Surgical treatment of cerebral ischaemia caused by cervical arterial lesions due to Takayasu’s arteritis: Preliminary results of 49 cases

Abstract

When cerebral perfusion is jeopardized, a definitive corrective procedure is advised at a time when the patient is in a relatively stable condition. Percutaneous transluminal angioplasty is the first choice although the recurrence rate is very high, and complications such as arterial rupture and thrombosis formation are serious. Patients with occlusive lesions of all four cervical arteries usually have severe cerebral ischaemia and their distal runoff is usually unable to be visualized on angiography. But it was found that in 95% of cases the internal carotid artery is still patent (confirmed by exploration), therefore an ascending aorta-to-carotid bypass is feasible in most instances. Unfortunately, cerebral re-perfusion syndrome is a serious unresolved problem.
