Abstract

Introduction:Intracranial hemorrhage (ICH) is divided into two traumatic and non-traumatic categories. The present study sought to investigate the anatomical properties of non-traumatic intracranial hemorrhage in Kerman, Iran.
Method:A total of 305 non-traumatic ICH cases were chosen in Shafa medical center. Data from patients’ files and CT scan images, including demographic factors and type of malformation, aneurysm size and shape, as well as the invovled location and artery were gathered and statistically analyzed.
Results:Most cases were 40-60 years old. SAH, ICH and SAH+IVH were 69.5%, 14.4 and 8.5% respectively. From all, 65.2% had arteriovenous malformation and following furthure assessment, aneurysm with 148 cases (74.4%) was the most frequent and 57.4% of aneurysm cases were located in the right hemisphere. In 14.9% of cases, multiple aneurysms were observed.
Conclusions: According to the results of this study, non-traumatic intracranial hemorrhages caused by arteriovenous malformation were in the shape of an aneurysm; an increase in age may result in higher probability of aneurysm occurence.
