[Analysis of 76 surgical procedures to create extra-intracranial microanastomoses].

Extraintracranial microanastomoses were created in 66 males and 16 females suffering from stenotic-occlusive changes in the major arteries of the head and brain which had caused cerebral circulatory disorders of various degree. The periods between the onset of the disease and the operation varied from 7 hours to 2 years. Twelve patients were operated on in the acute phase of cerebral ischemia. Postoperative improvement was noted in 90.8% of cases. Two patient died but their death was not caused by the operation that had been performed. Angiography and other methods of examination confirm functioning of the anastomosis.
