Surgical treatment of frontopolar artery aneurysm: a case report

Abstract

The study objective is to describe the results of surgical treatment of a patient with frontopolar artery aneurysm rupture. Materials and methods. A 22-year-old female patient in grave condition (Hunt and Hess grade 3, Glasgow coma score 14) was admitted to the Department of Neurosurgery on day 5 after hemorrhage. The patient presented with headache, nausea, weakness, and stiff neck. However, no hemodynamic, respiratory, motor, or sensitive disorders were observed. Computed tomography of the brain revealed a 35 cm3 intracerebral hemorrhage in the projection of the interhemispheric fissure and frontal lobes without transverse or axial dislocation. Computed tomography angiography demonstrated a distal aneurysm of the right frontopolar artery. Results. The patient underwent emergency osteoplastic craniotomy in the right pterional region followed by aneurysm excision and removal of intracerebral hemorrhage. The postoperative period was uneventful (Glasgow outcome score 5). The patient was discharged on day 14 postoperatively with no signs of focal neurological deficit. Conclusion. Thorough preoperative examination of patients with lobar hemorrhages prevents severe complications during surgery, such as uncontrolled intraoperative bleeding.
