Objective: The aim of this study was to assess the strategy and surgical procedures for treating a renal artery aneurysm (RAA).
Patients and methods: We retrospectively reviewed the surgical strategy for 21 cases with RAA between 2001 and 2010 at this institution. Treatment was indicated for patients with an RAA larger than 2 cm and/or symptoms. Surgical treatment was the initial strategy, and coil embolization was indicated in the case of narrow-necked, saccular, extraparenchymal aneurysms.
Results: Fifteen patients in 21 cases received an aneurysmectomy and renal artery reconstruction with an in-situ repair. One patient underwent an unplanned nephrectomy, and coil embolization was performed in 5 patients.
Conclusion: In-situ repair was safe and minimally invasive. RAA, even in the second bifurcation, could be exposed by a subcostal incision, and the transperitoneal approach permitted the safe treatment of an RAA with acceptable results, in our simple preservation of renal function.
