title: The surgical management of extracranial cerebrovascular occlusive disease: a review of 200 consecutive surgical cases.
abstract: The role of surgery in the treatment of extracranial cerebrovascular disease is essentially a prophylactic one but it should be borne in mind that apart from preventing stroke, such procedures will or should eliminate symptoms. The authors believe that every patient suffering from cerebrovascular insufficiency should be thoroughly evaluated for extracranial cerebrovascular occlusive disease and that arteriograms should be performed on all patients who could be expected to be candidates for surgery. The various indications for surgery have been discussed. The authors believe that people who have severe bilateral disease and who are of an advanced age are probably in a higher risk group. They also believe that surgery should not be offered to people who have a complete stroke and who are in semi-coma or coma, no matter how rapidly they may be transferred to the operating theatre. The authors firmly believe that intra-operative E.E.G. monitoring is an important adjunct to the safe surgical treatment of lesions of the carotid bifurcation, not only to indicate when shunting is necessary but also to indicate how well that shunt is functioning. In spite of the frequent presence of associated heart disease, hypertension and other vascular lesions, operation can be offered with confidence to suitable candidates. Elimination of symptoms can be expected in over 90% of cases. Only one patient has suffered a stroke since leaving hospital and this occurred because of occlusion in his internal carotid artery which was not operated on. Apart from patient selection, the factors which have contributed to the authors' low morbidity and mortality have been the use of intra-operative E.E.G. monitoring, intra-operative heparinisation and the availability of excellent angiographic studies.
