Subarachnoid hemorrhage: utility of cerebral catheter angiogram in patients with abnormal and normal CTCatheterCerebrospinal FluidEmergency RoomSubarachnoid HemorrhageLumbar PuncturePurpose: To determine the relationship between the presence and location of acute nontraumatic subarachnoid hemorrhage (SAH) ...
Patients with aortic coarctation are also predisposed to neurovascular complications such as intracranial hemorrhage, subarachnoid hemorrhage, and spinal hemorrhage [77,78,79]. Surgical correction of aortic coarctation is strongly recommended as early as possible, given the high mortality rate (up to 50...
Methods—Forty-one datasets of 26 patients (57.5 ± 10.8 years, 18 F) with subarachnoid hemorrhage and suspected cerebral vasospasm, who underwent VPCT and angiography within 6h, were included. Two neuroradiologists independently evaluated the presence and severity of vasospasm on perfusion maps on a...
Cerebral Angiography for Evaluation of Patients with CT Angiogram-Negative Subarachnoid Hemorrhage: An 11-Year Experience BACKGROUND AND PURPOSE:CT angiography is increasingly used to evaluate patients with nontraumatic subarachnoid hemorrhage given its high sensitivity for aneurysms. We investigated the yield...
Intracranial aneurysms in patients with subarachnoid hemorrhage: CT angiography as a primary examination tool for diagnosis–systematic review and meta-analysis [published correction appears in Radiology. 2011 Aug;260(2):612. van Dijk, M J [corrected to van Dijk, J M C]]. Radiology. 2011;258(...
The fate of patients with subarachnoid haemorrhage, an aneurysmal pattern of haemorrhage on CT and two or more negative angiographies is unknown. We studied the long-term outcome of patients with three negative angiograms (n = 15) and compared the pattern of hemorrhage of these patients with ...
P-2-208 - Evaluation of the circle of Willis with three-dimensional CT angiography in patients with subarachnoid hemorrhage Introduction: Three-dimensional CT angiography (3D-CTA) was performed immediately after the onset of aneurysmal subarachnoid hemorrhage in patients and the accuracy with which rupt...
Giant intracranial aneurysms are frequently observed as incidental findings on CT and angiograms obtained for purposes other than subarachnoid hemorrhage, such as slowly evolving nerve palsy or hemiparesis. Since giant aneurysms often thrombose, the CT scan may demonstrate a large aneurysmal volume than ...
It has been extended into the evaluation of patients with possible vasospasm after subarachnoid hemorrhage (SAH) [5] and for the evaluation of cerebrovascular reserve with acetazolamide challenge in patients with carotid artery stenosis who are potential candidates for bypass surgery or endovascular ...
