Drug-coated balloon versus uncoated balloon angioplasty for femoropopliteal artery ischemic disease:a meta-analysis of curative effect and safety / 介入放射学杂志

ABSTRACT

Objective To conduct a meta-analysis of the curative effect and safety of the drug-coated balloon (DCB) and uncoated balloon (UCB) in treating femoropopliteal artery ischemic disease in order to provide more credible conclusion to guide clinical practice.Methods By retrieving relevant documents contained in Medline,EMbase,Cochrane library,EBSCO,Springer Link,Scopus,Web and other data pools,the research articles of clinical trials that met the inclusion and exclusion criteria were collected.According to the risk assessment standard of Cochrane collaboration network,the academic qualities of included articles were evaluated,the relevant data were extracted,then,the meta-analysis was conducted with RevMan5.3 software.Results A total of 8 papers were collected,which were originated from 6 clinical trials (from 2008 to 2015) and included 1188 patients in total.DCB group had 722 patients,and UCB group had 466 patients.Meta analysis showed that the target lesion revascularization (TLR) rates at 6,12 and 24 months after angioplasty in DCB group were significantly lower than those in UCB group.The late lumen loss (LLL) amount and re-stenosis rate at 6 month after angioplasty in DCB group were lower than those in UCB group.No statistically significant differences in amputation rate and mortality at 6,12 and 24 months after angioplasty existed between the two groups.Conclusion In treating femoropopliteal artery ischemic disease,the use of DCB is superior to the use of UCB in aspects of TLR rate,LLL amount and re-stenosis rate,besides,no significant difference in safety exists between DCB and UCB.Therefore,priority should be given to the use of DCB when the patient's economic conditions permit.
