Isolated Great Saphenous Vein Stripping for Treatment of Varicose Veins in Lower Limbs

2026年5月26日 更新者：Nelson Wolosker、Hospital Israelita Albert Einstein

Clinical Outcomes and Quality of Life Analysis After Concomitant or Sequential Varicose Vein Resection Following Great Saphenous Vein Stripping in Patients With Lower Limb Varicose Veins

The goal of this clinical trial is to compare two surgical approaches for treating varicose veins in the lower limbs in adults: performing varicose vein removal at the same time as great saphenous vein stripping (concomitant) versus performing great saphenous vein treatment alone.

The main questions it aims to answer are:

  • Do clinical outcomes differ between these approaches?
  • Does quality of life improve differently depending on which surgical approach is used?

Participants will:

  • Undergo great saphenous vein stripping for lower limb varicose veins with or without simultaneous varicose vein ressection
  • Be assigned to have varicose vein resection either at the same time or in a subsequent procedure
  • Complete quality of life assessments before and after surgery

研究衡量的是什么？

主要结果指标

结果测量
措施说明
大体时间
Quality of life and symptom improvement assessed by the Venous Clinical Severity Score (VCSS) following great saphenous vein stripping in patients with lower limb chronic venous insufficiency
大体时间：Changes from baseline at 2 and 6 months of follow-up
VCSS ranges from 0-30; higher scores indicate more severe venous disease
Changes from baseline at 2 and 6 months of follow-up
Quality of life and symptom improvement assessed by the VEINES-QoL/Sym questionnaire following great saphenous vein stripping in patients with lower limb chronic venous insufficiency
大体时间：Changes from baseline at 2 and 6 months of follow-up
Original VEINES-QoL/Sym converted to 0-100 scale; higher scores indicate better quality of life
Changes from baseline at 2 and 6 months of follow-up

次要结果测量

结果测量
大体时间
Change in the volume of varicose veins assessed by a standardized visual scoring system based on caliber and extent (score range 1-6 per vein, higher scores indicate greater burden) following isolated stripping of the great saphenous vein
大体时间：Change in the number and volume of varicose veins in the lower limbs 2 months after surgical treatment
Change in the number and volume of varicose veins in the lower limbs 2 months after surgical treatment
