Abstract
Injection compression treatment of the long saphenous vein with proximal incompetence can yield good results if two factors are taken into account: first, a reliable injection technique, executed over many years, and second, a suitable non-toxic sclerosant, which is sufficiently strong to close even the largest varicose veins. The investigation of 88 patients showed in nearly 100% of cases an obliteration of the sapheno-femoral junction and, after a follow-up period from 1 to 10 years, permanent closure of the sapheno-femoral junction in 91.2% was achieved. In using our technique we have never encountered intra-arterial or paravenous injections, nor have we noted deep vein thromboses or pulmonary embolisms.
