who received secondary prevention. Bleeding episodes occurred less frequently after eradication (p<0.001). After primary prevention, varicose veins disappeared more often than after secondary prevention (p=0.003). The incidence of varicose veins recurrence after achieving eradication did not differ in the groups (p=0.51). Conclusions. Primary prevention can reduce the high risk of bleeding in prehepatic portal vein obstruction. Prophylactic endoscopic ligation is important in the treatment of portal hypertension in children, which, together with portosystemic shunting, can potentially improve the results of preventive treatment.

Relationship Between Diameter and Pelvic Vein Reflux

Introduction: Diameter has been a complementary measurement in the evaluation of venous valvular insufficiency of superficial veins of the lower extremity. Small veins with reflux or large veins without reflux may indicate alternative treatments. Awareness of pelvic vein reflux is increasing. The pelvic vein diameter-reflux relationship was investigated. Methods: Findings of lower extremity ultrasound (US) and/or clinical conditions—pelvic pain, dyspareunia and dysmenorrhoea—were indications for pelvic/abdominal venous US. Complete US examination included renal, internal iliac and gonadal/ovarian veins. Diameters of the largest right or left pelvic veins were compared with presence of reflux. Intravaginal US was completed in 104 women, age 46 ± 11 (standard deviation) (range 25-76) years old. Pelvic symptoms were reported by 30 (29%) patients. The other patients had pelvic-related recurrent varicose veins or suspected pelvic source of lower extremity venous reflux. Positive and negative predictive values (PPV, NPV) and other statistics at the 90-95% level were calculated relating diameter to pelvic vein reflux. Results: Pelvic vein reflux was detected in 54 (52%) women. Pelvic vein diameters were larger in refluxing, 8.4 ± 1.9 (5.1-14.0) mm, than in nonrefluxing veins, 5.2 ± 1.0 (3.4-8.3) mm ( P < .001 by t test). Diameters ≥6.3 mm had 91% (49/54) sensitivity and 92% (49/53) PPV. Diameters ≤6.3 mm had 94% specificity (47/50) and 89% (47/53) NPV. All veins with diameter ≥8.4 mm ( n = 21) had reflux. All veins with diameter ≤5.0 mm ( n = 27) did not have reflux. Conclusions: Probabilities of pelvic vein reflux were estimated based on diameters. Diameter-reflux agreement solidifies diagnosis. An explanation for contradiction between small diameter and reflux or large diameter and no reflux is recommended.

Optimization of treatment of patients with inguinal hernia in combination with recurrence of varicose veins

Introduction. In recent years, surgeons have increasingly used combined operations in patients with inguinal hernias and recurrent varicose veins. However, it is necessary to justify the choice of the type and volume of the main and concomitant stages of combined surgery, depending on the individual characteristics of both diseases.Aim. Optimization of surgical treatment of patients with inguinal hernias in combination with relapses of varicose veins.Materials and methods. The study included 39 patients aged 35 to 78 years with inguinal hernias and RVB. Of these, 21 patients who underwent combined operations were included in the main group. The control group included 18 patients who underwent staged hernioplasty, and then after 1–26 months, operations for RVB, or interventions were performed in reverse order. A comparative assessment of the duration of operations, the level of postoperative pain, immediate and long-term results, and the number of complications of uncorrected diseases in two-stage treatment was carried out.Results and discussion. Performing combined operations in this category of patients does not lead to an increase in the level of postoperative complications, it is accompanied by an average increase in the duration of surgery by 33.6 minutes and an increase in the intensity of postoperative pain by 0.8 points, a decrease in temporary disability by 1.2 times.Conclusions. Performing combined operations is the optimal intervention in patients with inguinal hernias with concomitant recurrence of varicose veins. The use of combined operations makes it possible to simultaneously eliminate both diseases and exclude the development of complications from an uncorrected disease, which, with two-stage treatment, was observed in 11.1% of cases and required emergency operations.

