Evaluation of Nontraumatic Aneurysmal Subarachnoid Hemorrhage - A Retrospective Cross-sectional Analysis
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2018, Vol 3, Issue 6
Abstract
Introduction: Primary (nontraumatic) subarachnoid hemorrhage (SAH) is an important complication of intracranial aneurysms. Multiple intracranial aneurysms are discovered in 15% to 35% of patients with aneurysm who present with subarachnoid hemorrhage (SAH). Increased age and female sex have an increased incidence of SAH patients with multiple aneurysms. Objective: This study was undertaken to analyse and evaluate the frequency and risk factors of nontraumatic aneurysmal subarachnoid hemorrhage using conventional CT angiography. Materials and Methods: The present study was a 2-year cross-sectional study, conducted on 350 patients with primary SAH, admitted in the wards and intensive care units of S.C.B Medical College and Ashwini hospital, Cuttack, Odisha, India during the period from January 2016 to December 2017. Results: In this retrospective cross sectional study we analysed 87 patients presented with spontaneous subarachnoid hemorrhage. Intracranial aneurysms are more common in female sex and in older age group. In male patients the aneurysms are more commonly seen on left side while in female patients it is seen more commonly on right side but overall it is observed more commonly on right side. Among the male patients aneurysms are more commonly located at Anterior communicating artery while in female patients it is more commonly detected at Posterior communicating artery. Conclusion: Subarachnoid hemorrhage is a grave complication of intracranial aneurysm. Female sex by itself is also associated with an increased incidence of multiple aneurysms. Eary CT angiographic study can locate exact location and size of aneurysm so that early intervention can be given. It appears likely that morphological risk stratification of intracranial aneurysms must at some point involve greater predictive power than that available with aneurysm size alone.
