Frequency of ruptured cerebral aneurysms as a cause of intracerebral bleed.

Abstract

Objective: To determine the frequency of ruptured aneurysms in patients with intracerebral bleed presenting to Shifa International Hospital Islamabad. Study Design: Cross sectional study. Setting: Department of Radiology, Shifa International Hospital Islamabad. Period: September’25 to February’26. Methods: 140 Patients aged from 18 to 70 years of either gender and presentation with Intracerebral bleeding whereas all cases with history of head trauma and craniotomy were excluded from the study. Every patient undergo a CT scan, and the presence of ruptured aneurysms (CT noncontrast shows hemorrhage prominent at well-defined round, slightly hyper attenuating lesion) were documented. Results: Of 140 patients (61.4%) were aged above 50 years, while 38.6% were 50 years or younger. Females predominated (55.0%) compared to males (45.0%). Overall, 46 patients (32.9%) were found to have ruptured aneurysms, while 94 (67.1%) had unruptured aneurysms. Regarding the location of aneurysms, hemorrhagic stroke (HS) was the most frequent presentation (50.7%), followed by subarachnoid hemorrhage (SAH) in 30.7% and combined SAH + HS in 18.6% of cases. Conclusion: We concluded that aneurysm rupture is a multifactorial process governed by anatomic factors (size, location, multiplicity) and patient-specific vessel vulnerability rather than by single metabolic parameters.
