剖検心における冠動脈拡張術(CA)後の病理学的変化について

抄録

We observed the pathological findings induced by coronary angioplasty in human postmortem hearts.
The consequence followed as;
1) Intimal splitting was most frequent of all findings (26%).
2) The media and the intima of non atheromatous lesions were well stretched and atheromatous lesions with a hyalinized fibrous cap projected to the outside, but was not compressed. The mechanical destruction was found in lesions with severe stenosis by angiogram.
3) The mechanical destruction of intima began from 2 atm of balloon pressure and increased gradually at higher pressure.
