Balloon-Assisted Guglielmi Detachable Coil Placement in Wide-Necked Internal Carotid-Ophthalmic Aneurysms: A Report of Four Cases

Abstract

We present an endovascular technique for treating wide-necked ophthalmic aneurysms using Guglielmi detachable coils with simultaneous temporary balloon protection. Four illustrative cases of wide-necked ophthalmic aneurysms treated with Guglielmi detachable coils and a temporary balloon are presented. By blocking the parent artery with a non-detachable balloon, the coils could be safely placed in these aneurysms without herniation when the balloon was deflated. All patients exhibited embolic manifestations after the procedure, and the use of simultaneous temporary balloon protection allowed more dense intra-aneurysmal coil packing. Although this technique requires manipulation of a second microcatheter and balloon, which increases its technical difficulties and is a higher-risk procedure than the standard coil placement, it can be used for patients who are not candidates for surgery. Long-term follow-up is needed to determine the final outcome of aneurysms treated by this technique.
