Venous angiomata: treatment with sclerosant foam.
Venous angiomata, or venous malformations, are often present at birth, although they may not be evident until later. They consist of a spongy tangle of veins, and these lesions usually vary in size. Treatment of venous angiomata is often requested for cosmetic reasons, but painful ulcerations, nerve compression, functional disability can command care. This presentation describes management using sclerosant foam as the treating agent. During a 30-month period ending March 2004, 1,321 patients were investigated for venous disorders at the Vein Institute of La Jolla. Fourteen (incidence 1%) were found to have venous angiomata (: nine women). The age range was 15-76 years (mean 30.8 +/- 18.6). Lesions were classified by the Hamburg system and were primarily venous, extratruncular in 12 patients and combined extratruncular and truncular in two patients. Eight patients, three males, had manifestations of lower extremity Klippel-Trenaunay (syndrome; six had only venous angiomas. Only 10 of the 14 patients were treated. All patients were studied by Doppler duplex examination. Selected lesions were chosen for helical computed tomographic studies. Magnetic resonance venography was also used to image the lesions, define the deep circulation, note connections with normal circulation, identify vessels for therapeutic access, and determine infiltration of the lesion into adjacent soft tissue. Foam was produced by the Tessari two syringes one three-way stopcock teclinique, with the air to Polidocanol ratio being 4 or 5 to 1. This was used at 1% or 2% concentration, specific for each patient. The SonoSite 190 plus Duplex Doppler was used for ultrasound guidance, whenever deep access was required and to monitor progress and effects of treatment. A goal was set for each patient before treatment was begun. Ten patients were treated, and four await treatment. The mean number of treatments was 3.6 +/- 2.8 (range 1-10). A primary goal of pain-free healing was set in patients with nonhealing, painful ulceration or symptomatic varicose veins. This was achieved in all treated patients. Cosmetically, all of the patients were improved, and symptomatic patients were relieved of pain. The single complication was formation of a cutaneous ulcer following injection of telangiectasias. Sclerosant foam is a satisfactory tool to use in treating venous angiomata including the Klippel-Trenaunay syndrome. Use of foam sclerotherapy in this experience has proven the technique to be effective, essentially pain-free, and durable in the short term.
