Abstract:
Objective To investigate the correlation between femoral popliteal artery stent fracture and in-stent restenosis (ISR) in patients with arteriosclerosis obliterans of superficial femoral artery and proximal popliteal artery after receiving stent implantation.Methods The clinical data of a total of 97 consecutive patients with arteriosclerosis obliterans of superficial femoral artery and proximal popliteal artery (107 diseased limbs in total),who were treated with primary stent implantation during the period from March 2012 to March 2016,were retrospectively analyzed.The imaging materials,including Doppler ultrasonography,plain radiography,contrast-enhanced CT scan,DSA,etc.were collected,and Kaplan-Meier survival analysis and other statistical analysis methods were used to analyze the related data.Results During the follow-up period,71 patients (72 limbs in total) developed ISR and the incidence of ISR was 67.3％ (72/107).The incidences of ISR in the stent-fracture group and non-fracture group were 84.2％ (32/38) and 58.0％ (40/69) respectively,the difference between the two groups was statistically significant (P=0.01).Conclusion After stent implantation of femoral popliteal artery,fracture of stent is one of the important risk factors for the occurrence of ISR.
