This demonstrates a comparison of the average maximal thoracic aortic diameter change after thoracic endovascular aortic aneurysm repair (TEVAR) for chronic type B aortic dissection (cTBAD) with aneurysm formation as a function of residual false lumen (FL) patency. Patients with isolated infrarenal FL patency vs visceral aortic segmental patency vs distal descending thoracic aortic FL patency are compared. A significant difference (P < .0005) in diameter outcome is noted and primarily impacted by persistent perfusion of the FL in the distal descending thoracic aorta resulting in progression of aneurysm size.
