链激酶冠状动脉内灌注能迅速溶解血栓性阻塞,约80%的病例有缺血区的再充盈。虽然这可明显缩短获得再充盈的时间间距,但心肌的不可逆损害还可能发生。用~(201)铊显象进行冠状动脉栓塞溶解术前后的对比证实,有些病例术后放射性缺损比术前有明显缩小,而另一些病例却只有很小或者没有新的摄取。冠状动脉内溶解术后~(201)铊的新摄取能否反映梗塞区的缩小,提示心肌获得恢复,尚待证实。本文通过用冠状动脉内注入~(201)铊的显象方
Streptokinase coronary perfusion can quickly dissolve thrombus obstruction, about 80% of cases have ischemic area refill. Although this can significantly shorten the time interval for obtaining refill, irreversible damage to the heart muscle can occur. Comparisons of ~ (201) thallium imaging before and after coronary artery embolization demonstrated that in some cases, the number of postoperative radioactive defects was significantly reduced compared with preoperative, while in other cases, there was little or no new uptake. Coronary intravascular lysis of ~ (201) thallium intake can reflect the reduction of infarct size, suggesting that the recovery of myocardium, yet to be confirmed. In this paper, intramuscular injection of ~ (201) thallium imaging square
