ABSTRACT
Introduction Pericallosal artery (PA) aneurysms represent 2 to 9% of all intracranial aneurysms, and their management remains difficult. Objective The aim of the present study is to describe the case of an adult woman with subarachnoid hemorrhage and bilateral PA aneurysm in mirror position. Case Report A 46-year-old woman was referred to our institution 20 days after a sudden severe headache. She informed that she was treating her arterial hypertension irregularly, and consumed 20 cigarettes/day. The patient was neurologically intact at admission. A non-contrast computed tomography (CT) on the first day of the onset of the symptoms revealed hydrocephaly and subarachnoid hemorrhage (Fisher III). An angio-CT/digital subtraction arteriography showed bilateral PA aneurysms in mirror position. The patient was successfully treated with surgery via the right interhemispheric approach (because the surgeon is right-handed); the surgeon performed the proximal control with temporary clipping, and introduced an external ventricular drain at the end of the surgery. The patient was discharged on the fourth postoperative day without any additional neurological deficits or ventricular shunts. Conclusion Ruptured PA aneurysm is a surgically challenging aneurysm due to the many anatomical nuances and risk of rebleeding. However, the operativemanagement of ruptured bilateral PA aneurysms is feasible and effective.

Se realiza un estudio de 30 pacientes con aneurismas localizados en el complejo de la arteria cerebral anterior-arteria comunicante anterior (ACoA), operados en el Servicio de Neurocirugía del Hospital Universitario "Arnaldo Milián Castro", durante un período de 7 años. Se analizan variables tales como edad, sexo, estado neurológico preoperatorio, momento quirúrgico, complicaciones y estado al egreso. La mortalidad general fue del 10 por ciento(AU)
The authors carried out a study in 30 patients with aneurysms located in the anterior communicating artery-anterior cerebral complex (ACA-ACC), that were operated on at the Neurosurgery Service of "Arnaldo Milián Castro" Teaching Hospital, during a period of 7 years. Variables such as age, sex, preoperative neurologic state, surgical moment, complications and status on discharge were analyzed. General mortality was 10 percent(AU)
