title: Risk of intraoperative aneurysm clip slippage: a new experience with titanium clips.
abstract: Slippage of an aneurysm clip as a result of insufficient clip-closing force cannot be predicted, even when using force-testing devices. Descriptions of intraoperative clip slippages are rarely found in the literature. The authors summarize four unusual cases in which titanium aneurysm clips slipped by a scissorslike mechanism during surgery. They analyze the possible factors implicated in such a dangerous situation and discuss corrective choices.
