Hepatorenal bypass resulting in dialysis independence in case of acute renal failure

Abstract

In the present case report, we have described a patient with bilateral renal artery occlusion resulting in the acute onset of refractory hypertension and renal failure requiring hemodialysis. Endovascular stenting of the renal arteries was not feasible owing to extensive aortic and renal orifice calcification. After consultation with nephrology and medical optimization, the patient underwent unilateral hepatorenal bypass, with subsequent improvement in renal function and sustained freedom from dialysis. Although percutaneous revascularization has become the preferred option for surgical management of renal artery occlusion, the findings from the present case have demonstrated that hepatorenal bypass remains a viable alternative for more complex cases.
