A Unique Body Floss Technique for Reduction of Sealing Loss on the Lesser-Curvature Side in Thoracic Endovascular Repair

It remains challenging to reduce sealing loss on the proximal lesser-curvature side in thoracic endovascular repair of blunt traumatic thoracic aortic injuries without covering the left subclavian artery. We describe a unique body floss technique for reducing sealing loss during proximal landing. In this technique, the conformable GORE TAG (W. L. Gore & Associates) can be positioned closer to the left subclavian artery and deployed more horizontally compared with the conventional procedure, which allows the device to fit better into the aortic wall. This technique is a promising strategy for treating blunt traumatic thoracic aortic injuries.
