Feasibility of measuring magnetic resonance elastography-derived stiffness in human thoracic aorta and aortic dissection phantoms.

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.

Endovascular vs open repair of ruptured abdominal aortic aneurysms with hostile neck anatomy.

Objective: Aneurysm neck anatomy in ruptured abdominal aortic aneurysms (rAAAs) is often complex, limiting the feasibility of endovascular repair (EVAR). The objective of this study was to compare the outcomes of EVAR and open surgical repair (OSR) for treatment of rAAAs in patients with hostile neck anatomy (HNA). The secondary aim was to review the clinical characteristics and anatomic risk factors predictive of mortality.

TREO Aortic Endograft Demonstrates Superior Aneurysmal Sac Regression Over Mid-Term Follow-Up.

Introduction: Aneurysmal sac regression is a predictor of long-term outcomes after endovascular aneurysm repair (EVAR). This study aimed to compare a large cohort of TREO and non-TREO endografts over a mid-term follow-up and compare abdominal aortic aneurysm sac regression. The hypothesis was that TREO endografts have an increased sac regression by 24 mo.
