Computed Tomographic Angiography versus Digital Subtraction Angiography for the Diagnosis and Early Treatment of Ruptured Intracranial Aneurysms

Abstract

It is possible to proceed to ruptured aneurysm repair entirely on the basis of good-quality CTA studies that demonstrate an aneurysm consistent with the pattern of bleeding observed on plain computed tomography (48% of the patients in this series and most common middle cerebral artery aneurysms). However, detection of small unruptured aneurysms in patients with multiple lesions remains a problem.
