EndoVenous-assisted invaginated stripping of the great saphenous vein: A pilot and feasibility study.

Objective: By incorporating an endovascular component into Great Saphenous Vein stripping, EndoVenous-assisted Invaginated Stripping (EVIS) aims to make the procedure minimally invasive. A study was conducted to investigate the surgical intervention. Methods: Sketches and videos were used to illustrate the technical aspects of EVIS. A prospective cohort study included 20 patients with chronic venous insufficiency (CVI). Results: EVIS is performed as a day-surgery. Technical success was 100%, and no complications were recorded. The mean operative time was 45 minutes, intraoperative pain score was 4.8, post-operative pain was 2.5, 1.8, 1.2, 0.5 at 48 hours, 1, 4, and 12 weeks, respectively. The mean blood loss was 15 mL, and the mean length of the GSV strapped was 19 cm. The follow-up duplex showed a reduction in the diameter of the residual GSV stump. Conclusions: EVIS is a combination of standard techniques that may prove valuable in managing CVI. [ABSTRACT FROM AUTHOR]
