Key result
Application of Yasargil titanium clips in broad-neck internal carotid artery aneurysms larger than 2 cm resulted in intraoperative scissorslike clip slippage in four cases, requiring additional clipping.

Highlights the rare but dangerous risk of intraoperative slippage of titanium aneurysm clips by a scissors-like mechanism.
May warrant caution with Yasargil clips in large broad-neck ICA aneurysms; hypothesis-generating for alternative techniques or designs.
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.

Nievas et al. (2000) conducted a case report in Internal carotid artery (ICA) aneurysm (n=4). Yasargil titanium clip was evaluated on Intraoperative clip slippage. Application of Yasargil titanium clips in broad-neck internal carotid artery aneurysms larger than 2 cm resulted in intraoperative scissorslike clip slippage in four cases, requiring additional clipping.
