Endovascular stent graft treatment for stenosis in isolated infrarenal abdominal aortic dissection: A case report

We report a case of complicated isolated infrarenal abdominal aortic dissection (IAAD) that was treated with stent graft. A 79-year-old man presented with acute bilateral lower limb pain. A contrast-enhanced CT performed 2 h later revealed sever stenosis of infrarenal abdominal aorta due to IAAD. Angiography identified a primary tear just below the upper end of the IAAD. A smaller stent graft was placed distally to avoid stent graft-induced new entry, and a large stent graft was placed proximally to cover the primary entry. The stenosis improved immediately after the procedure, and pain relief was achieved. Stent graft placement for entry closure appeared to be an effective for IAAD.
