Abstract

A 77-year-old man with a history of stent implantation in the right common iliac artery（CIA） and the left external iliac artery（EIA） was admitted to our hospital for a rapid growth of an aneurysm（ max 53 mm） at Th11 level of the descending aorta. Although thoracic endovascular aortic repair （TEVAR） was required, there were many problems about access rout. The infrarenal abdominal aorta and the left EIA were severely calcified, and the lumens of the right CIA stent（5.3 mm） and the left EIA stent（ 4.3 mm） were small in size. Besides, the left CIA was short（13 mm）. Therefore, TEVAR was performed by retrograde approach from the left internal iliac artery（ IIA） with a tube graft conduit in the hybrid operation room. IIA is a useful option for an access rout in endovascular aortic repair.
