Background: Spontaneous subarachnoid hemorrhage (SAH) is one of the most common and acute cerebrovascular events. The cause of this bleeding is often brain aneurysms or arteriovenous malformations (AVM). Co-incidence of these two vascular lesions is associated with an increased risk of cerebral hemorrhage. The purpose of the current study is to investigate the prevalence of cerebral aneurysm along with AVM in patients with spontaneous SAH based on computed tomography (CT) angiographic findings.
Methods: In this cross-sectional and retrospective research, 122 patients were studied. SAH was confirmed based on the results of the CT scan or lumbar puncture. Causes such as coagulation disorders and trauma were considered as the exclusion criteria. Vascular lesions have been investigated as a possible cause of SAH using CT angiography.
Findings: The results of the CT angiography images indicated the prevalence of arterial aneurysm in 18 patients (14.7%), AVM in 11 patients (9%), and simultaneous aneurysm and AVM in 4 patients (3.3%). In addition, there was a significant correlation between the presence of vascular lesions and intraventricular and intraparenchymal hemorrhage.
Conclusion: CT angiography results showed a co-incidence of aneurysm and AVM in 3.3% of cases. Also, cerebral vascular lesions are associated with higher degrees of cerebral hemorrhage and multiply the possibility of intraventricular and intraparenchymal bleeding. Awareness of the prevalence of this co-incidence is essential for timely diagnosis and choosing the appropriate therapeutic approach in these patients.
