In the course of an infection with human immunodeficiency virus, a large variety of complications affecting all organ systems can occur. However, complications affecting the vascular system demanding surgical intervention are rare. In the case presented we report a 67-year-old HIV-seropositive patient who underwent surgery for a huge abscess in the thigh. Intraoperatively unexpectedly we found a mycotic aneurysm of the femoral superficial artery and the causactive bacterium proved to be Salmonella enteritidis. Because of the rising number of HIV-infected patients we suspect that the amount of complications involving the vascular system and demanding surgical intervention will also increase. Therefore, when diagnosing and deciding on therapy for patients with AIDS, the physician must be aware that vascular complications due as a result of HIV infection might occur more frequently in the future.

We report 96 patients (107 legs) with recurrence after varicose vein surgery. We define a recurrent varicose vein as a new transfascial insufficiency after incomplete interruption of the saphenofemoral as well as popliteal junction with reflux in the epifascial venous system. 92 patients underwent external primary surgery. Morphologically an insufficient high ligation of the V. saphena magna (Moszkowicz's operation) led in 30 cases to a recurrent varicose vein. In 47 cases an incomplete isolated, in 29 cases an incomplete saphenofemoral ligation during a Babcock procedure and in one case an incomplete saphenopopliteal ligation for V. saphena parva insufficiency were the reasons for the recurrence. As recurrent surgery we performed 106 ligations of the saphenofemoral junction. In 38 of these cases an isolated saphenofemoral ligation and in 68 cases an additional stage-adjusted ligation of the V. saphena magna were carried out. In one case of recurrent saphenopopliteal insufficiency a repeated ligation of the V. saphena parva was performed. The recurrence is an avoidable complication of a not perfect primary surgery. The main cause is an inadequate access with incomplete saphenofemoral or -popliteal ligation.
