摘要
本文采用同种血管片为材料,通过对法乐氏四联症患者22例的临床应用观察,对法乐氏四联症根治术右室流出道重建进行了进一步探讨。结果表明:同种带固有单瓣血管片重建右室流出道后,肺动脉反流明显减小,右室—肺动脉收缩压差低,血液动力学效果满意,术后恢复顺利。
The first stage work on the establishment of criteria for reconstruction of right ventricular outflow tract (RVOT) in radical trcatment of tetralogy of Fallot (TOF) had been finished in 1987. It shows that the width of transannular patch must be less than 1/2 of the circumference of normal pulmonary annulars and that the utilization of transannular patch with modified selfpericardium monocusp in reconstruction of RVOT is effective in decreasing pulmonary regurgitation.Based on the research mentioned above, we tried homograft of arterial(aortic or pulmonary) patch (HAOG, HPAG) with monocusp for the reconstruction of RVOT in radical treatment of TOF. The results show that transannular systolic pressure gradient and pulmonary regurgitation in this group is much less than that in the group of self-pericardium with monocusp, that-the technique of operation is no more complex, that patients recovered more quickly than before, and that problem of the limitation of the width of the transannular patch had been solved.No death in this group of 22 patients with TOF treated with HPAG or HAOG in radical operation. Pulmonary regurgitation in this group is very significantly less than that in the group of self-pericardium monocusp and right ventricular-pulmonary arterial pressure gradient is also obviously lessened. The hemodynamic results are very satisfactory.The conclusion is that HAOG or HPAG is of first choice in the reconstruction of RVOT and that modified self-pericardium with monocusp is an alternative if homograft is not available.
