Changing patterns in surgery for chronic renal artery occlusive diseases

Area of Science:

• Vascular Surgery
• Nephrology
• Cardiovascular Disease

Background:

• Chronic renal artery occlusive diseases pose significant risks to kidney function.
• Atherosclerosis is a leading cause of renal artery stenosis, particularly in older populations.
• Surgical management has evolved due to advances in hypertension treatment and endovascular techniques.

Purpose of the Study:

• To analyze surgical outcomes for chronic renal artery occlusive diseases.
• To identify the primary indications and etiologies for surgical intervention.
• To evaluate the effectiveness of various reconstruction techniques in salvaging renal function.

Main Methods:

• Retrospective review of 66 patients (69 operations) between 1985 and 1990.
• Analysis of patient demographics, etiology of disease, surgical procedures, and outcomes.
• Categorization of reconstruction methods based on donor arteries (aorta, aortic graft, other abdominal arteries).

Main Results:

• Atherosclerosis accounted for 90% of cases, with generalized disease in 83%.
• Renal function salvage was the primary goal in 72% of operations.
• 86% of patients undergoing renal salvage avoided long-term dialysis; operative mortality was 3%.

Conclusions:

• Modern surgical management of renal artery occlusive disease addresses advanced atherosclerosis and prioritizes renal function preservation.
• Complex reconstructions, often avoiding the aorta, are necessary due to disease severity.
• Improved medical management has shifted surgical indications from hypertension control to renal salvage.