From the experience of more than 1000 glue ablation procedures for varicose veins: how to do it

Cyanoacrylate adhesive closure (CAC) is currently one of the main non-thermal ablation modalities of incompetent saphenous veins. High efficacy and safety of the method is supported by international clinical practice guidelines as well as the real-world practice. In contrast to thermal ablation, CAC is advantageous in terms of low periprocedural pain and bruising, fast procedure time and postprocedural recovery, high patient comfort and satisfaction rates as well as avoidance of postprocedural compression. This publication summarises the practical tips and tricks of glue ablation procedure based on 5-year experience (2019–2023) at the “SM-Clinic” Phlebology Centre, Moscow. Indications for the preferred use of CAC are formulated, such as: low pain threshold; contraindications (or unwillingness) to postprocedural compression; extensive comorbidity and fragile patients; concomitant morbid obesity; the presence of axial reflux along the saphenous veins; the need for simultaneous ablation of several incompetent truncal veins; below-the-knee incompetence of saphenous veins, including recurrent varicose veins; extensive lipodermatosclerosis and/or venous leg ulcer; patient’s HIV and viral hepatitis positive status. A step-by-step interventional protocol of glue ablation is described, including the modified protocols of the procedure. The immediate and long-term outcomes of the CAC according to current data are discussed. Special attention is paid to adverse events following CAC, as well as technical aspects of their prevention. Despite high efficacy and safety profile, today’s limitations for adoption and wider use of CAC are cost issues and lack of reimbursement.

Experts’ views on recurrence and progression of varicose veins

Introduction. Despite modern advances in technologies for the treatment and prevention of varicose veins, there is currently no radical treatment for varicose veins. The probability of recurrence of dilated veins, according to various authors, ranges from 5 to 70%. Along with the well-established concept of recurrence of varicose veins, the term progression of varicose veins is increasingly common in everyday life.Aim. To study the current understanding of the term relapse and the practical attitude of specialists involved in the treatment of varicose veins to it.Material and methods. In 2023, a survey of 117 specialists on the recurrence/progression of varicose veins was conducted. The respondents were doctors involved in the treatment of varicose veins: vascular surgeons 22.4%, phlebologists 50%, general surgeons 19.8%, specialists in ultrasound/functional diagnostics 7.8%, X-ray endovascular surgeon 0.85%. The questionnaire included 18 questions regarding the frequency of visits of patients with relapse/progression of varicose veins; views on tactics, as well as the attitude of specialists to the issue of progression and recurrence of varicose veins in patients after its surgical treatment.Results and discussion. The concept of recurrence and progression of varicose veins among specialists dealing with this pathology is not always comparable. There are differences in views both on the predisposing factors for the recurrence of dilated veins, and, accordingly, on the tactics of treatment and preventive measures. In some cases, according to statistics, they are due to specialization.Conclusions. The incidence of relapse and progression at the reception of the respondents has a slight difference. Despite the fact that there are opinions that do not correspond to generally accepted and abhorrent collegiality, mostly specialists try to separate these concepts, see differences in provoking factors and, accordingly, in recommendations.

The sonographic features of lymph node venous networks and flow patterns in patients with primary chronic venous disease.

Our study aims to enhance the understanding of lymph node venous networks (LNVNs) by summarising their anatomical, sonographic features, and reflux patterns. We examined 241 legs from 141 patients with primary chronic venous disease (CVD) using duplex ultrasound. The findings indicated variations in the shape, size, vascularity, and echogenicity of LNVN. The superficial inguinal lymph node with reflux appeared slightly larger, exhibiting higher velocities in the hilar artery. Regarding connections, venous flow within LNVN was predominantly drained through the saphenofemoral junction (SFJ), anterior accessory great saphenous vein (AAGSV), and great saphenous vein (GSV). A significant number of LNVNs were observed to be associated with anterolateral thigh tributaries. The study also identified valve cusps within LNVN. This study revealed a 12% prevalence of primary LNVN. Understanding the anatomical and haemodynamic features of LNVN informs treatment strategies and potentially helps prevent the recurrence of varicose veins.

