Prevalence of Ruptured Intracranial Aneurysms in A Tertiary Care Hospital of Nepal

Abstract

Introduction: Intracranial aneurysms affect 3-8 percent of the world’s population, with rupturedaneurysms being the most common cause of subarachnoid hemorrhage. The sensitivity of ComputedTomography Angiogram in diagnosing intracranial aneurysm is 97%. The aim of our study is to findout the prevalence of ruptured intracranial aneurysms among all the admitted cases encountered inour hospital.
 Methods: A descriptive cross-sectional study was done at Upendra Devkota Memorial NationalInstitute of Neurological and Allied Sciences from 2016 to 2018. Convenience sampling method wasdone. In order to detect the site and size of aneurysms16 slice Siemens Computed Tomography withComputed Tomography angiogram was used. Ethical approval was obtained from the InstitutionalReview Board at Upendra Devkota Memorial National Institute of Neurological and Allied Sciences.Based on demographic data and computed tomography angiography findings, various morphometricparameters along with demographic parameters were considered for the study.
 Results: Among 10,856 cases, prevalence of ruptured intracranial aneurysms were found in 42(0.386%) [Confidence Interval= 0.395 to 0.377]. Among 42 cases, Middle Cerebral Artery aneurysmwas present on 16 (39.02%) followed by Anterior Communicating Artery on 14 (34.14%), thenPosterior Communicating Artery on 5 (12.19%). The largest neck and dome size were seen in basilartip aneurysm with size of 11mm and 8mm respectively. The most common type was Fischer grade 4.
 Conclusions: The prevalence of ruptured intracranial aneursyms were found to be higher ascompared to the other international studies.

“…Intracranial aneurysm is a cerebral hemangiomatous protrusion of the intracranial arterial wall caused by abnormal localized enlargement of intracranial arterial vessels, with a high disability rate, mortality rate, and relatively sudden onset[ 1 , 2 ]. The main pathological features of intracranial aneurysm are subarachnoid hemorrhage.…”
