摘要:
临床上β源放射性支架出现边端再狭窄,即所谓的"糖果纸"样现象。其产生的机制可能为支架边端放射性活度降低,支架边缘组织损伤过大及支架边缘低剂量辐射刺激组织增生。解决边端再狭窄的对策为应用热、冷端支架及γ支架,增加支架端侧的放射性强度,使用钝边球囊安放支架等。
Abstract:
There is an "edge effect" or "candy wrapper" problem at the stent edges for β-particle emitting stent im-plantation. The mechanism for "candy wrapper" may conclude low activity level of radiation, aggressive injury to vessel at the margins of the stent and neointimal proliferation due to low-dose radiation stimulation. The methods to solve the "candy wraper" could be proposed:(1) the square-shouldered balloon, (2) the cold-end stent, (3) the hot-end stent, (4) a self-expanding radioactive stent, (5) theγ-stent and so on.
