Circumferential wrapping and clipping with temporalis fascia for treatment of unclippable intracranial aneurysms.
We utilized a clip-reinforced wrapping technique using temporalis fascia for treating unclippable aneurysms in 14 patients. Herein, we describe a modification of the clip- reinforced wrapping technique and report on the results. An appropriately sized strip of temporalis fascia is passed around the aneurysms with cuts made to accommodate perforating arteries. After applying fibrin glue, the aneurysm clip is positioned to secure the circumferential wrapping. Of the 14 patients, 4 (29%) were unclippable microbleb, 4 (29%) were wall defect, 3 (21%) were imperfect clipping due to the complexity of the aneurysm, 2 (14%) were bleb at the base of the aneurysm and 1 (7%) was a fusiform aneurysm. Multiple aneurysms were found in 6 (43%) patients and half (50%) of the 14 patients had MCA aneurysms. Postoperative angiography demonstrated no narrowing of parent arteries or enlargement of the aneurysms. No subsequent bleeding was observed during the 1 year follow-up period. These results suggest that circumferential wrapping-clipping with temporalis fascia and biological glue provides an alternative and safe method of treatment for unclippable intracranial aneurysms.
