Abstract
The complication rate in varicose vein surgery has not been viewed separately for the sapheno-femoral and the saphenopopliteal junction. From 1.10.1988 to 31.12.99 we prospectively registered the major vascular and neural complication rate. A total of 31,838 ligations of the saphenofemoral junction and 6,152 ligations of the saphenopopliteal junction were performed. There were seven major vascular injuries (0.017 %) and three major neural injuries (0.0074 %). The specific risk at the saphenofemoral junction amounts to: major venous injury n = 4 (0.013 %) without development of a post-thrombotic syndrome (PTS); no arterial injury and no major neural injury. At the saphenopopliteal junction we found three major venous injuries (0.049 %) with development of PTS in all cases. There were three major neural injuries (0.049 %) with complete regeneration in two cases and one permanent paresis of digit V. Since operations on the saphenopopliteal junction show a higher risk of major vascular und major neural injury, flush ligation of the saphenopopliteal junction should not be forced in every case.
