BACKGROUND: Spontaneous rupture risk of a renal artery aneurysm (RAA) is extremely low. Indications for surgical repair of RAA remain uncertain. OBJECTIVE: Long-term outcomes of conservative therapy and surgical repair were evaluated. PATIENTS: The study included 58 patients (17 males, 41 females) who were diagnosed with RAA during the last 21 years. Median age at the time of diagnosis was 62 (19-85) years, and the median follow-up 69 months (range 3-216). METHODS: The patients were divided into two groups, conservative group (n = 30) who had been followed with blood pressure control, and treatment group (n = 29), who underwent an intervention. RESULTS: Multiple efferent aneurysmal branches were observed in seven conservative and 16 treatment cases (P = .002). The median maximum diameter of the aneurysm was lower in the conservative than the treatment group (15 versus 25 mm, P = .005). Two conservative group cases showed increases in aneurysm size during follow-up. The hypertensive state showed essentially no change in either group during the follow-up. Renal function decreased with age similarly both in conservative and treatment groups. CONCLUSIONS: Our conservative management criteria for RAA are justifiable and even too strict.
