Background— Surgical interventions have been performed to ameliorate the complications of Takayasu’s arteritis. However, the efficacy of surgery to increase long-term survival has not been established.

Methods and Results— A retrospective review was performed on the survival of 106 consecutive patients with Takayasu’s arteritis who underwent surgical treatment during the past 40 years. Their ages ranged from 5 to 69 years (mean±SEM, 31.7±1.3 years). Survival was compared with the reported results of medically treated patients according to Ishikawa’s prognostic classification. There were 12 hospital deaths, and the remaining 94 patients were followed up from 8 months to 41.8 years (mean, 19.8 years). A serious long-term complication was anastomotic aneurysm, with a cumulative incidence at 20 years of 13.8%. Thirty-one late deaths were observed, and the major cause was congestive heart failure. The overall cumulative survival rate at 20 years was 73.5%. The prognostic classification by Ishikawa had little influence on the survival of surgically treated patients. For stage 3 patients, surgery seemed to increase survival; however, surgery-related complications conversely decreased the survival of stage 1 patients.

Conclusions— Surgery seems to increase the long-term survival of patients with stage 3 Takayasu’s arteritis, whereas conservative treatment is recommended for those with stage 1 or 2 disease. An anastomotic aneurysm may occur at any time after surgery, and regular follow-up using imaging modalities such as multi-detector CT, MRI, or ultrasonography at least once every several years for the rest of the patient’s life is mandatory for the early detection of anastomotic aneurysm.
