Revelation and Management of Distal Anterior Cerebral Artery Aneurysms

Abstract

Pericallosal aneurysms can affect any segment of the anterior cerebral artery distal to the anterior communicating artery. They represent relatively 9% of all intracranial aneurysms and are mainly revealed by a hemorrhagic stroke in different forms. This retrospective study reviewed all patients that received clipping for DACA aneurysms among all cases of brain aneurysms. 10 patients were included in this group and several parameters were evaluated. 60% of patients were female and their ages ranged from 44 to 78 years. 80% of candidates complained of headaches and 50% presented seizures clipping. 60% of patients presented an IPH at their first presentation while SAH was found in half of them. A good WFNS score was noticed and almost of patients (80 %) were graded I. Most of aneurysms (80%) were located at the pericallosal – callosomarginal junction. We had two cases (20%) with additional aneurysms in other localizations. All of them received microsurgical clipping. most of them had good short and long -term follow-ups. We had one death after several systemic complications. DACA aneurysms are revealed at a small size with the onset of cingular hematoma or SAH, especially in the interhemispheric cistern. This could affect the cognitive functions and is considered a determining factor in the patient’s quality of life. The surgical clipping is an effective and durable option for their management
