摘要
目的彩色多普勒超声评价不同手术方式肺切除术后右心功能改变的临床意义.方法利用彩色多普勒超声于术前、术后3～5 d、术后8～10 d,检测28例肺叶切除、12例一侧肺全切除、10例肺楔形切除患者肺动脉平均压(PAMP),肺血管阻力(PVR)及右室每搏输出量(RVSV).结果肺叶及一侧肺全切除组在术后3～5 d右心后负荷(PAMP、PVR)较术前明显升高(P＜0.05),右室泵功能(RVSV)较术前明显降低(P＜0.05),全肺叶切除组较肺叶切除组改变更为明显(P＜0.05);肺楔形切除组右心后负荷及右室泵功能手术前后无明显变化(P＞0.05).术后8～10 d,肺叶切除组右心后负荷与右室泵功能恢复至术前水平,一侧肺全切除组组右心后负荷与右室泵功能仍然异常.结论彩色多普勒超声可以较为准确地评价不同方式肺叶切除术后右心功能状况,对于肺切除术后控制肺动脉压力,维护右心室功能有重要的指导意义.
Objective To study the changes of the function of right ventricle according to different operation ways after pulmonary resection by colour Doppler ultrasound.Methods Colour Doppler ultrasound were performed on 12 cases treated by pneumonectomy, 28 cases treated by lobectomy and 10 cases treated by wedge resection at pre-operation, post-operation 3rd to 5th day and post-operation 8th to 10th day. The changes of right cardiac afterload (PVR: pulmonary vascular resistance, PAMP: pulmonary artery mean pressure) and right ventricular pumping function (RVSV: right ventricular strock volume) were observed. Results PVR, PAMP evidently increased and RVSV decreased at post-operation 3rd to 5th day in cases treated by pneumonectomy and lobectomy(P<0.05). Cases treated by pneumonectomy had more changes than lobectomy. PVR, PAMP, RVSV returned to the level of preoperation in cases treated by lobectomy(P>0.05) and were still abnormal in cases treated by pneumonectomy(P<0.05)at post-operation 8th to 10th day. Cases treated by wedge resection had no differences in PVR, PAMP, RVSV between at pre-operation, post-operation 3rd to 5th day and post-operation 8th to 10th day(P>0.05).Conclusion Colour Doppler ultrasound could evaluate the function of right ventricle according to different operation ways after pulmonary resection, which contributes useful information to control pulmonary artery mean pressure and maintain function of right ventricle in clinic work.
