wire entrapment
Procedural complication where guidewires become irretrievably stuck within vascular lesions during endovascular interventions.
Full Definition
Wire entrapment is a serious procedural complication that occurs when guidewires become mechanically trapped within arterial lesions, stent struts, or vessel bifurcations and cannot be withdrawn using conventional techniques. This complication can result from wire fracture, kinking, or entanglement with deployed devices or calcified plaque. Wire entrapment may compromise procedure completion, require additional interventional techniques for removal, or necessitate surgical extraction. Prevention involves careful wire selection, gentle manipulation techniques, and awareness of high-risk anatomical situations where entrapment is more likely to occur.
