BACKGROUND
Optimal medical therapy after endovascular therapy in patients with critical limb ischemia (CLI) remains unclear. Therefore, we investigated whether cilostazol reduce restenosis after balloon angioplasty for infrapopliteal lesions in CLI patients.
METHODS
This study was performed as a multicenter, prospective, randomized, open-label, blinded-end point study with independent angiographic core laboratory adjudication. Sixty patients were eligible and 53 patients were enrolled and allocated. The primary end point was 3-month angiographic restenosis. The main secondary end points included major adverse limb event (MALE defined as requirement of any reintervention or major amputation), perioperative complications, major amputation, all-cause death, and hemorrhagic events.
RESULTS
A total of 53 patients were randomized and all received their allocated intervention. Two patients in the cilostazol plus aspirin group and 1 in the aspirin group did not undergo any angioplasty for infrapopliteal stenotic lesions, and therefore were excluded from analysis. Finally, 38 vessels in 25 patients in the cilostazol plus aspirin group and as many cases in the aspirin group were included in the analysis. There were no significant differences in baseline characteristics between the 2 groups. The 3-month restenosis rate was 82% in the cilostazol + aspirin group and 81% in the aspirin group, with no significant difference (P = 0.91). The MALE rate was 11% in the cilostazol plus aspirin group and 8% in the aspirin group (P = 0.73). In addition, no significant difference was observed in any secondary points.
CONCLUSIONS
Cilostazol did not reduce 3-month angiographic restenosis after balloon angioplasty for below-the-knee lesion in CLI patients.
