本文总结北京心肺血管中心自1985年4月至1990年5月5年对133例室间隔缺损患儿,应用非侵入性及侵入性方法对照研究,对肺动脉收缩压、肺动脉平均压及肺血管阻力估测的结果。在某些先天性心脏病患儿,由于存在大量左向右分流使肺动脉压力上升。如肺动脉压持续增高则肺小动脉逐渐发生中层及内膜肥厚与纤维化等,管腔变窄堵塞,此时不但肺动脉压严重升高且肺血管阻力亦增加,丧失手术时机,或术后肺血管病变继续进展,导致右心衰竭终至死亡。因此及时,有时需重复、多次于术前、术后测量肺动脉压力及肺血管阻力,对决定手术及估评预后至关重要。采用非侵入性方法可解决上述问题。本研究采用二维超声心动图合并多普勒技术估测肺动脉压力及肺血管阻力取得较好效果。
This article summarizes the Beijing Cardiovascular Center from April 1985 to May 1990 five years 133 cases of ventricular septal defect in children with non-invasive and invasive method of control study of pulmonary artery systolic blood pressure, pulmonary artery mean pressure and pulmonary vascular resistance Estimated results. In some children with congenital heart disease, pulmonary pressure rises due to the large left-to-right shunting. Such as pulmonary hypertension continued to increase the gradual occurrence of pulmonary arterioles middle and endometrial hypertrophy and fibrosis, lumen narrowing and obstruction, this time not only a serious increase in pulmonary arterial pressure and pulmonary vascular resistance also increased, loss of timing of surgery, or postoperative lung Vascular disease continues to progress, leading to the death of right heart failure. Therefore, timely, and sometimes need to be repeated, many times in preoperative and postoperative measurement of pulmonary artery pressure and pulmonary vascular resistance, the decision of the operation and assessment of prognosis is crucial. Non-intrusive method to solve the above problems. This study used two-dimensional echocardiography combined with Doppler to assess pulmonary artery pressure and pulmonary vascular resistance achieved good results.
