VASCULAR NEUROSURGERY - ANEURYSMS, ARTERIOVENOUS-MALFORMATIONS, SUBARACHNOID HEMORRHAGE, AND INTRACRANIAL HEMORRHAGE

Cerebrovascular disease continues to be a major source of morbidity an d mortality in our aging population. Endovascular therapy for the trea tment of cerebral aneurysms and associated vasospasm is gaining credib ility, Some arteriovenous malformations considered inoperable in the p ast can now be successfully treated using multimodality therapy, Quant itative measurement of cerebral blood flow is helping to identify pati ents at risk of ischemic events and defining new guidelines for interv ention. New noninvasive imaging modalities may replace conventional an giography for surgical disease. Advances in technology continue to imp rove our ability to treat cerebrovascular disease prior to irreversibl e ischemic events.
