Modification of a Bifurcated Stent Graft for Aortouniiliac Endovascular Aneurysm Repair in a Renal Transplant Patient

Abstract

Introduction. We describe a case of aortouniiliac (AUI) endovascular aortic aneurysm repair (EVAR) using combined iliac limb and bifurcated body stent graft modular system. Case report. This technique is demonstrated in a 58-year-old man with a 6-cm abdominal aortic aneurysm suitable for EVAR. The patient has a functioning cadaveric renal transplant anastamosed to the mid right external iliac artery, an occluded left iliac system and stenosed right iliac system. The renal allograft was protected with minimal passage across the transplant artery origin using this modified approach. The patient was successfully treated with a bifurcated main body deployed within a contralateral limb endoprosthesis. Subsequent scans confirmed no endoleaks or stent migration. Conclusions. The AUI conversion from existing Gore excluder stent graft system is safe and should be considered when faced with challenging anatomy of a pelvic renal transplant, slender access, and contralateral iliac occlusion.
