Background And Aim
This study aimed at analyzing the demographic characteristics of the patients with non-traumatic intracranial hemorrhage, their angiographic results and the correlation between computed tomography (CT) scan and angiography findings.
Methods and Materials/Patients: In a descriptive study, we retrospectively reviewed the records of the patients with non-traumatic intracranial hemorrhage based on their brain CT or lumbar puncture findings from 2011 to 2017. For all patients, four vessel catheter angiography via the femoral approach was performed in the Medical Imaging Center of Kermanshah University of Medical Sciences, Iran.
We investigated 143 cases with non-traumatic intracranial hemorrhage which was indicated in CT findings (91.61%) or lumbar puncture (8.39%). Of 143 patients, 64 (44.8%) were men and 79 (55.2%) women (mean age 53.7±12.1 years old). Moreover, 104(72.7%) patients had Subarachnoid Hemorrhage (SAH), 19(13.3%) of them had Intracranial Hemorrhage (ICH), 8(5.6%) ones had Intraventricular Hemorrhage (IVH) and 12(8.4%) patients had normal brain CT. There were 100 cases of aneurysm (69.93%), 13 cases of Arteriovenous Malformations (AVM) (9.09%), 28 cases with negative angiograms (19.58%), and 2 cases with other pathologies (1.4%). Seven (4.89%) cases of multiple aneurysms were also recorded. Of 13 patients with AVM, 8(61.5%) patients had AVM in parieto-occipital region, 2(15.4%) in temporal, 1(7.7%) in frontal region and 2(15.4%) had deep AVM. Two (1.4%) patients with SAH had dural AVF. Twenty-eight (19.6%) patients had negative angiogram, 22 cases of them had second angiography after one to two weeks. The most common positive finding in the second angiogram was Acom aneurysm (18.18%).
Aneurysms and AVMs are the most common causes of non-traumatic intracranial hemorrhage. The most common site of intracranial aneurysms is the circle of Willis. A second angiogram after one to two weeks is necessary in most patients with negative results in first angiography after non-traumatic intracranial hemorrhage.
