Wrapping of intracranial aneurysms with gauze sponge.

A gauze sponge wrapping method to prevent recurrent subarachnoid hemorrhage (SAH) after incomplete obliteration of intracranial aneurysm or a residual neck after clipping was developed and tested. The authors performed the gauze wrapping for aneurysms with incomplete obliteration by clipping alone, abnormal changes of the parent artery wall which had the possibility of regrowth or rerupture, and surgical difficulties. The residual neck of the aneurysm or the abnormal arterial wall was tightly and completely wrapped, including the parent artery, and cemented with plastic adhesive. Seventy-eight (22.3%) of 349 surgically treated aneurysms were treated by gauze wrapping (26 wrapping only, 52 clipping and wrapping). The incidence of complications such as infection, angiospasm, and normal pressure hydrocephalus, and the clinical outcome were not significantly different for the wrapping and non-wrapping groups. No recurrent SAH was observed in the wrapping group during 3 months to 8.5 years follow-up. These results suggest that wrapping with gauze sponge is useful in the treatment for ruptured aneurysms which cannot be totally obliterated.
