EVAR Technical Tip – Confirmation of Contralateral Limb Gate Cannulation Using a Moulding Balloon

摘要

Introduction: Accurate confirmation of cannulation of the shorter contralateral limb gate of an abdominal aortic endograft can be challenging. Catheter angiogram may not exclude all possible errors. Report: Accurate contralateral cannulation can be confirmed by insertion of a moulding balloon over a stiff wire and gentle inflation of the moulding balloon across the contralateral gate of the main body component. Discussion: The technique of using a moulding balloon to confirm accurate cannulation of the contralateral gate is a good method of eliminating doubt whilst maintaining a stable wire and catheter position.
