Background/objective

Endovascular interventions for femoropopliteal (FP) arterial diseases are limited by the development of restenosis. Current drug coated devices are capable of preventing restenosis by releasing antiproliferative agents to the vessel wall. However, default strategies for the treatment of FP diseases remain controversial. The aim of this study was to investigate the efficacy differences between drug eluting stents (DES), covered stents (CS), and other commonly used endovascular treatments in FP lesions, including drug coated balloons (DCBs), bare metal stents (BMS), and percutaneous transluminal angioplasty (PTA).

Methods

A comprehensive network meta-analysis was conducted using data from relevant randomised control trials published up to 16 December 2018. Primary patency and target lesion revascularisation (TLR) at 12 months were set as the primary and secondary end points, respectively.

Results

Twenty-eight eligible trials including 4728 patients were selected. DES was ranked as the most effective treatment in the multidimensional analysis of primary patency; however, there was no significant difference in the efficacy of DES and that of CS, DCB, and BMS. However, in short lesions (<10 cm), DES was significantly more effective than DCB (odds ratio 0.35; 95% confidence interval 0.15–0.83). Primary patency at 12 months was significantly lower with PTA. In terms of preventing TLR, DCB was ranked first, followed by DES, CS, BMS, and PTA. TLR was significantly higher with PTA than with other treatment strategies.

Conclusion

The findings of this network meta-analysis suggest that this is not the appropriate time to identify the best endovascular treatment strategy for the FP segment. DES is effective in maintaining mid-term patency, especially in short lesions, whereas DCB seems more suitable for clinical use.
