Stab Avulsion up to Date

Abstract

Stab avulsion is an operative procedure for the tributary veins of varicose veins that is performed not only to improve the cosmetic result, but also to improve the symptoms and long-term result of the surgery, such as the recurrence rate and the frequency of the need for second-stage procedure. In this article, the operative process of stab avulsion is explained in detail. First of all, large amount of anesthetic solution, which mostly consists of saline with 0.1% lidocaine, is infiltrated around the preoperatively targeted vein. Then, an incision is made with an 18-gage needle or a common number 11 scalpel which are ideal tools for making 2 mm incision. A hook is inserted from the incision and the targeted vein is identified by being put between the hook and the fingers. After hooking the vein, it is separated from the surrounding tissue by shaking not the vein but the surrounding tissue gently. And the separated vein is easily exposed out of the incision. The exposed vein is hold with forceps. After looking over the direction and the branches of the vein, the vein is taken out not by pulling the vein but by shaking the surrounding tissue. There are few and slight complications which are directly concerned with stab avulsion, such as bleeding, nerve disturbance, infection and so on.
