[Major vascular and neural complications in varicose vein surgery. Prospective documentation of complication rate in surgery of the V. saphena magna and V. saphena parva]. / Major-Komplikationen am Gefäss- und Nervensystem in der Varicenchirurgie. Prospektive Dokumentation des Operationsrisikos bei der V. saphena magna- und V. saphena parva-Operation.

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 postthrombotic 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.
