联体儿的影像学评估及应用

目的：通过对以往病例的回顾，发现适用于联体儿诊断的影像学检查方法，为手术做准备，提高术后生存率。方法：观察以往病例的影像学检查，对照手术及病理进行比较。结果：6例联体儿中5例胸腹联体，1例坐骨联体，5例胸腹联体均为肝脏及胸骨融合，所有患儿均有不同程度的先天性心脏病， 1例坐骨联体两个患儿共用一条直肠，手术结果与影像诊断大致一致。结论：通过适用的影像学检查，能够全面的了解联体儿内部的结构异常情况，对手术的难度、手术的选择、术前准备、预后评估有重要意义。

The evaluation and diagnosis of conjoined twins through imaging

Objective: To find the best imaging examinations for conjoined twins by reviewing the previous cases. Methods: The imaging exams from the six previous cases were analyzed retrospectively, and the results were compared in relation to pathology and operative result. Results: There were five pairs of thoraco-omphalopagus conjoined twins among the six cases, and the other pair was ischiopagus. The five thoraco-omphalopagus cases all had conjoined livers and portions of the chest bones fused. All the patients of the six cases had different kinds of congenital heart disease. The ischiopagus conjoined twins had the common rectum. The operation results match with the imaging diagnosis. Conclusion: The inside abnormality of conjoined twins can be better understood by using suitable imaging exams, which has important significance for the evaluation of the operation and the overall prognosis
