Endovenous Approach to Recurrent Varicose Veins

Chapter 10 Endovenous Approach to Recurrent Varicose Veins




Historical Background


Recurrence rates of varicose veins of 20% are common, with rates as high as 70% at 10 years.13 Up to 25% of procedures for varicose veins are performed for recurrent disease,4 thus placing considerable demands on health care resources. It is important to note that recurrent varicose vein surgery carries a much greater morbidity risk to the patient than does primary surgery.3 This risk is reduced markedly with endovenous techniques.




Pearls and Pitfalls



Previous High Ligation and Stripping


All patients with recurrent varicose veins should be evaluated with CFDI. Usually findings include neovascularity in the groin from which one or more tributary veins are found to descend the thigh. The tributary may attach to another tributary, a perforator, or a remnant of the great saphenous vein (GSV) in the thigh or calf (Fig. 10-1). The reflux extends into dilated tributaries of the skin; these vessels bulge and are palpable. In most cases, our approach is to enter any straight incompetent axial venous segments deep to the skin with a micropuncture access kit. These kits usually contain 4-Fr microsheaths, through which we place a 400- or 600-µm-diameter laser fiber. Perivenous tumescent anesthesia is placed, and the vein or veins are ablated in the usual manner. Because tortuous incompetent venous segments below the level of the skin do not allow the passage of guidewires, these are treated with ultrasound-guided foam sclerotherapy (Fig. 10-2).
