Intraoperative Intermittent Pneumatic Compression Reduces Incidence of Venous Thromboembolism in Patients Undergoing Craniotomy: Study Protocol of a Randomized Multicenter, Single-Blind Trial

BACKGROUND AND OBJECTIVE: Venous thromboembolism (VTE), which includes deep vein thrombosis (DVT) and pulmonary embolism (PE), is a common complication in craniotomy patients. The duration of surgery has been identified as a risk factor for the development of VTE. In a pilot study, the use of intermittent pneumatic venous compression (IPC) dramatically reduced the incidence of VTE. Despite randomization, a significant difference in the duration of surgery between the groups limited the validity of this result. The study was underpowered to compensate for this problem. We now present the protocol of a multicenter trial. METHODS: All patients receive medical compression stockings and low-molecular-weight heparin from the first postoperative day. The therapy group receives IPC stockings intraoperatively. Postoperatively, all patients receive lower-extremity duplex sonography to detect/exclude DVT within the first 7 postoperative days. Contrast-enhanced chest CT is the gold standard for the detection of PE and is performed in cases of clinical suspicion of PE. EXPECTED OUTCOMES: The incidence of VTE is the primary end point. The distinction between symptomatic and asymptomatic, etiologies, influence of lesion type, duration of surgery, and mortality will be evaluated as secondary end points. The pilot study showed a VTE incidence of 26% in the control group vs 7% in the treatment group. To avoid overly optimistic treatment effect assumptions, we assume VTE rates of 9% and 24% in the treatment and control groups, respectively, and thus calculated a number of 127 patients per treatment group. DISCUSSION: If this trial shows that intraoperative IPC reduces the risk of VTE to the extent observed in our pilot study (number needed to treat: 5.24), the potential benefit to neurosurgical patients would be significant. The results would potentially influence treatment guidelines by providing the high-quality evidence needed to make robust recommendations.

Nodular vasculitis – Retrospective study of an uncommon disease in a non-tuberculosis endemic country with focus on treatment modalities and efficacy

Introduction Nodular vasculitis (NV) is a rare form of panniculitis primarily affecting middle-aged females, presenting as painful, sometimes ulcerated nodules on the dorsal lower legs. Erythema induratum Bazin (EIB) is a form of NV and is considered a manifestation of cutaneous tuberculin hypersensitivity. This retrospective study aims to analyze demographics, clinicopathological findings, laboratory results, and treatment outcomes of NV in a non-TB endemic country. Methods: Data of NV patients were extracted from the electronic hospital database of the University Hospital Zurich. Patients were included only if histopathologically confirmed diagnosis of NV and sufficient information on demographics, treatment, and follow-up was available. Results: We conducted a 20-year retrospective study , including 62 patients with NV. The most common site of involvement was the lower extremities. Disease duration varyied from several months to over 20 years. Histopathological examination revealed lobular panniculitis, with or without vasculitis, and granuloma formation. Tuberculosis association was assessed through the QuantiFERON test and Mycobacteria PCR, showing positive results in 22 or 37 (59%) tested cases and in 2 out of 27 cases (7.4%), respectively. . Comorbidities were found in over half of the patients. Treatment modalities included topical corticosteroids, antitubercular therapy, systemic steroids, and potassium iodide. Almost 50% of all patients experienced relapses despite treatment. Conclusion: Topical steroids, antitubercular therapy, systemic steroids, and potassium iodide showed similar response rates. Tuberculostatic therapy upon detecting latent TB is recommended. Considering the high recurrence rate and potential side effects of systemic therapies, we recommend first-line treatment with potent topical steroids and compression stockings.

