| 摘 要： | 目的 探讨肺动脉高压(PAH)患者上腔静脉(SVC)血流频谱变化的特点. 方法心脏介入手术和心脏外科手术患者45例,男26例,女19例,平均年龄(29±21.5)岁,右心导管检测肺动脉收缩压.按照肺动脉收缩压(PASP)分为肺动脉压正常值对照组(PASP＜30 mmHg,n=8)、轻度肺动脉高压组(30 mmHg≤PASP＜50 mmHg,n=18)、中度肺动脉高压组(50 mmHg≤PASP＜75 mmHg,n=13)、重度肺动脉高压组(PASP≥75 mmHg,n=6).同时采用彩色多普勒超声仪经右侧锁骨上窝探测上腔静脉,记录平静呼吸时上腔静脉的频谱曲线,测量同一呼吸周期中频谱曲线各波峰值及速度时间积分(VTI),计算其呼吸变化率. 结果肺动脉压正常对照组上腔静脉血流频谱,收缩期S波、舒张期D波随呼吸波动明显.与肺动脉压正常对照组比较,轻度肺动脉高压组上腔静脉血流频谱S波、D波振幅无显著性差异(P＞0.05).中、重度肺动脉高压组上腔静脉血流频谱S波、D波随呼吸变化振幅减低,而离心方向的室缩波VR、房缩波AR波振幅增高(P＜0.05),部分患者频谱形态发生变化. 结论上腔静脉血流频谱随呼吸变化是评价肺动脉压力的有效指标,可为肺动脉高压的临床诊断提供无创血流动力学指标. |
