Flow dynamics, false lumens and implications for endografting

The complications of endovascular stenting for type B aortic dissections are well-described and include paralysis from spinal cord ischemia, retrograde dissection, stroke, and access site complications. Owing to the inherent risk associated with this procedure, current practice is to withhold endovascular therapy unless the risk-benefit balance is in favor of intervention, such as with acute malperfusion or aneurysmal degeneration. Emphasis is placed on coverage of the entry tear, which has been advocated theoretically as the primary method to restore normal aortic hemodynamics and induce false lumen thrombosis, despite notable paucity of direct flow modeling to support this claim.