Elephantiasis and its cure: case report

Introduction: Lymphedema is a clinical condition stemming from a lymphatic system failure. The insufficiency of the lymphatic system can causes the abnormal accumulation of protein-rich fluid in the interstitial, which triggers a adverse consequence such a and fibrosis. This study describes a case of a patient who has been cured of elephantiasis for ten years but continues to have lymphedema. Description case: Patient information: A 78-year-old woman had a history of bilateral lower limb lymphedema, clinical diagnosis that had been worsening throughout her life bilateral despite undergoing treatment and had progressed to stage III (elephantiasis). Clinical findings: The patient was sent to the Clínica Godoy-Sao Jose do Rio Preto-Brazil ten years ago and reported having undergone several forms of treatment, but without impeding the progression of the condition. Therapeutic intervention: The patient was submitted to intensive treatment for three weeks, during which time a 21-kilogram reduction in weight and a 66-cm reduction in circumference occurred. After three weeks, the patient began undergoing treatment at home with laced compression stockings. At the follow-up evaluation, electrical bioimpedance analysis, perimeter measurements and volumetry were performed, which revealed the reduction in lymphedema to standards of normality. The patient has completed 10 years of treatment and has maintained the results using compression stockings. Conclusion: Elephantiasis is curable, but lymphedema is not. Like any other chronic disease, constant treatment is needed to maintain the results.

[Translated article] Thrombotic Event Prevention in Patients Undergoing Posterior Lumbar Arthrodesis: our experiencie. A retrospective case series study

There is no generalized consensus regarding perioperative prophylaxis of venous thromboembolism (VTE), either on using or timing it in patients undergoing spine surgery. VTE is a current concern because, even though being an uncommon event, it can cause serious complications. The aim of the present study is to propose guidelines for the prevention of thrombotic events in posterior spinal surgery, either as deep vein thrombosis or pulmonary thromboembolism. If the number of patients getting prophylaxis drugs is reduced a subsequent reduction of the incidence of epidural hematoma can be expected. A number of 235 patients who had undergone posterior spinal arthrodesis in the previous five years were studied. Mechanical thromboprophylaxis measures consisting of compression stockings were applied in all of them. Anticoagulant drugs were also applied whenever risk factors for thrombosis were observed. Early weight-bearing was resumed immediately after surgery. Demographic, clinical, and surgical variables were collected, as well as complications appearing during the follow-up period, that was scheduled at one, two, four, six and twelve months after the surgery. Thrombotic events, if present, were diagnosed by clinical and imaging tests such as ultrasound and CT angiography. From the total 235 patients of this series, one hundred and fifty-three cases met the study inclusion criteria. A total of four thrombotic events appeared, one in the form of deep vein thrombosis and other three in the form of pulmonary thromboembolism. These last patients suffering an embolism died because of it. None of the variables studied had statistical significance for the occurrence of a thrombotic event. All four patients who suffered thrombotic events were receiving anticoagulant drugs, in addition to mechanical compression stockings, because of the presence of risk factors for thrombosis. By applying the fore mentioned protocol, adequate prevention of thromboembolic events was achieved in this study population of patients undergoing posterior spinal surgery.

Smart Compression Sock for Early Detection of Diabetic Foot Ulcers.

The prevention of diabetic foot ulcers remains a critical challenge. This study evaluates a smart compression sock designed to address this issue by integrating temperature, plantar pressure, and blood oxygen sensors and monitoring data recorded by these sensors. The smart sock, developed with input from a certified Pedorthist, was tested on 20 healthy adult participants aged 16 to 53. It includes four temperature sensors and pressure sensors at common ulcer sites (first and fifth metatarsal heads, calcaneus, and hallux), and a blood oxygen sensor on the hallux. The sensors are monitored, and their transduced data are collected and stored through an app installed on a personal cell phone. The mobile app interface is user-friendly, providing intuitive navigation and easy access to the sensors' data. Using repeated measures ANOVA and post hoc tests, we analyzed the impact of various physical activities on physiological changes in the foot. The device effectively detected significant variations in blood oxygen, temperature, and pressure across six activities. Statistical analyses revealed significant differences based on activity type and sensor location. These results highlight the smart sock's sensitivity and accuracy, suggesting its potential to prevent diabetic foot ulcers. Further clinical trials are needed to evaluate its efficacy in a larger, more diverse population.

