Retrograde Type A aortic dissection associated with thoracic endovascular aortic replacement appears fortunately uncommon occurring in approximately 2% of TEVAR cases. Most cases have been associated with TEVAR repairs of acute Type B aortic dissection but some have been reported with chronic dissection, aneurysm, and previous traumatic aortic injury. The etiology remains unclear, but direct trauma caused by the bare proximal stent frame may be a cause. Although mortality from both non-operative and operative repair of TEVAR-RTAAD remains high, it appears that patients who undergo urgent open surgical repair fair better. No cases of endovascular repair of TEVAR-RTAAD have been reported.
