右冠状动脉内支架(尸体X线)

右冠状动脉内支架(尸体X线)

尸体心脏X线检查显示:右冠状动脉内支架。患者死亡两年前曾行冠状动脉成形术。血管成形术能有效恢复局限性狭窄血管的血流。然而血管成形术原位的动脉粥样斑块结构可能改变,并有再次发生闭塞的可能。冠脉支架能够保持冠脉的开放状态并延迟再狭窄。冠脉支架的并发症很少见。

This postmortem radiograph of the heart reveals the presence of a stent in the right coronary artery following an angioplasty procedure performed two years prior to death. Angioplasty can be effective in restoring coronary blood flow by treating focal narrowing. However, there is a tendency for atheromatous plaques to remodel and for re-occlusion to occur at the site(s) of angioplasty. The stent helps to keep the coronary lumen open and delay restenosis. The rate of complications from stents is minimal.