<i>Objective</i>: To investigate the effect of nursing program improvements on improving the utilization rate of gradient compression stockings in patients at high risk of deep vein thrombosis. <i>Methods</i>: To set up a special project improvement group, determine the topic of special project improvement, set 40 patients with postoperative Caprin score >5 before the implementation of special project improvement activities, i.e., from January to May 2022 in our hospital, as the control group, and 40 patients with postoperative Caprin score >5 after the implementation of special project improvement activities, i.e., from July to November 2022 in our hospital as the experimental group, and count the number of patients using gradient compression stockings to prevent deep vein thrombosis, and investigate the effect of using gradient compression stockings in improving the utilization rate of patients with high risk of deep vein thrombosis. The number of patients using gradient compression stockings to prevent deep vein thrombosis, the survey of patients' knowledge about deep vein thrombosis and satisfaction with care, and the comparison of the differences between the two groups before and after the project improvement. <i>Results</i>: The use rate of gradient compression stockings in the experimental group was 82.5% higher than that of gradient compression stockings in the control group, which was 15%, with statistically significant differences (p < 0.05); the experimental group's knowledge of DVT was higher than that of the control group, with statistically significant differences (p < 0.05); and the experimental group's satisfaction with nursing care increased from 91.73 points to 98.75 points, with statistically significant differences (p < 0.05). <i>Conclusion</i>: Project management can effectively increase the utilization rate of gradient compression stockings for high-risk patients with deep vein thrombosis and improve patients' knowledge of deep vein thrombosis and satisfaction with nursing care.

Transformative Deep Vein Thrombosis Prophylaxis With Sequential Compression Devices in the Care of Hospitalized Patients.

Deep vein thrombosis (DVT) is a critical complication and concern in hospitalized patients due to its significant morbidity and mortality. Given the complex and multifaceted pathophysiology surrounding DVT formation, patients who have had surgical interventions faced acute or chronic trauma and prolonged immobility are at substantially high risk. Identifying these risk factors early is essential for early intervention and prophylaxis. Current standard-of-care prophylaxis for DVT includes pharmacological agents such as anticoagulants, and recently, there has been an increase in the use of mechanical medical devices such as sequential compression devices (SCDs). Pharmacological prophylaxis, while shown to be effective in some patients, carries certain risks of complications such as bleeding. SCDs offer a safer and more effective approach for these patients. SCDs function by artificially replicating the "pumping mechanism" present in the soleus muscle to enhance venous return and reduce stasis. Various types of SCDs, namely intermittent pneumatic compression and graduated compression stockings, have demonstrated clinical efficacy when used as an adjunctive intervention with anticoagulant medications. This narrative review explores the pathophysiology, risk factors, and prophylactic measures for DVT, focusing on the use of SCDs as a non-pharmacological intervention. Through synthesizing evidence from various studies obtained from PubMed, MEDLINE, and Cochrane Library and evaluating the benefits and limitations of SCD use, this review highlights the need for tailored prophylactic strategies, considering patient-specific risk factors and preferences.

Obstetric management for pregnant women with Klippel-Trenaunay syndrome: A UK case report and review of the literature.

Klippel-Trenaunay Syndrome (KTS) is a rare congenital vascular disorder characterized by extensive capillary and venous malformations that pose unique challenges during pregnancy. This case report discusses the successful management of a 34-year-old pregnant woman with KTS who had two caesarean sections, resulting in the birth of two healthy babies. Despite the lack of evidence-based guidelines for obstetrical management in KTS, a multidisciplinary team collaborated to devise a high-risk thrombosis management plan, involving the use of compression stocking and low molecular weight heparin prophylaxis. The patient's elevated risk of thrombosis, exacerbated during pregnancy, informed the decision of caesarean sections, aligning with finding that in most KTS pregnancies, this method of delivery based on obstetric indications and arteriovenous malformations is chosen. This case highlights the importance of systematic and patient-centered care, advocating for comprehensive obstetric management guidelines to address the unique challenges posed by KTS during pregnancy. Further research is warranted to enhance our understanding and refine guidelines for individuals with vascular abnormalities linked to KTS.

