The sensitivity of Computed<br>Tomography Angiogram in diagnosing intracranial aneurysm is 97%. The aim of our study is to find<br>out the prevalence of ruptured intracranial aneurysms among all the admitted cases encountered in<br>our hospital.</p> <p><br><strong>Methods</strong>: A descriptive cross-sectional study was done at Upendra Devkota Memorial National<br>Institute of Neurological and Allied Sciences from 2016 to 2018. Convenience sampling method was<br>done. In order to detect the site and size of aneurysms16 slice Siemens Computed Tomography with<br>Computed Tomography angiogram was used. Ethical approval was obtained from the Institutional<br>Review Board at Upendra Devkota Memorial National Institute of Neurological and Allied Sciences.<br>Based on demographic data and computed tomography angiography findings, various morphometric<br>parameters along with demographic parameters were considered for the study.</p> <p><br><strong>Results</strong>: Among 10,856 cases, prevalence of ruptured intracranial aneurysms were found in 42<br>(0.386%) [Confidence Interval= 0.395 to 0.377]. Among 42 cases, Middle Cerebral Artery aneurysm<br>was present on 16 (39.02%) followed by Anterior Communicating Artery on 14 (34.14%), then<br>Posterior Communicating Artery on 5 (12.19%). The largest neck and dome size were seen in basilar<br>tip aneurysm with size of 11mm and 8mm respectively. The most common type was Fischer grade 4.</p> <p><br><strong>Conclusions</strong>: The prevalence of ruptured intracranial aneursyms were found to be higher as<br>compared to the other international studies.</p>}, number={217}, journal={Journal of Nepal Medical Association}, author={Thulung, Suraj and Aryal, Binit and Baniya, Aashish and Ranabhat, Kajan and Shrestha, Bibhusan Kalu}, year={2019}, month={Jun.} }
