Iliac Artery Occlusion in a Patient With Allograft Renal Transplant Causing Refractory Heart Failure and Simulating Renal Artery Stenosis With Solitary Kidney

Abstract

Renal dysfunction after transplant is rare and associated iliac artery stenosis leading to refractory heart failure is extremely rare. Renal artery stenosis in a solitary kidney is known to lead to severe hypertension and acute pulmonary edema. Revascularization with percutaneous transluminal angioplasty of the solitary renal artery stenosis, or its equivalent, can resolve this syndrome and normalize blood pressure and volume status, though the event of hypertension is thought to occur within 15 days of transplant. We describe a case here of iliac artery stenosis with refractory acute heart failure, severe hypertension and threatened renal allograft transplant occurring 3 years after the transplant. Subsequent diagnosis and revascularization were curative. J Med Cases. 2019;10(1):14-17 doi: https://doi.org/10.14740/jmc3218