THE EFFECT OF COMPRESSION STOCKING ON LEGS’ GEOMETRY CHANGES WITHIN DIFFERENT MOVEMENT

In this study, the changes in leg size and shape as well as pressure at different sites of a lower leg were investigated using advanced tools such as the Move4D scan system and Texsens pressure measuring device. The effect of the class of compression stocking, wearing time, and movement type was analyzed for one volunteer. It is the basis for the high-accuracy ready-to-wear compression stocking development based on the concept of personalization.

Effectiveness of Compression Therapy on Lower Extremity Oedema in Heart Failure Patients: A Case Study

Background: Heart Failure is a condition that the heart can not pump enough blood to meet the circulatory needs used in the body's metabolic processes. Patients with heart failure disease may experience swelling (oedema) in certain parts of the body, especially the lower extremities. Oedema that is not treated will exacerbate damage to the circulatory system. One of the treatments for lower extremity oedema in heart failure patients can be done by giving compression therapy. Purpose: The purpose of this study is to determine the effectiveness of compression therapy on lower extremity oedema in heart failure patients. Method: This research is a case study that managed one patient with heart failure disease who has lower extremity oedema. Data collection was carried out by observation, interview and provision of interventions carried out for 4 days using moderate pressure (20-30 mmHg). This research use compression stocking for 18 hours within 24 hours. Compression therapy is given once a day that the stocking is used at 14.00 WIB and removed at 08.00 WIB on the following day. The instrument used in this study was the pitting oedema observation sheet. Result: The results of this study were a decrease in the degree of pitting oedema in patients from a value of +3 with a depth of 5 mm in a return time of 65 seconds to a value of +1 with a depth of 1 mm in a return time of 2 seconds. Conclusion: Compression therapy is effective in reducing the degree of pitting oedema in patients with heart failure. Compression therapy has optimal effectiveness on the third day of intervention. Therefore, this therapy is highly recommended to be applied in the inpatient room, especially in patients with heart failure who have oedema in lower extremity.

Comparative Analysis of Muscle Activity and Circulatory Dynamics: A Crossover Study Using Leg Exercise Apparatus and Ergometer.

Background and Objectives: Bedridden patients are at a high risk of venous thromboembolism (VTE). Passive devices such as elastic compression stockings and intermittent pneumatic compression are common. Leg exercise apparatus (LEX) is an active device designed to prevent VTE by effectively contracting the soleus muscle and is therefore expected to be effective in preventing disuse of the lower limbs. However, few studies have been conducted on the kinematic properties of LEX. Therefore, this study aimed to compare the exercise characteristics of LEX with those of an ergometer, which is commonly used as a lower-limb exercise device, and examine its effect on the two domains of muscle activity and circulatory dynamics. Materials and Methods: This study used a crossover design in which each participant performed both exercises to evaluate the exercise characteristics of each device. Fifteen healthy adults performed exercises with LEX and an ergometer (Terasu Erugo, SDG Co., Ltd., Tokyo, Japan) for 5 min each and rested for 10 min after each exercise. Muscle activity was measured using surface electromyography (Clinical DTS, Noraxon, Scottsdale, AZ, USA), and circulatory dynamics were recorded using a non-invasive impedance cardiac output meter (Physioflow Enduro, Manatec Biomedical, Paris, France). The primary outcome was the mean percentage of maximum voluntary contraction (%MVC) of the soleus muscle during exercise. Results: The mean %MVC of the soleus muscle was significantly higher in the LEX group, whereas no significant differences were observed across the periods and sequences. Heart rate, stroke volume, and cardiac output increased during exercise and decreased thereafter; however, the differences between the devices were not significant. Conclusions: LEX may not only have a higher thromboprophylaxis effect, but also a higher effect on preventing muscle atrophy as a lower-extremity exercise device. Additionally, LEX could potentially be used safely in patients who need to be monitored for changes in circulatory dynamics.

