Additional value of 3D rotational angiography in angiographically negative aneurysmal subarachnoid hemorrhage: how negative is negative?
BACKGROUND AND PURPOSE In some patients with nonperimesencephalic nontraumatic subarachnoid hemorrhage (aneurysmal SAH), no aneurysm can be found on digital subtraction angiography (DSA), and repeat DSA is advocated. 3D rotational angiography (3DRA) is considered superior to DSA in the detection of small intracranial aneurysms. In this study, we assessed the additional diagnostic value of 3DRA ...
متن کاملSubarachnoid Hemorrhage with Negative Baseline Digital Subtraction Angiography: Is Repeat Digital Subtraction Angiography Necessary?
INTRODUCTION Patients with negative initial digital subtraction angiography (DSA) are at significant risk for re-bleeding, which can lead to severe disability and death. The purpose of this study was to evaluate the necessity of repeat DSA in subgroups of patients with subarachnoid hemorrhage (SAH) with negative initial DSA. METHODS A total of 904 spontaneous SAH patients were admitted to our...
متن کاملDifferent clinical characteristics between perimesencephalic subarachnoid hemorrhage and diffuse subarachnoid hemorrhage with negative initial angiography.
AIM The purpose of this study was to compare the different clinical features, outcome and treatment strategies in patients with perimesencephalic SAH (p-SAH) and diffuse SAH (d-SAH). MATERIAL AND METHODS 83 patients with spontaneous SAH and negative initial cerebral angiography were retrospectively reviewed. RESULTS There were 49 patients with p-SAH and 34 with d-SAH. The patients with d-SA...
متن کاملThe Importance of Catheter Angiography in Computed Tomography Angiography-Negative Subarachnoid Hemorrhage
Computed tomography angiography (CTA) has become an effective tool in the evaluation of patients with subarachnoid hemorrhage (SAH), but it still has limitations. Up to 15% of non-traumatic SAH cases are negative on CTA. The benefits of catheter angiography in the evaluation of certain cases of CTA-negative SAH have been previously demonstrated. Here, we present the case of a 48-year-old female...
متن کاملNegative CT angiography findings in patients with spontaneous subarachnoid hemorrhage: When is digital subtraction angiography still needed?
BACKGROUND AND PURPOSE CTA is becoming the frontline modality to reveal aneurysms in patients with SAH. However, in about 20% of SAH patients no aneurysm is found. In these cases, intra-arterial DSA is still performed. Our aim was to evaluate whether negative findings on CTA can reliably exclude aneurysms in patients with acute SAH. MATERIALS AND METHODS We conducted a retrospective analysis ...
