Abstract
A forty-four-year-old man was seen because of transient ischemic at tacks in the vascular laboratory. In vestigations indicated a high-degree stenosis of the internal carotid artery (ICA). In the intravenous digital sub traction angiography it seemed to be a case of fibromuscular dysplasia. At operation the authors found an iso lated dissection of the ICA, which was responsible for the stenosis. This was confirmed by histologic findings. The ICA was anastomosed to the ex ternal carotid artery in end-to-end technique. The dissected part of the ICA was resected. This proceeding was possible, because an anastomosis free of tension could be performed owing to a poststenotic coiling of the ICA. The postoperative course was uncomplicated. The follow-up six months later showed a patent ICA in Doppler ultrasound examination and intravenous digital subtraction angi ography.
