Aneurysm Repair

Endovascular aneurysm repair (EVAR), despite its advantages over abdominal aortic aneurysm (AAA) open surgery, still presents risks of failure linked to Endograft (EG) migration. We here explore the link between intravascular blood flow features and Displacement Forces (DFs) acting on the EG. DFs are inversely associated with the amount of helical flow within the EG.

Aneurysm Repair

The most common technical concern in Endovascular Aneurysm Repair (EVAR) is the proximal landing zone of stent. Sandwich technique is the effective procedure to preserve internal iliac blood flow. This case report describes using this procedure for successful EVAR in patient with juxtarenal abdominal aortic aneurysm.
