摘要
自从血管成形术应用于临床,血管再狭窄问题就随之而来,放射性核素血管内近距离治疗已产生富有希望的结果。现综述放射性核素近距离治疗的辐射机制、两种基本操作平台、放射性核素的选择、吸收剂量和剂量率、疗效、副作用和工作人员受照剂量等。
Dating from the inception of percutaneous angioplasty,restenosis has been the postprocedural Achilles heel.Intravascular brachytherapy using gamma or bata radionuclides has generated tremendous excitement with promising results.The review gives update on intravascular brachytherapy,including the mechanism of radiation preventing restenosis,two basic platform for delivering endovascular radiation,the option of radianuclides,dose and dose rate,therapeutic effects,side effects and personnel exposure.
