Renal artery revascularization using the inferior mesenteric artery as an inflow source with a long-term follow-up.

This case describes a 72-year-old woman with a history of chronic kidney disease stage III presented with bilateral renal artery stenosis with a progressively atrophied right kidney. At the time of surgery, the atrophied kidney was nonfunctional. Therefore, the patient underwent unilateral renal artery revascularization via the inferior mesenteric artery as an inflow. A 7-year follow-up revealed improvement in the kidney function and stabilization of blood pressure, which was controlled with less number of antihypertensive medications. In brief, open surgical correction of the renal artery stenosis using the inferior mesenteric artery as an inflow source can retrieve renal function in selected hypertensive patients with ischemic nephropathy.
