Snare Entrapment During EVAR Limb Cannulation Resulting in Open Conversion. A Rare Complication.

We present an unreported complication that occurred during an accidental loss of the ipsilateral limb's wire during EVAR. During an endovascular repair of an abdominal aortic aneurysm (EVAR), unintentional loss of the ipsilateral limb's wire during deployment and withdrawal of the endogaft's main body occurred. The snare's loops were entrapped while attempting to catch the wire through the limb. Multiple maneuvers were performed to detach the snare, but all were unsuccessful. We then performed a conversion to open repair. In conclusion, commercially available endografts should include standard radiopaque markers in the ipsilateral limb to facilitate retrograde cannulation. Retrieval via the snare should not be performed proximal to the gate of the limb.
