摘    要:目的应用彩色多普勒超声心动图(彩超)术前判断法洛四联症(TOF)患者术后是否会出现低心排血量综合征(LCOS),预测手术效果。方法2004年1月至2007年1月行彩超检查并经矫治术治疗的TOF患者60例,按术后有无发生LCOS将病例分成2组,即低心排组(Group1)和无低心排组(Group2),每组资料均于术前行彩超检查,测量室间隔缺损左向右分流血流速度(L-Rv)及持续时间(L—Rt),右向左分流血流速度(R—Lv)及持续时间(R—Lt),计算AO/LVd、AO/LA比值,将2组数据作统计分析,判断各测值与术后出现LCOS的相关性。结果本组资料中,术后出现LCOS25例(Group1组),占41.67%,其中死亡22例,死亡率88.00%;术后无低心排组35例(Group2组),占58.33%,其中无1例死亡,术后死亡率Group1组明显高于Group2组(P〈0.01)。结果表明R—Lv、R—Lt、AO/LA是TOF术后LCOS发生的主要影响因素,且都是危险因素,ORR-Lv=1.068,ORR-Lt=1.026,ORAO/LA=8.828,并建立一判别函数,其中AO/LA影响最大,R—Lv其次,R—Lt最小。结论彩超测量TOF患者室间隔缺损右向左分流血流速度和持续时间,计算AO/LA比值,根据判别函数,可判断术后是否会出现LCOS,是估计TOF严重程度、预测手术效果的一种简单有效的方法。

关 键 词:法洛四联症  彩色多普勒超声心动图  彩色M型超声心动图

Abstract:Objective Evaluate the serious of tetralogy of fallot and predict which patient would appear low cardiac output syndrome(LCOS)after surgery using the velocities and timings across the large VSD mainly by echocardiography.Methods Between january 2004 and january 2007,60 patients were performed with complete transthoracic echo-doppler examination using combined two-dimensional color M-mode and color doppler flow imaging.All patients were underwent a surgical procedure.Measuring the velocities and timings acro...
