Varicose Veins of Lower Limb

A prospective cohort study of patients with primary varicose veins to assess the morbidity, risk factors and development of chronic lower limb vein disease.

The HEMOVAR Study is a prospective observational study designed to evaluate the association between hemorrhoidal disease and lower extremity varicose veins. A total of 400 adult patients presenting to the general surgery proctology outpatient clinic of Aydın Adnan Menderes University Hospital will be included. The study will consist of two groups: 200 patients diagnosed with hemorrhoids and 200 patients with other non-hemorrhoidal benign proctologic conditions serving as controls. All participants will undergo routine clinical evaluation and demographic data collection. Cardiovascular surgeons will voluntarily perform physical examination and Doppler ultrasonography of the lower extremities to assess venous insufficiency and varicose veins. No experimental intervention or treatment will be applied. The study will not require any consumable materials and will not impose any additional financial burden on the hospital, patients, or the national health insurance system. The primary outcome is the prevalence of lower extremity venous insufficiency in patients with hemorrhoids compared with controls.

This study compares two minimally invasive treatments for varicose veins in the legs, specifically the great saphenous vein. Varicose veins can cause symptoms such as leg pain, swelling, and skin changes. One commonly used treatment is foam sclerotherapy, where a special foam is injected into the vein to close it. This method is simple and allows patients to return quickly to their daily activities, but sometimes the vein can reopen, requiring additional treatments. Another option is mechanochemical ablation, which combines a small device with a medication to close the vein. This method also allows for quick recovery and may have a lower chance of the vein reopening. In this study, 50 patients with varicose veins will be randomly assigned to receive one of these two treatments. Doctors will follow patients over time to evaluate: How well the treated vein stays closed Improvement in quality of life Pain during the procedure Possible complications All procedures are performed with local anesthesia, and additional small varicose veins are treated at the same time.

The purpose of this clinical trial is to know which is better to treat the branch vein at the same time or in stages during radiofrequency ablation. The main questions it aims to answer are: Does the patient who did not treat the branch vein in the first stage of operation need to intervene again? Are there any differences in patients' indexes between the two surgical strategies? Participants will: Radiofrequency ablation with or without foam sclerosing agent therapy One week, three months and six months after operation, go to the clinic for a reexamination. Record their symptoms

Lower extremity varicose veins (LEVV) are common among elderly patients and can cause leg heaviness, pain, and swelling. In some older adults, venous congestion may contribute to knee or peri-knee pain, which is often misattributed to degenerative joint disease alone. Evidence on whether varicose vein treatment can relieve knee pain in very elderly patients (aged 80 years or older) is limited. This prospective cohort study aims to evaluate the effectiveness and safety of endovenous ablation (EVA) for improving knee pain in elderly patients with symptomatic varicose veins. The study will include participants aged 80 years or older who present with both lower extremity varicose veins and knee joint pain. Eligible patients will undergo endovenous thermal ablation (radiofrequency or endovenous laser ablation) as the primary intervention. Participants will be assessed at baseline, 1 month, 3 months, 6 months, and 12 months after treatment. The primary outcome is the change in knee pain intensity measured by the Visual Analog Scale (VAS) from baseline to 6 months. Secondary outcomes include changes in knee joint function (assessed by the Western Ontario and McMaster Universities Osteoarthritis Index \[WOMAC\] or Knee Injury and Osteoarthritis Outcome Score \[KOOS\]), venous clinical severity score (VCSS), limb heaviness, quality of life (assessed by EQ-5D), and procedure-related complications. Safety will be evaluated by recording peri-procedural adverse events, including deep vein thrombosis, skin burns, nerve injury, and postoperative infection. The study will also analyze whether preexisting osteoarthritis, venous reflux severity, or body mass index (BMI) affect the magnitude of pain improvement. The hypothesis is that endovenous ablation improves knee pain in elderly patients by reducing venous congestion around the knee and improving venous return. This study will help clarify whether treating varicose veins can provide additional benefits for knee pain and mobility in patients aged 80 years and older.