Advances in Thromboprophylaxis for High-Risk Pregnancies: A Comprehensive Review of Current Strategies and Emerging Approaches.

Thrombosis during pregnancy poses a significant clinical challenge due to its potential for severe maternal and fetal complications. The incidence of thromboembolic events in pregnant women is heightened by pregnancy-associated hypercoagulability, venous stasis, and endothelial changes, all of which contribute to an elevated risk. Effective thromboprophylaxis is essential to mitigate these risks and improve outcomes for both mother and child. This review provides a comprehensive evaluation of current thromboprophylaxis strategies, including pharmacologic interventions such as low-molecular-weight heparins (LMWHs) and unfractionated heparin (UFH) and nonpharmacologic measures like compression stockings and lifestyle modifications. Additionally, the review explores emerging approaches, including personalized medicine strategies, novel anticoagulants, and technology-enabled monitoring solutions. By integrating current evidence with emerging trends, this review aims to offer insights into optimizing thromboprophylaxis in high-risk pregnancies, ultimately contributing to improved clinical outcomes and guiding future research directions in this critical area of maternal healthcare.

Prevalence of Varicose Veins Among Surgeons: A Cross-Sectional Study.

Background Extended periods of standing, obesity, female sex, and older age are risk factors associated with a higher probability of developing varicose veins (VV). This study aimed to determine the prevalence of VV among surgeons in public hospitals inMakkah, Saudi Arabia, and to identify the risk factors associated with this condition. Methodology This is a descriptive cross-sectional study based on a validated online questionnaire distributed via hospital WhatsApp(Meta Platforms Inc., Menlo Park, CA) groups conducted between January and June 2024. The inclusion criteria of this study were surgeons of both sexes and any age group working in the selected hospitals in Makkah City, who agreed to participate in the study. The exclusion criteria were any other healthcare workers from outside the surgical field. We included 192 participants, and Epi Info software (Centers for Disease Control and Prevention, Atlanta, GA) was used to calculate the sample size. The data were collected, reviewed, and then fed into IBM SPSS Statistics software for Windows version 21 (IBM Corp., Armonk, NY). Every participant filled out a consent form. The university ethics committee of Umm Al-Qura University, Makkah, granted ethical permission. Result This study comprised 192 surgeons in Makkah hospitals. Twenty-eight surgeons were either diagnosed with VV or had signs of VV. Varicose veins were detected among 50% of thoracic surgeons, 42.9% of pediatric surgeons, and 26.3% of orthopedic surgeons. The most reported risk factors were a family history of VV (17%), hypertension (16%), and diabetes mellitus (14%). Surgeons aged 40 years or older had a higher prevalence of VV than younger ones. Also, 55.6% of obese surgeons had VV compared to 7.8% of others with average weight. Conclusion We found that VV is a common problem, particularly among individuals with predisposing factors, such as long standing hours, smoking, pregnancy, and obesity. We found that surgeons specializing in thoracic and pediatric specialties and female surgeons were more likely to be affected by VV. Preventive measures, such as avoiding prolonged standing, wearing compression stockings, and maintaining a healthy lifestyle, are recommended.

