INTRODUCTION. Aneurysmal rupture has been responsible for up to 85% of subarachnoid hemorrhage of non-traumatic origin, which has produced high morbidity and mortality and high hospital costs, the timely diagnosis, the detail of the location and size of the aneurysm has been adequate, either invasive or expectant. OBJECTIVE. Analyze the behavior of a series of cases of broken and unruptured intracranial aneurysms in terms of size, location, sex and age. MATERIALS AND METHODS. Retrospective study of the unique clinical history of the radiological report of 155 patients diagnosed with intracranial aneurysm by brain panangiography with digital subtraction as a gold standard that improved image quality, at the Carlos Andrade Marín Specialties Hospital, January 2015 to August 2018. RESULTS. Of the 155 patients with a total of 204 intracranial aneurysms of which (122; 204), injured and (82; 204), not injured, 72,0% occurred in women. The highest rupture percentages according to their location were: posterior communicating artery 34,0%, middle cerebral artery 26,0% and anterior communicating artery 15,0%. As for non-accident aneurysms, the most frequent locations were: 33,0% mean brain artery, 23,0% posterior communicating artery and 12,0% carotid segment. 65,0% of aneurysms presented ruptures with diameters equal to or greater than 5 mm. The average age of diagnosis was 56 years range; 17 - 90. CONCLUSION. Analyzing the percentages of rupture behavior in terms of size and location of our cohort and comparing it with those referred in the reviewed bibliography, it was concluded that the behavior of aneurysmal rupture was different depending on the population region studied.