A comprehensive ultrasound approach to lower limb varicose veins and abdominal-pelvic connections

ObjectivePelvic venous reflux may be responsible for pelvic venous disorders and/or lower-limb (LL) varicose veins. Ultrasound investigation with Doppler allows a complete study of the entire infra-diaphragmatic venous reservoir. The aim of this study was to guide and standardize the investigation of the pelvic origin of venous reflux in female patients with LL varicose veins. MethodsIn this case-control study, we applied a comprehensive ultrasound investigation protocol, which involved four steps: (1) venous mapping of the lower limbs; (2) transperineal and vulvar approach; (3) transabdominal approach; and (4) transvaginal approach. ResultsForty-four patients in group 1 (patients with LL varicose veins and pelvic escape points [PEPs]) and 35 patients in group 2 (patients with LL varicose veins without PEPs [control group]) were studied, matched by age. The median age was 43 years in both groups. The calculated body mass index was lower in group 1 (23.4 kg/m2) compared with the control group (25.4 kg/m2), and this difference reached statistical significance (P < .001). The presence of pelvic varicose veins (PVs) by transvaginal ultrasound was 86% in group 1 and 31% in group 2. Perineal PEPs were the most prevalent, being found in 35 patients (79.5%), more frequent on the right (57.14%) than on the left (42.85%) and associated with bilateral PVs 65.7% of the time. In group 1, 23 patients (52%) reported recurrent varicose veins vs eight patients (23%) in the control group (P = .008). Regarding the complaint of dyspareunia, a significant difference was identified between the groups (P = .019), being reported in 10 (23%) patients in group 1 vs one patient (2.9%) in the control group. The median diameters in the transabdominal approach of the left gonadal veins were 6.70 mm for group 1 and 4.60 mm for group 2 (P < .001). In patients with PVs in group 1, the median diameter of PEPs at the trans-perineal window was 4.05 mm. In the transvaginal examination, the mean diameter of the veins in the peri uterine region was 8.71 mm on the left and 7.04 mm on the right. ConclusionsThe identification of PEPs by venous mapping demonstrates the pelvic origin of the reflux and its connections with the LL varicose veins. For a more adequate treatment plan, we suggest a complete investigation protocol based on the transabdominal and transvaginal study to rule out venous obstructions, thrombotic or not, and confirm the presence of varicose veins in the pelvic adnexal region.

CT venography combined with ultrasound-guided minimally invasive treatment for recurrent varicose veins: a pilot paired-design clinical trial

AimTo compare 1-year outcomes of computed tomography venography (CTV) combined with ultrasound-guided minimally invasive treatment with ascending phlebography and ultrasound-guided treatment for recurrent varicose veins. Materials And MethodsConsecutive patients with unilateral recurrent varicose veins were matched by gender, age, C classification, and degree of obesity, and randomised in a 1:1 ratio to receive either CTV (CTV group) or ascending phlebography (control group) combined with ultrasound-guided minimally invasive treatment. Patients were followed up by clinical and ultrasound examination. Follow-up was scheduled at 1 week, and 3, 6, and 12 months. The primary outcome measure was the Venous Clinical Severity Score (VCSS) at 12 months. Measures of secondary outcome included Chronic Insufficiency Venous International Questionnaire-20 (CIVIQ-20) score, recurrence of varicose vein or ulcer during 12 months, ulcer healing time, detection and location of treated veins. ResultsEighty patients were enrolled. Median VCSS in the CTV group was lower than it in the control group (p=0.04) and the CIVIQ-20 score was higher than the control group (p=0.02). By 12 months, no symptomatically recurrent varicose veins or ulcers had occurred. The ulcer healing time in CTV group was shorter (p<0.01). A greater number of patients had treated veins detected using CTV than by ascending venography (p=0.01), especially among patients with recurrence reflux veins in the groin, perineum, and vulva (p<0.01). ConclusionCTV combined with ultrasound may be more helpful than ascending phlebography combined with ultrasound to improve treatment efficacy for recurrent varices. These results should be verified by an future study with more patients and long-term follow-up.

