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 forcetesting 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.
