Persistent incompetent truncal veins should not be treated immediately.

Abstract

The traditional attitude for the treatment of chronic venous disorder is to systematically treat incompetent truncal veins. We wanted to evaluate the outcomes of not treating all incompetent truncal veins with regard to our experience of focusing the treatment to the varicose tributaries. Retrospective study on all procedures of surgical treatment consecutively performed for varicose veins by single phlebectomy with preservation of a refluxing great saphenous vein (GSV), according to the principles of the ambulatory selective varices ablation under local anesthesia (ASVAL) during four years of practice. The clinical and hemodynamic outcomes have been evaluated at eight days, one year, and once a year. We have included 1212 lower limbs (LLs) that underwent consecutive ASVAL procedures in 816 patients (611 women and 205 men) aged between 19 and 93 years (mean age 53.7 years). The CEAP Class C classification was C0-C1 = 0%; C2 = 85.6%; C3 = 5.4%; C4 = 7.8%; C5 = 0.7%; C6 = 0.7%. Symptoms were present in 854 cases (70.5%). A thrombosis of the GSV was diagnosed at eight days postoperative in 13 cases (1.1%). A total of 1010 LLs were followed after the first postoperative year (mean follow-up of 44.5 months). A secondary major procedure was done in 30 cases during the follow-up: a striping of the GSV in nine cases and a redo phlebectomy in 21 cases. The cumulative incidence of a persistent or recurrent GSV reflux, of a varicose recurrence, and of secondary major procedure at five years after life table analysis was 33.8%, 13%, and 4.5%, respectively. A GSV reflux extended above plus below the knee and multiple connections of the varicose tributaries to the GSV at the calf were associated with a varicose recurrence (respectively 66.7% versus 55.3% p < 0.05 and 46.7% versus 12.8% p < 0.05). A treatment limited to the varicose tributaries by phlebectomy is safe and efficient at midterm with preservation of the main veins of the superficial venous system. It can be performed in a large group of patients thanks to a proper exclusion of cases with advanced chronic venous disorder. Therefore, the systematic treatment of an incompetent truncal vein is not relevant in the majority of the cases.
