In the endovascular therapy, the vessel run off for the limb salvage is unclear. The purpose of this study was to survey whether the existence of the below–the–ankle (BA) artery run off affects major adverse limb event (MALE) with CLI patients after isolated below– the–knee (BK) interventions.
A multicenter retrospective analysis of infra–popliteal intervention done for CLI between March 2004 and October 2010, 798 limbs from 716 patients with tissue loss CLI (Rutherford 5,6) due to isolated BK lesions were studied. They were divided for two groups. One was BK lesions with BA (1 or 2 vessel run off) group, and the other was BK lesions without BA (0 vessel run off) group. Freedom from MALE, defined as major amputation or any revascularization, moreover, survival rate were also assessed.
Mean follow–up period was 19.0±17.7 months. Freedom from MALE was significantly different (60.9%, 38.2%, 25.8% at 1, 3, 5 years in the BK with BA group, and 48.4%, 28.2%, 20.5% in the BK without BA group, p=0.008, respectively). Moreover, survival rate was significantly different (79.9%, 61.4%, 48.8%, and 68.2%, 43.5%, 33.7% at 1, 3, 5 years, p< 0.001, respectively). By multivariate analysis, BA vessel run off was a significant predictor for MALE (hazard ratio, 0.72; 95% confidential interval, 0.57–0.92; p=0.009).
The existence of the BA artery run off was an important predictor for MALE of tissue loss CLI patients with isolated BK lesions.