Comparative Efficacy of Postoperative Compression Methods After EVLT for Great Saphenous Vein Insufficiency.

Introduction: The preference for endovascular techniques in treating varicose veins, particularly in the great saphenous vein (GSV), has increased due to their minimally invasive nature and reduced complications. Post-operative care, especially involving compression therapy, remains crucial to improve outcomes, prevent varicose vein recurrence, and enhance overall recovery. This study aimed to evaluate the efficacy of eccentric compression therapy compared to alternative post-operative care methods following endovenous laser treatment (EVLT) for GSV insufficiency. Methods: This prospective randomized clinical trial encompassed 88 EVLT procedures for GSV insufficiency. The participants were divided into two groups, each receiving different postoperative compression methods, and were evaluated over a specified period. The primary outcome was the pain scale after EVLT; meanwhile, the secondary outcome measured in the present study was the rate of GSV occlusion after EVLT. Results: Both groups underwent all EVLT procedures successfully without any complications. At the one-month duplex ultrasound (DUS) follow-up, the sapheno-femoral junction occlusion rates were 97% (43 out of 44) for group A (eccentric compression plus gradual compression stocking) and 95% (42 out of 44) for group B (only gradual compression stocking). Ecchymosis was observed in only 12 patients across both groups, accounting for an overall occurrence of 13.6%. Group A patients reported significantly lower analgesic usage (10%) compared to group B (18%), although this difference did not reach statistical significance. Analysis of postoperative pain data utilizing the visual analog scale (VAS) showed a median value of 5.5 in group B patients, which decreased to 3.1 with the application of eccentric compression. Moreover, there was less ecchymosis in group A observed by one week. Conclusion: This study contributes to the ongoing discourse on the efficacy of postoperative compression in varicose vein treatment. It underscores the necessity for more comprehensive, well-designed studies to yield clearer conclusions and provide better guidance for post-procedure care.

Comparison of three dimensional CT venography and ascending phlebography based on propensity score matching in the evaluation of recurrent varicose veins

Objective: To compare the efficacy of lower extremity three dimensional CT venography (CTV) and lower extremity ascending phlebography in evaluating recurrent varicose veins. Methods: A retrospective analysis was conducted on clinical data from 235 patients with unilateral recurrent varicose veins who were treated at the Department of Vascular Surgery,Beijing Shijitan Hospital,Capital Medical University, between January 2015 and December 2020.There were 112 males and 123 females, with an age of (62.5±11.4)years (range:24 to 75 years).Patients were stratified into two groups based on preoperative imaging examination:the CTV group (utilizing lower extremity venous ultrasound+lower extremity CTV) and the control group (employing lower extremity venous ultrasound+lower extremity ascending phlebography).The two groups were matched in a 1∶1 ratio using propensity score matching, resulting in 43 cases per group.Comparative analyses between the groups at the one-year postoperative follow-up were performed using independent sample t tests, Wilcoxon rank-sum tests, χ2 tests, and linear regression analysis. Results: One year post-surgery,the CTV group exhibited a lower venous clinical severity score (VCSS) compared to the control group(M(IQR),3.0(4.3) vs.4.0(5.8),Z=-2.038,P=0.040).Additionally, the chronic venous insufficiency patients' quality of life questionnaire (CIVIQ-20) scores were significantly higher in the CTV group than in the control group (89.0(8.0) vs.82.5(17.0), Z=-2.627, P=0.010).Patients in the CTV group also experienced a shorter ulcer healing time compared to the control group (4.0(4.0) weeks vs.12.0(7.0) weeks, Z=-3.217,P<0.01).Both groups showed no clinically symptomatic recurrent varicose veins or ulcers.However, they exhibited ultrasound-detectable varicose vein recurrence, with no statistically significant difference (χ2=0.453,P=0.500).The number of diseased vessels requiring management based on ultrasound supplemented by CTV was 16, while the number supplemented by ascending phlebography was 7,with a statistically significant difference (χ2=4.800,P=0.030).Linear regression analysis demonstrated that clinical-etiology-anatomy-pathology clinical grading and the preoperative imaging examination method exerted independent influences on VCSS and CIVIQ-20 during the one-year postoperative assessment. Conclusions: CTV-assisted ultrasound enables a direct and comprehensive evaluation and localization of diseased veins in patients with recurrent varicose veins.The utilization of lower extremity vein ultrasound combined with CTV-guided management of lower extremity vessels in minimally invasive treatment significantly improves patient prognosis, surpassing the assessment provided by ascending phlebography.

