[Possibilities and limits of ambulatory operations in vascular surgery: demands and reality]. / Möglichkeiten und Grenzen ambulanter Operationen in der Gefässchirurgie: Anspruch und Realität.

The requirements for day-case a-v fistula surgery are an effective out-patient clinic, adequate surgical and anaesthesiological equipment and a thorough patient selection for the planned operation. For surgical reasons, only 87 cases (8.1%) out of the 1068 a-v fistula operations carried out had to be admitted to a ward. Nevertheless 35% of the patients were on a ward at the time of the operation for medical reasons. In case of an ideal co laboration between nephrologists and surgeons there should not be more than 10-25% of the dialysis patients in hospital at the time of a-v fistula surgery depending on the severity of their disease and the planned operation.

[Aneurysm of a persistent sciatic artery. Case report and review of the literature]. / Aneurysma einer persistierenden A. ischiadica. Fallbericht und Literaturübersicht.

A persistent sciatic artery results from lack of regression of the fetal arterial blood supply of the leg and is often combined with an abnormally developed superficial femoral artery. A rare case of bilateral persistent sciatic artery with unilateral thrombosed aneurysm of the right buttock was found. The right sciatic artery was completely developed and terminated in the popliteal artery, which showed thromboembolic occlusion. The right superficial femoral artery was hypoplastic and showed no connection with the popliteal artery. The left sciatic artery was incompletely developed, and the popliteal artery was fed by a normal superficial femoral artery. All of the 104 cases published of persistent sciatic artery were reviewed according to the degree of development, side localization, clinical signs and frequency of aneurysms, as well as the morphology of the ipsilateral superficial femoral artery.
