Purpose: To report the use of a branched, balloon-deployable stent-graft to treat abdominal aortic aneurysm (AAA) in the setting of a solitary kidney.
Case report: A 72-year-old man with a solitary intrapelvic kidney and multiple comorbid conditions was diagnosed with an asymptomatic 5.3-cm abdominal aortic aneurysm (AAA); the renal artery emerged from the aneurysm sac. A customized branched, balloon-deployable, aortomonoiliac stent-graft was utilized to exclude the AAA and preserve perfusion to the single renal artery. A synthetic bypass was then implanted to restore perfusion to the contralateral limb. The diameter of the aneurysm decreased from 5.3 to 2.7 cm at 18 months. The renal artery was patent without evidence of stenosis; renal function was normal.
Conclusion: The deployment of a novel branched stent-graft represents an interesting alternative approach to the treatment of a juxtarenal aneurysm.
