Dual true and false lumen stent graft technique for endovascular repair of isolated common iliac artery aneurysm in chronic type A10 dissection.

A 52-year-old man presented with a chronic type A10 aortic dissection with subsequent aneurysmal degeneration of the left common iliac artery measuring up to 4.6 cm. He had previously undergone hemiarch replacement, which was complicated by renal failure. Owing to the presence of the growing aneurysm, he was unable to be listed for renal transplantation. He declined open operative repair. A novel dual true and false lumen stent graft technique using thoracic endografts was performed to successfully exclude the aneurysm. Follow-up imaging demonstrated aneurysm sac regression, with the patient subsequently undergoing renal transplantation.
