The Role of Spatial Aortic Arch Architecture in Type B Aortic Dissection.

Objective: The incidence of type B aortic dissection (TBAD) is increasing worldwide; however, the underlying pathomechanisms are not conclusively understood. This study explores the geometric architecture of the aortic arch and supra-aortic branches in TBAD patients as opposed to non-TBAD patients.

Methods: Patient characteristics were retrieved from archived medical records.
