Feasibility Study of Ultrasound-guided Functional Remodeling of Lower Extremity Superficial Venous Valve
Varicose Veins of Lower Limb
About this trial
This is an interventional treatment trial for Varicose Veins of Lower Limb focused on measuring Varicose veins in the lower extremities, Ultrasonic guidance, venous valve of Lower limb
Eligibility Criteria
Inclusion Criteria: Age 18-80, gender unlimited CEAP grading was C2-C5 patients The patient was clinically diagnosed as a primary varicose great saphenous vein of lower extremity, and the ultrasound findings were great saphenous vein valve insufficiency (complete structure, normal shape, enlarged valve ring, Duration of reflux >0.5s), only unilateral varicose great saphenous vein was treated this time Exclusion Criteria: Patients with target vessel diameter < 3mm The final valve of the great saphenous vein was not clear or lost its normal shape on ultrasound Patients with deep vein valvular insufficiency The presence of thrombus or thrombophlebitis in the main trunk of great cryptic skin Target diseased blood vessel had previously received surgical treatment Patients with deep vein thrombosis or history of pulmonary distension embolism Patients with active implants such as pacemakers or ICDs Patients with severe abnormal liver and kidney function (more than three times the normal value) Patients with non-primary varicose veins caused by post-deep vein thrombosis syndrome, Cockett syndrome (iliac vein compression syndrome), KT syndrome (venous malformation hypertrophy syndrome >, arteriovenous sputum, etc Any serious or uncontrolled systemic disease (including poorly medicated hypertension, diabetes, and diseases with active bleeding signs or severe coagulopathy) Patients with diseases that may make treatment and evaluation difficult (e.g., malignant arsine tumor, acute infectious diseases, sepsis, systemic intolerability of surgery, life expectancy less than 12 months, etc.) Pregnant and lactating women, or those who planned to have children during the study period Patients who have participated in clinical trials of other drugs or medical devices within the last 3 months Anesthetist and other patients were deemed unsuitable for the study
