It is not an uncommon occurrence for an intracranial aneurysm to rupture while it is being exposed at craniotomy. When this occurs, the resulting furious bleeding seriously hampers the surgeon's attempts to ligate or clip the neck of the aneurysm. Bleeding from the ruptured aneurysm can be stopped by temporary occlusion of both common and both vertebral arteries, affording the surgeon a much better opportunity of bringing the lesion under control. With the patient under hypothermia, arrest of the cerebral circulation has been maintained in this way for periods up to 14 minutes without evidence of brain damage.

The occlusion may be achieved by closing arterial clamps previously placed on the exposed arteries in the neck or by exerting traction on a loop of tape encircling each artery and threaded through a catheter. Both methods are effective, but they have the disadvantage of requiring a separate manipulation to close or
