Impact of chronic outward force on arterial responses of proximal and distal of long superficial femoral artery stent

Abstract: Background Self-expanding nitinol stent (SENS) implantation is commonly oversized in the superficial femoral artery (SFA), and leads to chronic outward force (COF) and in-stent restenosis (ISR). This study aimed to investigate the impact of COF of oversizing SENS on ISR of SFA. Methods In patients with implanted SENS in SFA, intimal hyperplasia especially between proximal segment and distal segment was evaluated by quantitative angiography, and th… Show more

“…In the study group, the stentto-artery diameter ratio was significantly higher in the distal stent than in the proximal stent (1.55 ± 0.25 vs. 1.3 ± 0.2, p = 0.001). Similarly, the risk of ISR was significantly higher in the distal stent than in the proximal stent (52.6% vs. 37.3%, p = 0.029) [164].…”
