Background: Subarachnoid hemorrhage (SAH) refers to bleeding that occurs primarily within the subarachnoid space, in between cases of spontaneous SAH and rupture of an intracranial saccular aneurysm accounts for approximately 85%.
Objectives: The aim of this study was to assess clinical presentation, risk factors and the etiology of subarachnoid hemorrhage in a sample of Egyptian patients, and also assess the outcome of endovascular management and complications.
Patients and Methods: The study was carried out on patients with SAH who were subjected to endovascular neuro-intervention unit in AL-Hussein University Hospital, including patients with SAH retrospectively from 2006 to 2018, and the newly diagnosed patients during 2019.
Results: During the period from May 2006 to May 2019, 560 patients with SAH has been admitted. 136 patients (24.2%) were excluded from the study as they were critically ill. Their Hunt and Hess score were 4 to 5. Also, another 51 has been excluded due to missed files or discharge against medical advice. The remaining 373 patients. 145 patients were angiographically free, Patients with aneurysm were 228 patients, 77 patients died before therapeutic endovascular treatment as they delayed due to financial troubles, The remaining patients were 151, The most common type of aneurysm between those patients was anterior communicating aneurysm (27.8%), then MCA aneurysm (17.8%), posterior communicating artery aneurysm (13.9%), para-ophthalmic artery aneurysm (6.6 %), basilar artery aneurysm (5.9%), posterior inferior cerebellar artery aneurysm (6.4%), supraclinoid carotid  artery aneurysm (3.1%), peri callossal artery aneurysm (3.3%), T carotid artery aneurysm (7.2%), superior cerebellar artery aneurysm (1.9%), inferior cerebellar artery aneurysm (2.6%) and multiple aneurysms (6.6%). The complications of endovascular treatment in studied patients occurred in 13 patients (3.4%) in the form of aneurysmal rupture, coil displacement, hydrocephalus and vessel rupture.
Conclusion: Cerebral catheter angiography is a safe, feasible and efficacious procedure. The new technique in the endovascular management of the cerebral aneurysm as balloon or stent assisted technique and flow diverter stent is greatly reducing the complication rate and making the outcome is very promising.
