Rapidly Expanding Renal Artery Aneurysm Open Repair: A Case Report

Area of Science:

• Vascular Surgery
• Nephrology
• Radiology

Background:

• Renal artery aneurysms (RAAs) are uncommon vascular lesions, accounting for less than 1% of all aneurysms.
• The natural history and optimal management strategies for RAAs remain incompletely understood.
• RAAs can pose significant risks, including rupture and renovascular hypertension.

Observation:

• A 58-year-old female presented with bilateral renal artery aneurysms.
• The right renal artery aneurysm demonstrated rapid growth over a 1-year follow-up period.
• The patient's age and complex aneurysm anatomy precluded endovascular repair options.

Findings:

• Open surgical repair was successfully performed for the right renal artery aneurysm.
• The procedure involved resection of the aneurysm and primary anastomosis of the renal artery.
• This case demonstrates the feasibility of open surgical management for complex RAAs.

Implications:

• Open surgical repair remains a viable option for managing complex renal artery aneurysms when endovascular approaches are not feasible.
• This case contributes to the limited literature on the surgical management of RAAs.
• Further research into the natural history and comparative effectiveness of different RAA treatment modalities is warranted.
