Comparison of the Role of CT Angiography and DSA in Detecting Aneurysms in Cases with Spontaneous Subarachnoid Hemorrhage
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 8
Abstract
Background and Purpose: Subarachnoid hemorrhage (SAH) due to rupture of aneurysms is one of the most alarming and catastrophic condition as it can cause significant morbidity and mortality and poses a formidable challenge both in its diagnosis and management. The present study is to compare the role of computed tomography (CT) angiography in detecting ruptured aneurysm with spontaneous SAH and the role of digital subtraction angiography (DSA). Materials and Methods: During the period of 5 years from September 2012 to August 2017, patients presented with spontaneous SAH were studied. These patients underwent both 3 D - computerized tomography angiography (CTA) and 4 - vessel cerebral DSA. CTA and DSA findings were evaluated and compared in terms of the existence of aneurysm, size, shape, number, location, and major vessel branching. Results: Total 32 cases only 17 cases were positive with 19 aneurysms, 2 patients having 2 aneurysms each and 15 were negative. CTA has sensitivity of 89% in imaging aneurysms and in 86% of negative CTA cases DSA also negative for delineating aneurysm. Conclusion: CTA is a good procedure with a sensitivity of 89% in the detection and delineation of cerebral aneurysms. Owing to the lower specificity of CTA in some cases, DSA remains the gold standard in evaluating patients with cerebral aneurysms. In complex aneurysms, DSA supplements CTA images in planning their management.
