Endovascular treatment of intracranial aneurysms: a minimally invasive approach with advantages for elderly patients

Abstract

An endovascular approach, embolizing intracranial aneurysms with electrolytically detachable coils, is a new minimally invasive treatment of aneurysms. Reviewing our experience with 13 patients aged 70 years or more, 12 patients were treated successfully. Over an average follow-up period of 8 months, there was only one death which might be attributed to an intracranial aneurysm. This compares favourably with mortality rates approaching 50% for either conservative or traditional surgical management of aneurysms presenting with subarachnoid haemorrhage in this age group. Coil embolization, avoiding craniotomy, may offer particular advantages in managing intracranial aneurysms in the elderly patient.
