Aortic Runoff as a Sign of Intracranial Arteriovenous Malformation

Arteriovenous malformations (AVMs) associated with intracranial aneurysms are on uncommon condition.Twelve cases of AVMs associated with cerebral aneurysms were reported in a series of 180 AVMs (6.7%) over the last 17 years, six of these were in the posterior fossa. Most all showed a hemodynamic correlation between the AVM and the aneurysm.AVMs and aneurysms should be treated surgically in one operation, however if this is not possible, we should take care of the hemodynamic change induced by the operative procedure. In the case of aneurysm rupture or unknown origin of hemorrhage, the aneurysm should be treated prior to the AVM.With conservative therapy, we observed enlargement of the aneurysm size in one patient, however there was no incidence of rebleeding.

Introduction Arteriovenous malformation (AVM) excision is a challenge for neurosurgeons. There is always a high risk of intraoperative bleeding. It is not only because of the abnormal vessels in the AVM, but also due to the change in hemodynamics of the surrounding brain. As the surgery proceeds, surrounding brain becomes more hyperemic and may start bleeding.

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.
