Repeated transluminal endovascular Inoue stent graft placement for progressive dilatation of prosthetic graft that had been repaired with Inoue stent graft placement for dilatation 23 years after extraanatomical bypass.

A 76-year-old man had undergone aneurysm exclusion and ascending abdominal aortic extraanatomical bypass for a thoracoabdominal aortic aneurysm in 1978. In 1983 hemoptysis occurred, and resection and closure of the central stump of the aorta and a left lower lobectomy were performed. Dilatation (phi50 mm) of a prosthetic graft (Cooley Graft phi18 mm) used for extraanatomical bypass was noted in 2001 and was repaired by placement of an Inoue stent graft. However, the aneurysm diameter increased further (phi70 mm), although no endoleak was noted: Placement of an Inoue stent graft covering the whole length of the prosthetic graft was repeated in 2006. The postoperative course was smooth, no endoleak occurred, and the patient was discharged 2 weeks after surgery.
