BACKGROUND: The clinical impact of stent fractures is still controversial. This study analyzed the incidence and the clinical impact of stent fractures after stenting of long femoropopliteal lesions.
METHODS: From November 2008 to October 2009, 58 patients (62 limbs) were treated in a single center with a primary nitinol self-expanding stent for Trans-Atlantic Inter-Consensus (TASC) C and D de novo femoropopliteal lesions. Patients were prospectively followed by medical and duplex scan examinations. Stent fractures were assessed by biplane X-rays at 12 months. Logistic regression analysis was performed.
RESULTS: At 1 year a complete follow-up was obtained in 42 limbs/90 stents. The median length of the stented segment was 240 ± 180 cm with a mean of 2.1 (1-4) stents per patient. Sixteen stents (17.8%) were fractured: one type I (asymptomatic); seven type II (2 restenosis); five type III (asymptomatic), and three type IV stent fractures (1 restenosis). Stent diameter (p = .04) and stent implantation in the distal part of the superficial femoral artery (p = .05) were positively associated with stent fractures. Stent fracture had no influence on restenosis.
CONCLUSION: This study suggests that the high stent fracture rate associated with endovascular treatment of long femoropopliteal lesions should be balanced with its low clinical impact.
