Brachial artery approach for transluminal angioplasty of the internal carotid artery.

One possible problem in internal carotid angioplasty is inaccessibility of the lesion due to elongation of the aortic arch, the brachiocephalic trunk, or the carotid artery itself. A new approach to performing angioplasty of the right or left internal carotid artery utilizing the brachial artery was used after failure of the transfemoral approach in 5 lesions (4 patients). The common carotid artery was cannulated with performed 5F catheters. Angioplasty was performed with a conventional balloon dilatation catheter. If required, a Wall stent was implanted to optimize the angiographic result. After failure of the conventional transfemoral technique, the brachial technique permitted successful angioplasty of the ipsilateral internal carotid artery in 4 lesions and the contralateral internal carotid artery in 1 lesion. In 1 patient, a stent was implanted. No complications occurred. The mean stenosis diameter decreased from 77.8 +/- 6.3% to 17.8 +/- 9.1%. Doppler sonography performed 4-6 months later showed no restenosis. The brachial artery approach seems to be a suitable alternative to the femoral technique.

[Management of an iliac artery aneurysm with percutaneous placement of a Dacron-nitinol vascular endoprosthesis]. / Versorgung eines Iliakal-Aneurysmas mit einer perkutan applizierbaren Dacron-Nitinol-Gefässendoprothese.

An iliac aneurysm developed after local lysis and balloon dilatation of the left iliofemoral arteries in a 66-year old male patient. This led to arterial embolism. A self-expanding Dacron-Nitinol vascular endoprosthesis was inserted without surgery. In this way, the aneurysm was isolated from the circulation.
