Yammine H, et al. - Clinical, anatomic, and procedural characteristics of patients who developed retrograde type A dissection (RTAD) after thoracic endovascular aortic repair (TEVAR) for type B aortic dissection (TBAD) were evaluated via analyzing 186 patients who underwent TEVAR for TBAD at a multidisciplinary aortic center. None of the easily identifiable demographic features was noted to be correlated with the development of RTAD after TEVAR for TBAD. However, its development was identified in correlation with proximal landing zones in zone 1 and 2 and an ascending diameter >4 cm. Furthermore, patients with RTAD exhibited the presence of partial or complete false lumen thrombosis, as well as more complicated presentation with renal ischemia, significantly more frequently. Long-term surveillance is recommended for TBAD patients, as type A dissections in the patients occurred even after 1 year.
