Evaluation of flow dynamics in distal stent graft-induced new entry using 4D flow MRI

Abstract

Distal stent graft-induced new entry may occur after stent grafting for aortic dissection. Four-dimensional magnetic resonance imaging is useful for predicting outcomes, showing accelerated flow and increased wall shear stress, indicating further false lumen expansion.

Keywords: 4D flow MRI; aortic dissection; dSINE; stent graft insertion.
