摘要 小儿先天性心脏病48例,其中伴肺动脉高压(PH)32例,应用99mTc标记大分子聚合白蛋白(MAA)行肺灌注显像,以右侧和左侧卧位时右肺与左肺放射性计数的比值rt/lt来随访术后肺动脉压力.结果表明rt/lt值能定性、定量地评价肺动脉压力,动物实验示该法重复性好,并提示术后恢复的一些影响因素,对选择手术时机及术后随访疗效颇有临床实用价值. Abstract Pulmonary perfusion imaging with 99mTc labelled macroaggregated albumin (MAA) was performed in 48 cases of congenital heart diseases of children, including 32 cases with pulmonary hypertension (PH). The change in the total count ratio of the right lung against the left lung between right and left lateral decubitus positions (rt/lt) was used to assess the pulmonary arterial pressure postoperatively. The results showed that rt / lt ratio could qualitatively evaluate the pulmonary arterial pressure. The reproducibility of rt/ lt ratio was quite good in experiments with rabbitS. Some factors which affected the recovery of PH after operation have been discussed in this paper.
