Background/Purpose: Data regarding long term outcome of patients with thromboangiitis obliterans (TAO) are lacking and most series come from India and Japan. We assess long-term outcome and prognostic factors in a large cohort of TAO.
Methods: Retrospective multicenter study of characteristics and outcomes of 224 TAO patients fulfilling Papa’s and/or 5 Shinoya’s criterias were analyzed. Factors associated with vascular events and amputations were identified.
Results: The median age at diagnosis was 38.5 [32-46] years, 51 (23.8 %) patients were female and 81.7% were Caucasians. After a mean follow up of 5.7 years, vascular events were observed in 58.9%, amputations in 21.4% and death in 1.4%. The 5-, 10- and 15-year vascular event free survival and amputation free survival were 41% and 85%, 23% and 74% and 19% and 66%, respectively. Ethnic group (non-Caucasian) (HR 2.35 [1.30-4.27] p=0.005) and limb infection at diagnosis (3.29 [1.02-10.6] p=0.045) were independent factors of vascular events. Factor associated with amputation was limb infection (HR=12.1[3.5-42.1], p<0.001). Patient who stopped their tobacco consumption had lower risk of amputation (p=0.001) than those who continued.
Conclusion: This nationwide study shows that 34% of TAO patients will experience an amputation within 15 years from diagnosis. We identified specific characteristics that identified those at highest risk for subsequent vascular complications and amputations.
