Effectiveness and safety of ultrasound-guided foam sclerotherapy for recurrent varicose veins: immediate results.

Kakkos SK, et al. J Endovasc Ther. 2006.


PURPOSE: To evaluate the effectiveness and safety of ultrasound-guided foam sclerotherapy in treating recurrent varicose veins.

METHODS: Between July 2003 and January 2005, 38 outpatients (25 women; median age 59 years, interquartile range 53.5-66.0) with recurrent varicose veins in 45 legs were treated. Ultrasound was used to identify sites of reflux. The Tessari method was used to produce foam using 3% sodium tetradecyl sulphate; up to 6 mL of foam was injected per session under ultrasound control. Results are shown as median (interquartile range).

RESULTS: A single sclerotherapy session was adequate in 26 (58%) legs. In 87% of all legs, complete elimination of both varicose veins and all reflux points was achieved. A positive association between the amount of injected foam and CEAP class (r=0.45, p=0.002) and venous clinical severity score (r=0.37, p=0.012) was found. There was a trend for more sclerotherapy sessions [median 2 (1-2)] in legs with incomplete saphenofemoral junction/ great saphenous vein (GSV) ligation or accessory GSV (n=16) to achieve varicose vein ablation versus legs with other primary sites of reflux [median 1 (1-2), p=0.12]. There were no instances of deep vein thrombosis or systemic complications; superficial thrombophlebitis occurred in 6 (8.2%) of the 73 injection sessions. Legs with proximal reflux due to previous incomplete ligation or fed by an incompetent pelvic vein experienced superficial thrombophlebitis more frequently (4/12, 33%) than legs without proximal reflux [1/33 (3%); OR 16, 95% CI 1.6-164, p=0.014].

CONCLUSION: In most patients, ultrasound-guided foam sclerotherapy is a safe treatment for recurrent varicose veins, with an excellent immediate result. However, the presence of proximal reflux may decrease the immediate results and predispose to superficial thrombophlebitis.
