Background

With the recent improvement of device and endovascular treatment (EVT) technique, the success rate of chronic total occlusion (CTO) in ilio-femoral artery is very high; however, there are limited data regarding the impact of Stent implantation on the clinical outcomes as compared with balloon angioplasty alone.

Methods

A total 187 consecutive critical limb ischemia (CLI) patients (pts) underwent PTA. Among these pts, a total 121 (64.7%) CLI pts presented with ilio-femoral artery lesion (156 limbs, 189 lesions) and 75 pts were treated with Stents (100 Limb, 107 lesions). Provisional stenting was done once the balloon angioplasty result is not optimal. Periprocedural complications and clinical outcomes up to 12 months were compared between the two groups.

Results

At baseline, Balloon group had more diabetes, wound and infrapopliteal lesions whereas Stent group had more cerebrovascular accident and CTO lesions. Overall procedural success rate was 98.3% with similar rates of periprocedural complications. Major clinical outcomes including mortality, repeat revascularization and surgical intervention were similar between the two groups (Table). After the adjustment, the major clinical outcomes were similar between the two groups.

Conclusion

Once the significant ilio-femoral lesions were successfully treated either by balloon angioplasty alone or provisional stenting, major mid-term angiographic and clinical outcomes were similar between two treatment modality.
