Mid-Term Outcomes of Stent Overlap in Long Total Occluded Lesions of Superficial Femoral Artery

BACKGROUND: Superficial femoral artery chronic total occlusion (SCTO) is a common type of peripheral arterial disease (PAD). Endovascular therapy is a treatment approach that has a poor long-term success rate in this group. The aim of this study was to compare the mid-term results of two different u...

description BACKGROUND: Superficial femoral artery chronic total occlusion (SCTO) is a common type of peripheral arterial disease (PAD). Endovascular therapy is a treatment approach that has a poor long-term success rate in this group. The aim of this study was to compare the mid-term results of two different uses of nitinol stents in long SCTO lesions (>100 mm): the use of one long stent or two shorter stents. MATERIAL/METHODS: Of 154 patients who underwent percutaneous infrainguinal interventions from 2011 to 2014, a total of 170 CTO lesions were selected for this retrospective study analysis. The mean age of the study population was 63.4±10.4 years (range 29–89 years); 71.8% of the patients were male. RESULTS: Patients were divided into two groups according to the number of stents used. Patients treated with a single stent were placed into group A and patients treated with two stents were placed into group B. The stent fracture rate was significantly higher in group B compared to group A (29.2% vs. 42%). Type 1 and 2 fracture rates were higher in group A, but type 3 and 5 fracture rates were significantly higher in group B. The rate of stent restenosis was significantly higher in group B compared to group A (45.1% vs. 54.5%, p=0.05). CONCLUSIONS: Mid-term patency rate was low in patients with long totally occluded superficial femoral artery (SFA) lesions. Using a long single stent had an acceptable mid-term patency rate compared to using a two stent strategy. Stent fracture seemed to be the main reason for in-stent restenosis in cases of multiple stenting. A long single stent strategy may be more appropriate and reasonable than a two stent strategy in the treatment of long SFA lesions.
