The 'triangle' rubber dam interposition technique: preservation of the arteries around an aneurysm.

摘要

The authors describe an intraoperative technique in which a triangular rubber dam is inserted between the aneurysm and the perforating arteries. In this way, we can avoid obstruction of perforating arteries on application of a clip. This technique is especially useful for deep-seated aneurysms, such as basilar bifurcation aneurysms.
