Modified buddy wire technique for coil embolization of posterior circulation aneurysms

摘要

In coil embolization of a posterior circulation aneurysm, tortuosity or a small vessel caliber frequently prevents placement of a guiding catheter in the vertebral artery. Even in such difficult situations, however, coil embolization is the only treatment option when the patient’s clinical condition is very poor, or the aneurysm is inaccessible by microsurgery.
