Abstract
Detachable coil embolization currently plays an essential role for patients with ruptured basilar artery aneurysms, even though it may have an unfavorable outcome and there may be some technical problems of embolization. We describe Guglielmi detachable coil (GDC) embolization for five ruptured lower-mid basilar trunk aneurysms, using a variety of techniques. The patients' ages ranged from 61 to 78 years; Hunt and Kosnik grade was distributed from 2 to 4, and three patients were found to have fenestrations of the lower basilar arteries. All patients underwent aneurysmal embolization at the subacute or chronic stage. The transfemoral route was used in three patients – one of whom, with a wide-necked aneurysm, was treated by the balloon remodeling technique. The transbrachial approach was chosen for the fourth patient, while vertebral artery origin exposure followed by a direct puncture was achieved in the fifth. All patients were assessed with 80–100 % aneurysmal obliteration. No patient re-bled after the embolization. Small cerebellar infarction, possibly due to embolism from the obliterated aneurysmal sac, occurred 11 days after the treatment. Of the five patients, four achieved a good recovery, and one became severely disabled. Ruptured basilar trunk aneurysms can be successfully treated with GDC embolization. In addition to the routine transfemoral route, the transbrachial route, direct vertebral artery puncture, and balloon remodeling technique are also useful for the embolization of this location of aneurysm.
