Renal Artery Revascularization Using the Inferior Mesenteric Artery as an Inflow Source with a Long-Term Follow-Up

Abstract This case describes a 72-year-old female with a history of chronic kidney disease stage III presented with bilateral renal artery stenosis (RAS) with a progressively atrophied right kidney. At the time of surgery, the atrophied kidney was non-functional. Therefore, the patient underwent unilateral renal artery revascularization via the inferior mesenteric artery (IMA) as an inflow. A seven-year follow-up revealed improving kidney function and stabilizing of blood pressure that controlled with less number of antihypertensive medications. In brief, open surgical correction of the RAS using IMA as an inflow source can retrieve renal function in selected hypertensive patients with ischemic nephropathy.
