Type B aortic dissection (TBAD) represents a serious medical emergency with up to a 50% associated 5-year mortality caused by thoracic aorta, dissection-associated aneurysmal (DAA) degeneration, and rupture. Unfortunately, conventional size-related diagnostic methods cannot distinguish high-risk DAAs that benefit from surgical intervention from stable DAAs. Our goal is to use DAA stiffness measured with magnetic resonance elastography (MRE) as a biomarker to distinguish high-risk DAAs from stable DAAs.

- This study explores how the degree of graft oversizing in endovascular aneurysm repair (EVAR) affects the strain in the seal zone of abdominal aortic aneurysms, suggesting that excessive strain reduction may negatively impact the aneurysm neck.
- The researchers conducted experiments using different types of endografts and assessed strain changes with ultrasound elastography, comparing three oversizing levels: 20%, 30%, and 50%.
- Results indicated significant differences in strain reduction when comparing normal (empty) phantoms to those with oversizing, highlighting the potential risks associated with high graft oversizing.
