Abstract

PURPOSE: The main factor limiting endovascular treatment of intracranial aneurysms is the shape of the a-neurysmal sac, especially the width of the neck. We describe an early experience and technical aspects of treating wide-necked cerebral aneurysm using a Guglielmi detachable coil (GDC) and simultaneous application of a temporary balloon. MATERIALS AND METHODS: Four cases of unruptured wide-necked cerebral aneurysm were treated with GDC, with simultaneous application of a temporary balloon. Patients were aged between 29 and 49 years. On admission, clinical presentation was subarachnoid hemorrhage (SAH) in all cases. Hunt and Hess grade was II in two cases, III in one case, and traumatic SAH in one case. In all patients angiography revealed an asymptomatic a-neurysm after rupture of another aneurysm or traumatic SAH. The aneurysms were occluded with GDC-10, and a Cirrus balloon occlusion system was used simultaneously. All procedures were performed under endo-tracheal general anesthesia and systemic heparinization. RESULTS: All cases were treated successfully, without parent artery compromise. The occlusion rate at the end of the procedure was total in three cases and subtotal in one. In one case a heparin-related hematoma occurred during post-procedural treatment and the patient eventually expired. One patient underwent follow-up angiography after 6 months, and the coil was not changed. CONCLUSION: An aneurysm may not be completely occluded, but with regard to coil compaction and parent artery preservation, the technique is an attractive alternative.
