S35. Surgery of Cerebral Aneurysm and Arteriovenous Malformation

Abstract

artery in one-stage should not be done. All other patients showed good recoveries. Four cases of intracranial arteriovenous malformation were operated on, but the total extirpation of angiomatous portion was very difficult. Hazards were met with , chiefly in finding out afferent arteria. Serial angiography may be indispensable to demonstrate afferent and efferent vessels precisely. Non-traumatic intracerebral hematoma was found unexpectedly in 3 cases during operation under the diagnosis of brain tumor. This experience suggests that if the angiography in early stage following the stroke becomes more common, more patients of intracranal bleeding can be favored with surgery.
