目的分析法洛四联症的右心室造影特征及相关病理学基础.方法回顾性分析124例经手术证实法洛四联症造影检查情况.结果肺动脉狭窄按Gay氏分类:Ⅰ型62例,Ⅱ型31例,Ⅲ型6例,Ⅳ型25例;依Partiole氏分类:轻度狭窄71例(0.51～0.6),中度狭窄33例(0.41～0.5),重度狭窄20例(<0.4).室间隔缺损分为:嵴下型室间隔缺损116例,侧位片室上嵴通常表现为舌状或带状充盈缺损,部分与主动脉窦重叠,其上缘从后上向下前延伸,边缘光滑,轮廓清楚,构成缺损前缘;正位表现为椭圆形或圆形充盈缺损;嵴上型室间隔缺损(或称肺动脉瓣下型缺损)8例,表现室上嵴不显影.结论右心室造影在术前能够比较准确地确定肺动脉狭窄及室间隔缺损情况,在法洛四联症诊断和治疗中具有重要价值.

Objective To analysis the imaging findings of tetralogy of Fallot and related pathological basis. Methods The clinical,pathologic and right ventriculography findings of 124 tetralogy of Fallot which were confirmed by surgery were retrospectively aralyzed. Results 124 tetralogy of Fallot were separated into type Ⅰ 62, Ⅱ 31, Ⅲ 6, Ⅳ 25 by Gray's classification,and slight,midrange,severe stenosis were 71 (0.51～0.6) ,33(0.41～0.5) ,20(<0.4) by Partiole's classcification. As to ventricular septal defect(VSD) ,infra-cristal ventricular septal defect were found in 116/124 in which crista supravcntricalaris appeared as girdle-shaped filling defect in lateral position, suprac-ristal ventricular septal defect were found in 8/124 in which crista supraventricularis appeared as round filling defect in orthophoric position. Conclusions Right ventriculography can precisely display stenosis of pulmary and ventricular septal defect(VSD). It has great valne in diagnosis and surgical therapy of tetralogy of Fallot.