Effects of washing on structural parameters of medical compression stockings

PurposeThis study aims to evaluate how the structure of medical compression stockings, including three compression levels and five cross-sections from the ankle to the thigh part, will be changed after washing in different conditions and further investigate the effect of the washing parameters on the medical compression stockings.Design/methodology/approachBy washing medical compression stockings in different conditions and measuring the structures (including the density, the girth, the transversal and lengthwise dimension, the weight per unit area and the thickness) of medical compression stockings from the knee to the thigh part.FindingsIt was concluded that the density, the weight per unit and the thickness increase and the girth, the transversal and lengthwise dimension, the weight per unit and the thickness decrease. The change degree of Class one and Class two is greater than Class 3. Moreover, the washing temperature is the most significant factor affecting all the structures of medical compression stockings. Meanwhile, the mechanical actions of the washing machine, like drum speed and washing time, also influence different medical compression stockings structures to different degrees.Research limitations/implicationsThe washing parameter not only includes the temperature and washing cycles but also has other factors, such as the drum speed and washing time. In addition, different kinds of factors will be influenced by each other.Originality/valueThis study can provide consumers advices on the washing of medical compression stockings, and attribute to the optimization of materials and structures to maintain its properties for manufacturers.

Tailoring Management of May-Thurner Syndrome : Case Comparison

Background: May-Thurner syndrome (MTS) is a post-thrombosis syndrome (PTS) of the lower extremity. This disorder results from compression and/or irritation from adjacent crossing the right common iliac artery to the left iliac venous. In this report, we present two management comparisons of patients with left lower DVT with consideration of MTS. Case Illustration: The first patient is a 49-year-old male soldier presented with chronic unilateral left leg edema and a mild clinical presentation for 9 months. Previous Doppler ultrasonography (DUS) revealed a thrombus in the left venous femoralis. Anticoagulant was given for six months. DUS and CT venography following anticoagulant treatment revealed a thrombus in the left venous femoralis. Venography revealed entire blockage of the left common femoral and left iliac veins, with adequate collateral flow. PTV was attempted twice and failed both times. The patient was following a conservative therapy (walking exercise and stocking compression) that yielded positive outcomes. The second patient is a 53-year-old male soldier has had unilateral left leg edema for three years, which has increased during the previous three months with ulceration and active bleeding. Previous Doppler ultrasonography revealed a thrombus in the left iliac externa. Anticoagulants and compression stockings were given for eight months, but the symptoms persisted. CT and venography revealed a complete blockage from the left popliteal vein to the iliac vein. Femoral crossover bypass surgery yielded favorable results. Conclusion: Clinically moderate MTS demonstrated fair results with conservative treatment, whereas clinically severe MTS showed superior results with bypass surgery.

Extensive Left Sided Venous Thrombi and Bilateral Pulmonary Emboli in the Context of May-Thurner Syndrome for a Patient Presenting with Acute Flank Pain: A Case Report

May-Thurner syndrome is an underappreciated differential in the context of deep venous thrombosis. It is a symptomatic congenital abnormality resulting from compression of the left common iliac vein, sometimes also referred to as iliac vein compression syndrome in the literature. This case reports the presentation of a female with acute flank pain to the emergency department following a recent laparotomy for a complicated tubo-ovarian abscess. She was subsequently diagnosed with a sub-acute thrombus extending from the left common femoral vein into the left inferior vena cava, as well as new bilateral pulmonary emboli. As the patient had relative contraindications to thrombolysis, a shared decision was made with the vascular team to opt for conservative management only. In this instance, this included long-term oral anticoagulant therapy and compression stockings. This case asserts that clinicians should maintain a high index of suspicion for May-Thurner syndrome in the context of extensive left-sided thrombus formation.

Integrated Wearable System for Monitoring Skeletal Muscle Force of Lower Extremities.

