Background Retrograde dissection (RD) can be a serious complication after thoracic endovascular aortic repair (TEVAR), with retrograde type A dissection (RTAD) particularly life-threatening. Prior studies have suggested that treatment timing, anatomic characteristics, device selection, and procedural conduct of TEVAR performed for type B aortic dissection could mitigate the occurrence of RD. The Vascular Quality Initiative TEVAR for Dissection Registry is an ongoing project meant to satisfy Food and Drug Administration requirements for postmarket approval surveillance of the Gore conformable TAG thoracic endoprosthesis (W.L.
