Abstract: 

Background: Considering the high morbidity and mortality, evaluation of different aspects of subarachnoid hemorrhage (SAH) can be effective in improving the disease consequences. This article evaluates the angiographic findings and some epidemiological characteristics of in Iran.
Material and Methods: In an observational study on 580 SAH Iranian cases, we reviewed the information of SAH patients in whom the disease was proved with brain CT scan and/or LP. In all patients, standard subtraction brain angiography had been done; including AP, oblique and lateral views. In vertebrobasilar arteries, AP and lateral views was done.
Results: Sixty percent of all patients were male. About sixty percent of patients were 30-60 years old. Angiographic findings were as follows: 136 (23.4 %) Aneurysm, 82(14.1 %) AVM, 325 (56%) normal angiography and 37(6.3%) patients had other problems. Mean age of aneurismal patients were 46 years old and %59 were male. Over ally, 149 aneurysms were seen, meaning that 13 patients had two aneurysms. Sixteen (10.7%) aneurysms located in posterior circulation, and 133 (89.3%) located in anterior circulation. Fifty (33.6%) aneurysms were located in ACA 46(31%) IN
ICA 37 (24.8%) in MCA (17% of total aneurysms located in P.Comm.A), 10 (6.7%) in vertebral artery and 2(1.3%) in PCA.

Conclusion: High prevalence of disease in comparison to other studies could be due to relatively high exposure of men to some risk factors such as smoking or due to high percentage of men in this study. Lower P.Comm A aneurysms is an interesting finding that could help us in better understanding of pathophysiologic mechanisms of disease and may has an implication in diagnosis and of patients. High percentage of normal angiography can result from doing the procedure during vasospasm, use of high osmolar contrast media or lack of full angiographic views.
