Analysis of 274 Omniflow Vascular Prostheses implanted over an eight-year period.

Background: Polytetrafluoroethylene (PTFE), dacron, and, more recently, collagen prostheses are finding increasing use for femoropopliteal reconstruction when a suitable vein is not available. The main factors to be considered when choosing a prosthesis are patency, susceptibility to infection and formation of aneurysms.

Methods: Sheep collagen prostheses were implanted on 274 occasions in the femoropopliteal or crural regions.

Posttraumatic extracranial aneurysm of the internal carotid artery: combined endovascular treatment with coils and stents.

We report a case of a posttraumatic extracranial pseudoaneurysm of the internal carotid artery that was treated successfully via embolization with Guglielmi detachable coils and placement of a Wallstent after surgical repair failed.

[Femoropopliteal vascular replacement: vein, ePTFE or ovine collagen?].

In an eight year-period from 1988 to 1995 653 femoropopliteal and femorocrural bypasses were performed. 347 above-knee reconstructions 206 below-knee reconstructions and at last 100 femorocrural bypasses were analysed. The cumulative patency rate after a follow up of three years for above-knee vein bypasses was 90%, patency rate for PTFE grafts in the same period was 52%, for ovine collagen grafts 56%.

[Local vascular complications after iatrogenic femoral artery puncture].

Over a period of 5 years 81 vascular complications after 15,460 catheterizations of the femoral artery for diagnostic (n = 11,883) or therapeutic (n = 3577) procedures were registered. The following complications were observed in declining frequency: 1. False aneurysm (n = 65), 2.

Diagnosis and treatment of carotid body tumors.

Carotid body tumors are rare although they must always remain part of the differential diagnosis of a neck mass. Sonography as the screening method of choice followed by angiography determines the diagnosis. In 11 patients 12 carotid body tumors were extirpated.
