川崎病患者肺静脉血流频谱改变及其临床价值

应用多普勒超声心动图观察21例川崎病患者急性期和恢复期肺静脉血流频谱（PVF，含Vs、VD、S／D、D／S、VTIs、VTID、SFF、DFF、Ts、TD、Ts＋D）改变，与21例健康儿童对照。发现：川崎病急性期VD明显低于对照组，致S／D＞1。VTID亦明显减低。DFF相应减低，恢复期VD重新增高，S／D＜1，VTID亦恢复。时间指标各组间无明显变化。表明川崎病急性期存在可逆性左室舒张功能障碍，PVF可动态反映这一改变。

THE CHANGE OF THE PULMONARY VENOUS FLOW PATTERNS IN PATIENTS WITH KAWASAKI DISEASE AND ITS CLINICAL SIGNIFICANCE

In order to investigate the left ven tricular diastolic function (LVDF) of children with Kawasaki disease (KD), 21 cases were examined by pulmonary venous flow (PVF) in acute and conva lescent phases of disease, and 21 normal children were used as controls (NC). The following parameters were obtained: 1. Vs,Vd, S/D, 2. VTIs,VTID,SFF. DFF, 3 Ts, TD, TS D.Results: 1. Compared with NC, Vs was no significant change in acute phase, but VD was significantly decreased (P<0. 01), and S/D was significantly increased (P<0. 05 ), in the convalesecent phase, Vs was nochange, VD was higher. S/D was decreased (P<0. 05). 2. VTIs in acute phase group was not significantly different than NC(P>0.05). VTID and DFF were significantly decreased (P<0.05, P <0.01respectively ). However, in convalescent phase, all of the VTI parameters were not significantly differ ent compared with those in NC (P<0.05). 3. Duration time had no significant change among allgroups. Conclusion: there were reversible changes of left ventricular diastolic disfunction in KD acutephase, PVF is valuable in assessment of LVDF for children with KD.