This study will observe patients with lower limb varicose veins who also have knee pain. Many patients with varicose veins experience swelling, heaviness, or aching in the legs, and some also report pain in or around the knee. Previous studies suggest that venous reflux and poor circulation may increase discomfort in the knee, especially when knee osteoarthritis is present. The purpose of this study is to evaluate whether treatment of varicose veins with standard endovenous procedures can improve knee pain and function. Participants will undergo standard vein treatment as part of their clinical care. We will follow them for changes in knee pain, quality of life, and leg symptoms over time. This study does not assign patients to experimental interventions. Instead, it collects information before and after treatment to better understand the relationship between varicose veins and knee pain relief. Findings from this study may help doctors identify which patients are most likely to benefit from venous treatment in terms of both leg and knee symptoms.

This randomized, controlled, non-inferiority trial aims to compare the efficacy of two sclerosants used in the CLaCS (CryoLaser and CryoSclerotherapy) method for treating telangiectasias and reticular varicose veins. CLaCS is an advanced outpatient procedure that combines Nd\\:YAG laser treatment with sclerotherapy to enhance vein closure and cosmetic outcomes while minimizing side effects. The trial will compare the standard 70% glucose sclerosant with a novel 0.2% Aetoxysklerol (polidocanol) foam prepared using the VARIXIO system. Despite widespread use of CLaCS, no head-to-head studies currently exist comparing these two agents. This study aims to determine whether low-concentration Aetoxysklerol foam is non-inferior to 70% glucose in achieving effective telangiectasia elimination.

This study aims to systematically compare the clinical efficacy (venous closure rate and symptom relief rate), safety (perioperative and postoperative complications), and cost-effectiveness (direct medical costs) of domestic Xianruida radiofrequency catheter and imported Medtronic catheter in endovenous radiofrequency ablation for varicose veins through a single-center, prospective, non-inferiority randomized controlled trial.

Compression therapy is basic treatment for chronic venous disease (CVD) of the lower limbs. Numerous studies have demonstrated the efficacy and safety of compression therapy in relieving symptoms such as pain, venous edema, leg heaviness and fatigue, as well as accelerating the healing of venous ulcers. It has been established that сompression therapy is indicated for patients with both minimally expressed manifestations of CVD and severe forms of the disease. At the same only one study has been conducted to assess the correction of venous outflow from the lower limbs and pelvis in patients with pelvic varicose vein (PVV) and pelvic congestion syndrome (PCS). However, the incidence of this pathology ranges from 15 to 30% in the female population. The cost to the healthcare system of treating these patients in the United States exceeds $2 billion. To date, the options and indications for compression therapy in patients with concomitant PVV and CVD have not been defined. The rational use of compression in this cohort of patients may contribute to the improvement of effective conservative treatment. In addition, inappropriate prescription of compression to patients with pelvic venous disease (which can be observed in real clinical practice) may discredit this simple, effective and safe therapeutic method. In addition, the research devoted to the problem of compression treatment of PVV will contribute to the development of new special compression products aimed at accelerating venous outflow from the pelvic organs. It can be assumed that this will serve as a stimulus for obtaining new data on the therapeutic effects of compression and create conditions for the creation of new technological directions in the production of compression knitwear.

Objective: To investigate the clinical efficacy of ultrasound-guided radiofrequency ablation and microwave ablation in the treatment of primary saphenous varicose veins.

Objective: This study is a single-center prospective observational research that recorded patients' pain scores at four time points during surgery (puncture and catheter insertion, swelling fluid injection, microwave generator operation, and end of surgery). It analyzed the correlation between pain during microwave ablation treatment for great saphenous vein varicosities and factors such as age, gender, body mass index, volume of swelling fluid used, and others, in order to summarize and improve surgical details to reduce patients' intraoperative pain.