Surgical Treatment of Varicose Veins of the Lower Extremities

The review presents an analysis of relevant literature on the surgical treatment of varicose veins of the lower extremities. Modern methods of surgical intervention for varicose veins are considered: open operations, methods of thermal ablation of the main veins, non-thermal non-tumescent methods, vein-preserving surgery (ASVAL), methods of treating reflux in perforating veins and recurrent varicose veins. The effectiveness of each of the surgical treatment methods used was analyzed. The frequency of relapses and the likelihood of complications of the described operations are considered. All surgical treatment methods presented in the review were developed on the basis of modern ideas about the pathogenesis of varicose veins, the mechanisms of formation of chronic venous insufficiency, and have an evidence base. These techniques are reflected in the latest clinical guidelines and are widely used in medical practice.

Clinical Efficacy of a Modified Surgical Procedure in the Treatment of Incompetent Great Saphenous Veins.

The aim of this study was to evaluate the clinical efficacy of a modified surgical procedure for the treatment of varicose veins. This retrospective analysis was conducted on lower extremities with symptomatic great saphenous vein (GSV) incompetence that underwent stripping from the groin to the knee, with preservation of the superficial epigastric vein (SEV), between January 2015 and April 2022. Follow-up assessments were performed using Doppler ultrasound, Venous Clinical Severity Score (VCSS), and the Aberdeen Varicose Vein Questionnaire (AVVQ) at 6 and 12 months after surgery. The study included 179 limbs from 120 patients (47 men and 73 women). The mean patient age was 56.5 years (range, 20-78 years), and the distribution of preoperative Clinical-Etiology-Anatomy-Pathophysiology clinical classes was 8% C0-C1, 88% C2, and 4% C3-C6. The preoperative diameter of the saphenofemoral confluence averaged 6.9 mm (range, 2.7-15.8 mm). After a mean postoperative follow-up period of 24 months, evidence of neovascularization around the stump of the saphenofemoral junction (SFJ) was observed in 2 limbs (1.1%). Additionally, varicose vein recurrence was found in 1 limb (0.6%) and was associated with an incompetent thigh perforator. At postoperative follow- up, both VCSS and AVVQ scores were significantly lower than the preoperative scores. Modified surgical treatment of GSV incompetence, involving preservation of the SEV and stripping of a short segment up to the knee, demonstrated favorable clinical results in terms of postoperative complication rate, neovascularization rate around the SFJ stump, varicose vein recurrence rate, and improvement in lower extremity symptoms.

Factors influencing recurrent varicose vein formation after radiofrequency thermal ablation for truncal reflux performed in two high-volume venous centers

