冠状动脉瘘手术前后的二维脉冲多普勒超声心动图观察(附8例报告)

Two-dimensional and pulsed doppler echocardiography assessment of coronary artery fistula before and after operation

报告8例冠状动脉瘘,其中6例术前作了2D-PDE 检查。2D 特征是冠状动脉扩张,直径≥1.0cm,右室瘘的 PDE 特征是右室腔瘘口处连续性湍流,左室瘘的 PDE 特征是左室腔瘘口处舒张期湍流。随访了7例冠状动脉瘘术后病例,发现残余漏3例,术后病例心脏腔径均有不同程度缩小,但扩张的冠状动脉基本无变化。

In this paper,8 cases or coronary artery tistula were reported,6 cases of them underwent two-dimensional and pulsed doppler echocardiograyhy (2D-PDE) before operation.The feature of 2DE showed dilation of coronary artery (1.0cm in diameter). The features of PDE were as follows:A continuous turbulent flow within the right ventri- cuar cavity at the site of draining orifice was noted in right ventricular fistula.A diastolic turbulent flow within the left ventricular cavity at the site of draining orifice was noted in left ventricular fistula.7 cases were followed up postoperatively.The dimensions of cardiac cavity were reduced variedly in all cases.However,there was no change for dilated coronary artery.Residual fistula was found in 3 cases.
