METHODS From October 2004 to January 2008, 24 patients with complex congenital heart disease underwent RHB. The dignoses of patients included tricuspid atresia, single ventricle, and so on. Among them, 8 cases were found ectopia cordis. Opreation precedure included bidrectional Glenn shunt (19 cases) and total caval pulmonary connection (TCPC,5 cases). In the 24 cases, 16 patient underwent off-pump operation. RESULTS Total hospital mottality was 4.2%.

2004年10月至2008年1月，采用右心旁路手术治疗复杂先天性心脏病共24例（病种包括三尖瓣闭锁、单心室等，其中心脏位置异常8例）。19例行双向格林术，5例行全腔静脉-肺动脉吻合术。24中16例在非体外循环下实施，2例双向格林术术后再次手术。

The finger at the left is holding a markedly thickened right ventricular free wall below the tricuspid valve, and the finger at the right is holding the interventricular septum.

左边手指提着的是明显变厚的位于三尖瓣下的游离心室壁，而右边手指提着的是室间隔。

The following values was measured: angle of cusp line between the second and third molar, impact state and depth, distance from Rickett's Xi to distal cusp of third mandibular molar along the occlusal plane, anterior border of ramus to the third mandibular molar, distance from projection of distal contact point of maxillary third molar to intersection of pterygoid vertical on occlusal plane.The change between pre-and post-treatment was calculated and analyzed with SPSS10.0 software package.α angle, Xi-LTM, R-LTM, R-LTM were tested with independent-sample t test, impact state and depth was tested with Chi-square test. Influence of age on the values was also evaluated.

测量治疗前后的第二、第三磨牙牙尖连线角度、阻生状态和深度，Rickett's Xi点到下颌第三磨牙远中尖距离、下颌支前缘到第三磨牙远中尖距离、翼上颌裂切线到上颌第三磨牙后缘的距离及上、下磨牙的前移量，计算治疗前后各变量的差值，采用SPSS10.0软件包进行统计学分析，α角、Xi-LTM、R-LTM、R-LTM用t检验，阻生状态和深度用χ^2检验，比较年龄因素对各指标的影响。

The Phase I tip has simple straight swept or tapered shape, the curve change of the platform is included during Phase Ⅱ, and the geometry of the Phase Ⅲ tip is extended to anhedral modification.

第一层次的桨尖形状为直线后掠或尖削，第二层次包括桨尖平面的曲线变化，而第三层次进入到下反桨尖这种三维变化。

The respiratory pulsatility of flows in portal vein were studied,and the pulsatility index and the correlative index between the PI and the quantity of TR were calculated.

在正常呼吸的情况下观察门静脉血流频谱的波动性，并计算血流波动系数以及波动系数与三尖瓣返流量的相关系数。

Coning and quartering method: put the sample onto the steel plate in the form of a cone; each scoop shall be inserted from the top of conical to make it spread along the top evenly, and pay attention not to misplace the center of cone; do it at least 3 times and mixed thoroughly; then flatten the top and use the cross plate from top to bottom to divide into 4 equal segments, randomly take out 2 oppositesegments and do it repeatedly for several times and finally divided into not less than the minimum retained quantity.

圆锥四分法：将样品置于已用样品刷好的钢板上，堆成圆锥形，每铲由圆锥顶尖落下，使其均匀地沿锥尖散落，注意勿使圆锥中心错位，如此反复至少移堆三次，使其充分混匀，然后将锥尖压平，用十字板自上插下，分成四等份，任取两个对角的等份，重复操作数次，缩分至不少于最少留样量。

Results Fifty-eight (93.5%) cases SVA were preoperatively discovered by echocardiography, while 2 (3.2%) misdiagnosed as tetralogy of Fallot and tricuspid regurgitation and 2 (3.2%) missed diagnosis.Accompanying teratisms included frequently ventricular septal defect (33 cases, 53.2 %) and aortic valve dysplasia(11 cases, 17.7%).The rupture site and the drainage chamber were essentially consisted with surgery,while the size of VSD measured by echocardiography was significantly smaller than that measured in operation.

结果 62例患者中，术前超声诊断Valsalva窦瘤破裂58例(符合率93.5%)，误诊为法洛四联症、三尖瓣反流各1例(3.2%)，漏诊2例(3.2%)；常见的合并畸形有干下室间隔缺损(33例，53.2%)、主动脉瓣发育不良伴重度主动脉瓣关闭不全(11例，17.7%)；超声报告窦瘤部位及破人腔室与手术结果一致，超声所测室间隔缺损大小明显低于手术所见。
