房室管畸形是一组复杂的先天性心脏畸形。本文收集了我院经手术治疗证实的10例。其中有9例在术前已诊断为房室管畸形。但未明确是完全型或部份型。现回顾分析认为:在房室管畸形的病例中,如果临床症状早而且重,肺动脉高压甚为明显,左室造影出现鹅颈征,二尖瓣返流等特征,并有较大的膜部室间隔缺损,则可提出完全型房室管畸形的诊断。若未显示鹅颈征(并非房室管畸形的反指征),应综合分析判断。合并四联症者甚少见,术前明确诊断较为困难。
Atrioventricular canal deformity is a complex set of congenital heart defects. This collection of our hospital confirmed by surgery in 10 cases. Nine of them had been diagnosed as atrioventricular canal deformity before surgery. But it is not clear that it is complete or partial. Are retrospective analysis that: in the case of atrioventricular tube deformity, if the clinical symptoms of early and weight, pulmonary hypertension is very obvious, left goose angiography goose neck, mitral regurgitation and other characteristics, and a larger membrane chamber Separation of defects, you can put forward the diagnosis of complete atrioventricular canal. If goose neck is not shown (not anti-indications of atrioventricular tube deformity), should be a comprehensive analysis to determine. The combination of tetralogy of disease is rare, a clear preoperative diagnosis is more difficult.
