超声心动图评价胸腔积液对肺静脉血流的影响

目的：探讨胸腔积液对肺静脉血流影响。方法：选取结核性胸腔积液患者61例,以积液量分为四组,A组,中等量右胸腔积液15例;B组,中等量左胸腔积液21例;C组,大量右胸腔积液15例;D组,大量左胸腔积液10例。测量右肺上静脉血流速度。结果：抽液后A、B、C组各指标无变化;D组收缩期峰值流速升高,P〈0.05,有显著性差异。结论：左胸腔大量积液后,右肺上静脉收缩期峰值流速减低。

Echocardiography assessment for pleural effusion effect on blood speed of pulmonary vein

Objective：To study the pleural effusion effect on blood speed of pulmonary vein. Methods：61 cases with pleural effusion were divided into group A （15 cases ）with middle volume effusion in right pleura cavity,group B （21 cases） with middle volume effusion in left pleura cavity,group C （15 cases） with large volume effusion in right pleura cavity and group D （10 cases） with large volume effusion in left pleura cavity. Right superior pulmonary vein blood speed including systole and diastole was measured. Results：After effusion was drawn,indexes of A,B and C group did not change. Right superior pulmonary vein systole blood speed of D group rised,P〈0.05. Conclusion：With left pleura cavity large volume effusion,right superior pulmonary vein systole blood speed lower.
