U Stent-Graft Technique as a Treatment for Homolateral Metachronous Common Iliac and Internal Iliac Arteries Aneurysms after Open Surgery

We report a case of a metachronous common iliac artery and the internal iliac artery (IIA) aneurysm developed 8 years after an aortobi-femoral bypass for treatment of abdominal aortic aneurysm associated at chronic occlusion of the right iliac axis. To exclude the metachronous aneurysm on the left iliac axis and to maintain the pelvic circulation, an external to IIA endografts were positioned ("U stent-graft technique"). At 6-month follow-up, the computed tomography scan showed patency of the endografts, of the bypass and of the IIA, without endoleak, or other adverse events.
