Combined aortic and renal arterial reconstruction

Area of Science:

• Vascular Surgery
• Cardiovascular Surgery
• Surgical Outcomes

Background:

• Vascular surgeons commonly believe that combining renal arterial procedures with aortic replacement increases patient morbidity and mortality.
• This belief has historically influenced surgical decision-making regarding complex aortic and renal artery interventions.

Purpose of the Study:

• To evaluate the hypothesis that combined renal arterial and aortic reconstruction significantly increases morbidity and mortality.
• To assess the safety and outcomes of performing these procedures concurrently.

Main Methods:

• Retrospective review of 102 consecutive primary operations involving both renal arterial and aortic reconstruction.
• Analysis of patient demographics, surgical techniques (aortorenal bypass grafts, arterial reimplantations, endarterectomies), complications, and hospital mortality.
• Data collected from patients undergoing aortic replacement with knitted Dacron grafts.

Main Results:

• The study included 69 men and 33 women, with an average age of 63 years.
• A total of 128 renal arteries were revascularized.
• Thirty-five complications occurred in 24 patients, with four hospital deaths, suggesting a manageable risk profile.

Conclusions:

• Combining renal arterial and aortic reconstructions can be performed without a significant increase in patient risk.
• Optimal conditions and careful surgical planning are key to achieving favorable outcomes in combined procedures.
• The findings challenge the traditional view of increased risk associated with concurrent renal and aortic reconstruction.
