Extended aortic bypass for atherosclerotic occlusive disease of high abdominal aorta

Area of Science:

• Vascular Surgery
• Nephrology
• Cardiovascular Disease

Background:

• Atherosclerotic occlusive disease can affect major arteries, including the aorta.
• Extension of aortic atherosclerosis can compromise renal artery perfusion, leading to acute renal failure.
• Limb ischemia is a common complication of severe aortoiliac occlusive disease.

Observation:

• A 68-year-old male presented with acute renal failure secondary to atherosclerotic occlusion extending to the suprarenal aorta.
• The patient underwent complex bypass grafting surgery.
• Grafts included aorta-to-femoral bypass and additional saphenous vein grafts to renal and splenic arteries.

Findings:

• Successful bypass grafting restored blood flow to the lower extremities, alleviating limb ischemia.
• Renal artery revascularization via bypass grafting resolved the acute renal failure.
• The patient was able to discontinue dialysis following the intervention.

Implications:

• Surgical revascularization is a viable treatment for acute renal failure caused by aortic atherosclerosis.
• Complex aortic and visceral artery bypass grafting can effectively manage combined renal and limb ischemia.
• This case highlights the importance of considering aortic pathology in patients with unexplained renal failure and limb ischemia.
