Abstract    Stenting of lower extremity artery occlusive diseases has become a mainstream means. Because of the characteristics of the arterial lesions and biological stress, restenosis after stenting is an unavoidable problem,which usually need twice or even multiple interventions . The current strategies for restenosis are drug therapy, balloon dilatation, volume reduction technology, re-stent placement and drug-coated equipment and so on. A majority of scholars believe that balloon dilatation, volume reduction techniques and re-stent placement have some limitations. However,drug-coated devices, as new endovascular treatment means, have brought new hope.

Key words: lower extremities artery occlusion, in-stent restenosis, endovascular treatment

摘要：

下肢动脉狭窄及闭塞性病变采用支架置入已成为主流手段。由于下肢动脉独特的病变特点和生物学应力，支架置入后的再狭窄是不可回避的问题，往往需要进行二次甚至多次干预。目前对于再狭窄的治疗方法有药物治疗、球囊扩张、减容技术、再次支架置入及载药器材应用等。多数学者的研究认为球囊扩张、减容技术及再次支架置入有一定的局限性，载药器材作为新兴的腔内治疗手段，带来了新的希望。
