Gore cTAG sleeve-associated maldeployment for traumatic aortic injury with aberrant right subclavian artery

Abstract

A 30-year-old woman presented following a motor vehicle collision with a grade III blunt thoracic aortic injury and an aberrant right subclavian artery. Using intraoperative ultrasound and diagnostic subtraction angiography, we deployed an aortic endograft (cTAG; W.L. Gore & Associates), excluding the injury and aberrant right subclavian artery. The patient immediately lost arterial waveforms in her left arm, confirming incidental coverage of the left subclavian artery, likely due to the polytetrafluoroethylene sheath of the endograft. Her pulses returned after placement of a left subclavian chimney via retrograde brachial artery access.
