Role of CT Angiography in Detection of Extracranial Carotid and Vertebral Artery Disease in Patients With Acutely Ruptured Intracranial Aneurysms

Introduction : Computed tomography (CT) and CT angiography are standard imaging modalities for suspected acute intracerebral hemorrhage due to ruptured intracranial aneurysms. In this clinical setting, several protocols of computed may be implemented. The protocol is limited vessels. extended also include carotid vertebral arteries the aortic arch. Objective: To define role in detection extracranial artery disease significance method patients with hemorrhages Materials methods: study included 275 neurosurgical nontraumatic aneurysms who were treated Scientific Research Institute – Ochapovsky Regional Clinical Hospital No. 1 (Krasnodar, Russian Federation) from September 2017 August 2020. performed all patients. scanned area both (an arch-to-vertex angiogram) detect diseases such as stenoses, occlusions, tortuosity, hypoplasia. Results Atherosclerosis internal was diagnosed 95 (34.5% total number study). 13 (4.7%) these stenoses hemodynamically significant. We identified a high frequency tortuous (122 cases, 44.3%) hypoplasia (59 21.5%). congenital anomalies (however, not arteries) associated higher incidence unfavorable outcomes after endovascular treatment Conclusions optimal should focus on head neck (up arch). This shows rate concomitant arteries. These findings important planning successful performance
