Received: 8 Oct, 2008 Accepted: 11 Feb, 2009 Abstract Arteriovenous Malformation( AVM ) is one of the most common etiologies of subarachnoid hemorrhage. In the past, conventional angiography was the only way for the diagnosis of AVM but nowadays, using noninvasive devices such as MRA and recently TCD, the diagnosis of AVM is revaluated. This patient is a 19 year old man who was admitte...
متن کاملVasospasm after subarachnoid hemorrhage: utility of perfusion CT and CT angiography on diagnosis and management.
PURPOSE To evaluate the utility of perfusion CT (PCT) combined with CT angiography (CTA) for the diagnosis and management of vasospasm, by using conventional digital subtraction angiography (DSA) as the gold standard. METHODS We retrospectively identified 27 patients with acute subarachnoid hemorrhage who had undergone CTA/PCT, DSA, and transcranial Doppler (TCD) ultrasonography within a time...
متن کاملDiagnosing Vasospasm After Subarachnoid
Aneurysmal subarachnoid hemorrhage (A-SAH) has potentially devastating consequences acutely, sub-acutely and long term. The incidence of A-SAH varies widely among populations with up to a tenfold difference. Incidence ranges from 2.0 per 100,000 per year in China to 22.5 per 100,000 per year in Finland.1 One of the most feared complications in patients who survive the acute A-SAH is cerebral va...
متن کاملCurrent Controversies in the Prediction, Diagnosis, and Management of Cerebral Vasospasm: Where Do We Stand?
Aneurysmal subarachnoid hemorrhage occurs in approximately 30,000 persons in the United States each year. Around 30 percent of patients with aneurysmal subarachnoid hemorrhage suffer from cerebral ischemia and infarction due to cerebral vasospasm, a leading cause of treatable death and disability following aneurysmal subarachnoid hemorrhage. Methods used to predict, diagnose, and manage vasospa...
متن کاملCT perfusion-derived mean transit time predicts early mortality and delayed vasospasm after experimental subarachnoid hemorrhage.
BACKGROUND AND PURPOSE There are limited indicators available to predict cerebral vasospasm in patients with subarachnoid hemorrhage (SAH). The purpose of this study was to determine if CT perfusion-derived hemodynamic parameters are predictors of vasospasm severity and outcome after experimental SAH. MATERIALS AND METHODS SAH was induced in 25 New Zealand white rabbits. Cerebral blood flow (...
