支架内再狭窄(图)和支架术后再狭窄(图)

支架置入术是目前治疗冠心病的最主要的治疗方法,虽然药物支架的出现明显降低了支架再狭窄的发生率,但是并没有消除支架再狭窄。因此,随着支架置入患者数的增加,再狭窄患者也逐渐增多。然而再狭窄病变如果再次放支架,由于金属套金属再狭窄几率高很多。近年来,出现的药物球囊是治疗再狭窄病变的一种选择,药物球囊的意思是球囊表面带防止再狭窄的药物,在再狭窄病变充分扩张后应用药物球囊将药物释放到病变部位,再将球囊退

Circulation:股浅动脉支架内再狭窄,使用药物涂层气囊血管成形术效果更佳

关于股浅动脉(SFA)疾病的再狭窄预防,药物涂层气囊血管成形术(DCBA)被证明是优于标准气囊血管成形术(POBA)的。对于支架内再狭窄(ISR),DCBA由于POBA的证据仍然不明朗。研究人员在德国5个临床中心超过34个月的时间招募了119例SFA ISR和慢性下肢缺血患者,这些患者被前瞻性的随机分配接受DCBA(n=62)或POBA(n=57)。平均病变长度为82.2±68.4毫米。34个(2
