Transseptal Guidewire Stabilization to Facilitate Endograft Delivery During Thoracic Endovascular Aortic Repair of a Giant Tortuous Thoracic Aortic Aneurysm.

ABSTRACT:

Objective

To describe transseptal guidewire stabilization to facilitate endograft delivery into the aortic arch during thoracic endovascular aortic repair (TEVAR) when aortic tortuosity impedes delivery system advancement.

Key steps

The key steps to the procedure are as follows: the physician modifies the arch endograft, the patient is given general anesthesia, ultrasonography-guided percutaneous access is obtained, septal puncture is performed, a Mullins-type sheath is advanced into the ascending aorta over the balloon-tipped catheter, a coaxial hydrophilic guidewire is exteriorized from the right femoral artery, a transseptal snare traps the Lunderquist guidewire entering the transseptal sheath from the aorta, traction is applied, the endograft delivery system is advanced
