Clip-grafts for aneurysm and small vessel surgery.

Abstract

✓ Analysis of the use of the clip-graft for intracranial aneurysms indicates that the clip-graft is chiefly applicable to internal carotid and anterior communicating artery aneurysms. The development of the right-angle clip holder has extended its use to anterior communicating artery aneurysms that project posteriorly or superiorly. The dangers of dissection in the septal region are discussed. With few exceptions, the clip-graft is not applicable to the vertebrobasilar system or middle cerebral artery trifurcation aneurysms, although it has been used for aneurysms arising from the trunk of the latter vessel.
