摘要 目的:评价16层螺旋CT在房性心律失常射频消融术前检查的应用价值。方法:房性心律失常患者42例,采用西门子16层CT对所有病例行增强扫描,常规原始数据薄层重建后进行图像重组,方法有MPR、MIP、VRT或SSD等,观察左心房、肺静脉分支及食管空间关系,明确肺静脉分支的数目、大小及走向和左心房腔内肺静脉开口,在轴位图像或二维重组(MPR、MIP)图像上测量各肺静脉口内径及食管与左心房后壁接触的长度。结果:所有病例均可清楚显示左心房、肺静脉分支及食管解剖细节,左心房充盈良好,食管沿左心房后壁走行,可见左心房与食管间脂肪垫;肺静脉根部测量直径平均值:右上肺静脉(12.8±2.5)mm,右下肺静脉(13.1±2.6)mm,左上肺静脉(12.0±1.8)mm,左下肺静脉(10.6±2.4)mm,左心房与食管平均接触长度为(50±16)mm。结论:16层螺旋CT增强扫描可以清楚显示左心房、肺静脉分支及食管的空间位置,肺静脉分支的数目、大小及走向清楚,肺静脉开口直径、食管与左心房接触长度测量准确,是房性心律失常射频消融术前检查的重要手段。
