Endovascular repair of abdominal aortic aneurysm associated with residual type B aortic dissection utilizing iliac branch endoprosthesis: a case report

This case report describes a unique instance of using endovascular aortic repair (EVAR) with an iliac branch endoprosthesis (IBE) to treat an abdominal aortic aneurysm and a common iliac artery aneurysm. These aneurysms were associated with residual type B aortic dissection following a previous thoracoabdominal aortic replacement. The patient had a history of aortic dissection and aneurysms. Due to the complexity of his condition, involving both thoracoabdominal and iliac artery issues, a two-stage surgical strategy was initially planned. EVAR with IBE was chosen to preserve blood flow to the right internal iliac artery, which was crucial for preventing spinal cord ischemia. The procedure was successful, with no complications and aneurysm shrinkage observed after one year.

• 1
  EVAR with IBE can be safely performed for abdominal aortic and common iliac artery aneurysms associated with residual aortic dissection after thoracoabdominal aortic graft replacement.
• 2
  Embolizing the branch to the false lumen and using IBE are key to the success of this approach in patients with residual aortic dissection.
• 3
  Follow-up CT scans showed no enlargement of the aneurysms one year postoperatively, indicating a positive outcome.