ObjectiveRecanalization of the saphenous vein trunk after endovenous radiofrequency ablation (RFA) is often associated with recurrent varicose veins (RVVs) or recanalization. This study aimed to assess the long-term results of RFA of the great saphenous vein (GSV) and identify the risk factors for GSV recanalization and RVVs during follow-up for patients presenting to dedicated outpatient vein centers. MethodsAll consecutive patients with incompetent GSVs who underwent RFA between 2009 and 2019 were retrospectively analyzed. The primary study end points were freedom from GSV recanalization and the RVV rate during follow-up. The secondary study end points were the postoperative complication rate and the risk factors for GSV recanalization and RVVs. Univariate and multivariate analyses were performed to identify the potential risk factors for GSV recanalization and RVVs. ResultsDuring the study period, 1568 limbs were treated in 1300 consecutive patients (mean age, 53.5 ± 12.9 years; 71.9% women; CEAP [clinical, etiology, anatomy, pathophysiology] C2-C6; venous clinical severity score >5). Technical success was achieved in 99.7% of cases. At a mean follow-up of 57.2 ± 25.4 months, the GSV occlusion and freedom from reintervention rates were 100% and 100% within 1 week, 97% and 95.7% at 1 year, 95.2% and 93.1% at 3 years, and 92.4% and 92.8% at 5 years, respectively. The recurrence rate was 10% (n = 158) during the follow-up period. On multivariate analysis, a direct confluence of the accessory saphenous vein into the saphenofemoral junction (odds ratio [OR], 1.561; 95% confidence interval [CI], 1.0-7.04; P = .032), a history of pregnancy >2 (OR, 3.68; 95% CI, 1.19-11.36; P = .023), C4 (OR, 6.41; 95% CI, 1.36-30.28; P = .019), and preoperative GSV diameter >10 mm (OR, 1.82; 95% CI, 1.65-4.03; P = .043) were risk factors for GSV recanalization. Moreover, age >70 years (OR, 1.04; 95% CI, 1.01-1.06; P = .014) and incompetent perforator veins (OR, 1.17; 95% CI, 0.65-2.03; P = .018) were also risk factors for RVVs. ConclusionsRFA is a safe technique to ablate the GSV with a low complication rate and durability during 5 years of follow-up. However, patients with a high clinical score and those with direct confluence of the accessory saphenous vein into the saphenofemoral junction experienced higher long-term GSV recanalization and RVV rates.

Effectiveness of iliac vein stenting combined with endovenous laser treatment of recurrent varicose veins associated with iliac vein compression.

Iliac vein compression syndrome (IVCS) is an underlying cause of varicose vein (VV) recurrence after venous surgery. However, the management of recurrent varicose veins (RVVs) combined with IVCS has rarely been reported. This study aimed to investigate the outcomes of a one-stop procedure to correct outflow obstruction and superficial reflux for patients with RVVs and IVCS. A retrospective analysis was conducted of 102 consecutive patients diagnosed with RVVs. Computed tomography venography (CTV) was performed to confirm IVCS. The cases were divided into 2 groups: the IRVVs group, including patients with RVVs and IVCS (n=48), and the RVVs group, including patients with RVVs only (n=54). The characteristics, vein reflux, and clinical, etiological, anatomical, and pathophysiological (CEAP) distribution were investigated. Then, the IRVVs group patients who underwent endovenous laser ablation (EVLA) (n=39) were divided into a further 2 groups: the EVLA + S group (n=19), who received EVLA and stenting of iliac vein, and the EVLA group (n=20), who received EVLA treatment alone. The great/small saphenous vein (GSV/SSV) trunk occlusion, VV recurrence, visual analogue scale (VAS), and venous clinical severity score (VCSS) were investigated. The prevalence rate of femoral vein reflux was 81.2% in IRVVs group and 50% in RVVs group (P<0.05). In the IRVVs group, 72.9% of patients manifested as CEAP clinical class >3, which was higher than that in RVVs group (48.1%) (P<0.05). The 12-month GSV/SSV occlusion rate in the EVLA + S and EVLA groups were 94.7% and 90.0%, respectively. Totals of 9 patients in EVLA + S group and 6 patients in EVLA group had active venous ulcers, and the ulcer healing time in EVLA + S group was significantly shorter (27.22±7.12 vs. 46.67±9.83 days, P<0.05). The reductions in the VAS and VCSS values between baseline, 1 month, and 12 months in the EVLA + S group were more obvious than those in EVLA group (P<0.05). The one-stop combination treatment of iliac venous stenting and EVLA in patients with RVVs and IVCS is safe and effective and provides prominent symptom relief, improved quality of life, and a more satisfactory ulcer healing than EVLA alone.
