摘  要:目的探讨胎儿下腔静脉离断产前超声声像图特征和有效诊断切面,以提高其产前超声诊断准确率。方法回顾性分析我院2006年1月至2010年5月诊断的10例下腔静脉离断胎儿(其中7例经引产后尸体解剖证实)产前超声声像图,与正常超声声像图对比,总结其产前超声声像图特征及有效切面。结果 10例下腔静脉离断胎儿,9例合并严重心内结构畸形,7例合并心外结构畸形(其中5例合并内脏反位)。本组10例下腔静脉离断胎儿产前超声声像图均表现为四腔心切面异常(奇静脉扩张)、上腹部横切面异常(正常下腔静脉不能显示)、胸腹部斜冠状切面异常[离断的下腔静脉异位连接于奇(半奇)静脉并穿过膈肌连于腔静脉]及右心房纵切面异常(肝上段下腔静脉入右心房,肾上段肝段间的下腔静脉缺失并离断)。结论下腔静脉离断常合并心内、外结构畸形。下腔静脉离断胎儿在四腔心切面、上腹部横切面、胸腹部斜冠状切面及右心房纵切面上均有特征性超声声像图表现。识别下腔静脉离断特征性超声声像图表现可明显提高其产前超声检出率和诊断准确率。Objective To investigate ultrasound characteristics and effective diagnosis views of interruption of the inferior vena cava.Methods Between January 2006 and May 2010,10 fetuses were diagnosed as interruption of the inferior vena cava by ultrasound in our hospital.Seven cases of them were confirmed by autopsy.Their ultrasound images were retrospectively reviewed and compared with normal ones.Results Among the ten fetuses,9 were complicated with severe cardiac malformations and 7 were complicated with outside cardiac malformations(including 5 with situ inverse).For all the 10 cases,dilated venae azygos could be found in four-chamber view,normal inferior vena cava could not be found in the upper abdominal view,inferior vena cava connected with venae azygos or semiazygos vein in transthoracoabdominal coronal view and only the above liver portion of inferior vena cava could be found in the longitudinal section of right atria view.Conclusions Interruption of the inferior vena cava is always complicated with cardiac and outside cardiac malformation atria view.And the abnormalities can be identified in the following ultrasound views: four-chamber view,upper abdominal view,transthoracoabdominal coronal view and longitudinal section of right atria view.Identification of these ultrasound characteristics can improve the prenatal detection rate of interruption of the inferior vena cava.
