Surgery and Endovascular Management in Patients With Takayasu's Arteritis: A Ten-Year Retrospective Study

Abstract

Takayasu's arteritis (TA) is an uncommon chronic vasculitis, and there is a lack of long-term large cohort studies regarding the optimal revascularization outcomes of patients with TA. One hundred and sixteen patients with TA who underwent surgery or endovascular repair over a 10-year period were studied retrospectively. One hundred and fifty-four vascular procedures were performed consisting of 69 open and 85 endovascular repairs. After a mean follow-up period of 48.5±38.5months, three cases each of cerebrovascular accident (CVA) and death occurred in the open repair group while two cases of CVA and 4 deaths were observed in the endovascular repair group. At 1, 3, 5, and 10years of follow-up, the primary patency rates were 97.3%, 86.2%, 70.5%, and 48.8% in the open repair group and 93.3%, 73.1%, 57.5%, and 31.8% in the endovascular repair group, respectively. The primary assisted patency rates were 98.2%, 90.3%, 73.2%, and 47.2% in the open repair group and 95%, 81%, 64.4%, and 35% in the endovascular repair group, respectively. The secondary patency rates were 98.2%, 96.1%, 83.5%, and 56.2% in the open repair group and 98.7%, 86%, 71.2%, and 44.9% in the endovascular repair group, respectively. The cumulative survival rates were 96.9%, 96.9%, 96.9%, and 90% in the open repair group and 97.4%, 97.4%, 88%, and 79.2% in the endovascular repair group, respectively. Both surgical repair and endovascular management are safe and efficient modes of treatment of TA. Surgical repair showed long-term durability, and it is suitable for complex lesions and failed cases of endovascular management.