Continuous monitoring of lower extremity muscles is necessary, as the muscles support many human daily activities, such as maintaining balance, standing, walking, running, and jumping. However, conventional electromyography and physiological cross-sectional area methods inherently encounter obstacles when acquiring precise and real-time data pertaining to human bodies, with a notable lack of consideration for user comfort. Benefitting from the fast development of various fabric-based sensors, this paper addresses these current issues by designing an integrated smart compression stocking system, which includes compression garments, fabric-embedded capacitive pressure sensors, an edge control unit, a user mobile application, and cloud backend. The pipeline architecture design and component selection are discussed in detail to illustrate a comprehensive user-centered STIMES design. Twelve healthy young individuals were recruited for clinical experiments to perform maximum voluntary isometric ankle plantarflexion contractions. All data were simultaneously collected through the integrated smart compression stocking system and a muscle force measurement system (Humac NORM, software version HUMAC2015). The obtained correlation coefficients above 0.92 indicated high linear relationships between the muscle torque and the proposed system readout. Two-way ANOVA analysis further stressed that different ankle angles (p = 0.055) had more important effects on the results than different subjects (p = 0.290). Hence, the integrated smart compression stocking system can be used to monitor the muscle force of the lower extremities in isometric mode.

Anticoagulation and compression therapy for proximal acute deep vein thrombosis.

The treatment of proximal deep vein thrombosis (DVT) of the lower limbs includes an initial management phase, covering the first 1 to 3 weeks, a primary treatment phase, lasting a minimum of 3 months, and a secondary treatment phase for those patients requiring continuing anticoagulation beyond the first 3 to 6 months. During the initial phase most patients with DVT can be managed as outpatients. Exclusion criteria for home treatment include high risk of bleeding, limb threatening DVT or other conditions requiring hospitalisation. Anticoagulant drugs represent the mainstay of treatment and include parenteral drugs such as unfractionated heparin or low molecular weight heparin, and oral drugs such as the vitamin K antagonists and the direct oral anticoagulants (DOACs). DOACs are currently recommended as the first line of treatment for proximal DVT of the lower limbs, with no preference for one DOAC over another. Factors to consider when choosing the anticoagulant strategy include, among others, renal and liver function, underlying diseases such as cancer or the antiphospholipid syndrome, and patient preferences. Indefinite duration of anticoagulation beyond the first 3 to 6 months is recommended for patients with unprovoked DVT and patients with permanent, chronic risk factors. Two DOACs, namely apixaban and rivaroxaban, can be administered at low doses for the secondary prevention of DVT. Elastic compression stockings (ECS) have been used for decades in patients with proximal DVT with the aim of counteracting the venous hypertension generated by the vascular disorder and reducing leg edema and to prevent the post-thrombotic syndrome.

Prophylactic effect of compression stockings for elevated D-dimer levels following endoscopic submucosal dissection.

A relationship between endoscopic submucosal dissection (ESD) and deep vein thrombosis has been recognized. We previously reported that a high corrected midazolam dose (total midazolam dose/initial dose of midazolam used to induce sedation) is related to elevated D-dimer levels after ESD. In this study, the effect of compression stockings (CSs) in preventing thrombosis following ESD under sedation was evaluated by measuring D-dimer levels before and after ESD. The participants were patients who underwent ESD for upper gastrointestinal tumors during the period between April 2018 and October 2022. Patients with pre-ESD D-dimer levels ≥1.6 µg/m and patients with corrected midazolam doses ≤3.0 were excluded. A retrospective investigation of the relationship between CS use and high post-ESD D-dimer levels (difference in D-dimer levels ≥1.0 µg/mL between before and after ESD) was conducted. There were 27 patients in the non-CS group (NCS) and 33 patients in the CS group. The number of patients with high post-ESD D-dimer levels was 13 (48.2%) in the non-CS group and six (18.2%) in the CS group; the number in the CS group was significantly lower (p = 0.024). On logistic regression analysis, a relationship was seen between the wearing of CSs and a lower number of patients with high post-ESD D-dimer levels (odds ratio 0.24, 95% confidence interval 0.08-0.79, p = 0.019). Wearing CSs was related to a lower risk of high post-ESD D-dimer levels. This result suggests that thrombus formation is a cause of elevated D-dimer levels after ESD.
