Despite satisfactory preoperative angiographic demonstration of intracranial aneurysms, the surgeon is often confronted at operation with lesions that are unsuitable for clipping or ligating. In the experience of the authors, a rapidhardening silicone rubber preparation has served to provide an immediately effective means of confining and reinforcing the walls of certain of these lesions. The plastic barrier formed by this material envelops the aneurysm without interfering with the patency of parent vessels, thus obviating the circulatory deficits imposed by trapping measures. Three cases are presented, illustrating the techniques and principles involved.
