Balloon-assisted coil placement in wide-necked cerebral aneurysms: preliminary clinical experience.

Author information

Department of Neurological Surgery, Kagawa Medical University, Kagawa.


Endovascular treatment of wide-necked cerebral aneurysms with Guglielmi detachable coils (GDCs) has been limited due to coil protrusion into the artery. Seven patients with wide-necked cerebral aneurysms were treated with GDCs with temporary balloon inflation for mechanical protection during coil placement. Transarterial embolization of the aneurysm with GDCs had failed due to coil protrusion into the parent artery. The use of simultaneous temporary balloon protection achieved more dense intra-aneurysmal coil packing, especially in the neck, without compromising the parent artery.
