ABSTRACT

Introduction. Intracranial carotid artery bifurcation aneurysms are infrequent but its clinical behavior, high risk of bleeding and complex anatomic relationships of the sac permit to consider these lesions as a challenge cases. Patients and methods. 497 patients harboring intracranial aneurysms were operated on at Manuel Ascunce Domenech Hospital, Camagüey, Cuba between January 1982 to august 2001. We utilized microsurgical procedures, optical magnification, specialized neuroanesthesia and Intensive Care Unit postoperatory following. All patients were evaluated clinically with World Federation Neurological Surgeon Scale and Glasgow Outcome Scale. Results. There were 16 patients with intracranial carotid artery bifurcation aneuryms (3.2 %). 12 patients were under 40 years and 50% were between 16 and 30 years old. All patients present intracranial bleeding. There was 87.5% of total or partial recuperation. There was one death only. Postoperative deficit were observed at 44% but 31% disappeared thee month later. Discusión. Intracranial carotid artery bifurcation aneurysms are complex anatomoclinical lesions. Clinically, we observed high tendency to bleed and multiplicity. Anatomically, these sacs have complex arterial retionship that difficult dissection and clipping. They have frequent postoperative morbidity. Multiple or bilateral aneurysmal sacs will be clipped by one surgical procedure.
