先天性心脏病法乐氏四联症的心肌细胞病理学(附2例报告)

ASSESSMENT OF MYOCARDIAL BIOPSIES TAKEN FROM TETRALOGY OF FALLOT WITH REPORT OF TWO CASES

2例先天性心脏病法乐氏四联症根治术中缺血期与再灌注期心肌组织显微及超微结构对比观察,发现再灌注期心肌结构损伤较缺血期并无加重,考虑可能与法乐氏四联症患儿(1)心内畸形的纠正;(2)内生性氧自由基清除剂含量高;(3)肺内白细胞聚集减少有关.

A comparative observation was made with microscopy and ultramicroscopy on myocardial biopsies taken from two cases of tetralogy of Fallot during surgical management. No severe myocardial injuries were noted during reperfusion than during the isehemic period, which was most probably due to the correction of the cardiac disorder, the presence of rich supply of endogenous free radical scanvagers. and the reduction of lung neutrophil sequenstration.
