Risk factors analysis of stent fracture after superficial femoral artery and proximal popliteal artery stenting
Abstract：Objective To study the risk factors of stent fracture,and determine the relationship between stent fracture and in-stent restenosis after superficial femoral artery and proximal popliteal artery stenting.Methods From March 2013 to March 2016,96 consecutive patients (106 limbs) who underwent endovascular stenting therapy in superficial femoral artery and proximal popliteal artery were followed up by the methods of Doppler ultrasound scanning,X-ray scanning,computed tomographic angiography or digital subtraction angiography at Department of Vascular Surgery,Renji Hospital,School of Medicine,Shanghai Jiao Tong University.Statistical analysis was performed by using SPSS.Results Overall,stent fractures were detected in 38 of 106 treated legs (35.8％).TransAtlantic Inter-Society Consensus(TASC) Ⅱ classification (P ＜ 0.001),total stent length (P ＜ 0.001),and increased overlap zone (P=0.01)were statistically significant risk factors of stent fracture.The research also found that the highest incidence of fracture type was multi-struts fracture,and the highest incidence of the targeted arterial segment was the superficial femoral artery adductor canal segment.Conclusion TASC Ⅱ classification,total stent length and increased overlap zone were risk factors of stent fracture.
