Mid-term outcomes of different treatments of internal iliac artery in endovascular aneurysm repair.

Objective: To evaluate the mid-term outcomes of different treatment strategies for the internal iliac artery (IIA) during EVAR.

Methods: This was a retrospective study. All patients undergoing EVAR, who required treatment of at least one side of IIA from January 2013 to July 2022 in a single center, were included.

Hyperhomocysteinemia may aggravate abdominal aortic aneurysm formation by up-regulating RASSF2.

Abdominal aortic aneurysm (AAA) is a fatal cardiovascular disorder with high mortality and morbidity rates. To date, no drug has shown to significantly alleviate the risk of AAA. Previous studies have indicated that hyperhomocysteinemia (HHcy) significantly increases the incidence of AAA by disrupting endothelial cell homeostasis; however, the potential molecular mechanisms require clarification.

Construction of a canine model with acute type B aortic dissection using a self-made pressure-driven flow device.

A reproducible canine aortic dissection (AD) model would be useful for evaluating the performance of novel endovascular treatment devices. Therefore, we attempted to create a reproducible canine model of Stanford type B AD (TBAB) by a surgical method. Computed tomography angiography was performed 2 h after the procedure to determine if a false lumen was present, and follow-up imaging was performed 10 d after the procedure using digital subtraction angiography, intravascular ultrasound (IVUS), and color Doppler flow imaging (CDFI) to confirm stable persistence of the false lumen.
