The Impact of Intimal Tear Location and Partial False Lumen Thrombosis in Acute Type B Aortic Dissection

In a biologic model of ATBAD, the number, location, and FL thrombosis status determine FL pressure. In the setting of partial FL thrombosis, the FL pressure is reduced with proximal tear occlusion and increased with distal tear occlusion. Reduced FL pressure is related to retrograde flow.
