The Kaplan–Meier curves of the primary patency (left) and assisted primary patency (right) for different interventions for central venous lesions. PTA is depicted with solid lines, PTS with bare stent with short segments, and PTS with stent graft with the dotted line. PTS with bare metal stent had a lower primary patency among 3 to 24 months compared with PTS with stent graft (p = 0.011), and a lower primary patency after 13 months compared with PTS with stent graft (landmark analysis, p = 0.033).
