Key result
An off-label iliac extension stent graft successfully treated an asymptomatic infrarenal aortic dissection and secured a safe pathway for a subsequent TAVI procedure without complications.
Why the study?
Isolated abdominal aortic dissection is rare with little evidence on optimal treatment, and standard stent graft systems are challenging in narrowed distal aortic segments without aneurysm.
Case Report (n=1)
Off-label use of an iliac stent graft extension can facilitate endovascular access for TAVI in patients with severe infrarenal aortic dissection and atherosclerosis.

Daskalov et al. (2025) conducted a case report in Asymptomatic infrarenal aortic dissection (n=1). Off-label iliac extension stent graft was evaluated on Procedural success and complication rate. An off-label iliac extension stent graft successfully treated an asymptomatic infrarenal aortic dissection and secured a safe pathway for a subsequent TAVI procedure without complications.
