1、胎儿水囊状淋巴管瘤的超声诊断价值作者:张宗美向伦祥张友志吴强单位:【摘要】目的探讨超声在诊断胎儿水囊状淋巴管瘤屮的诊断价值。方法回顾分析胎儿23例水囊状淋巴管瘤超声声像图特点,并经引产后病理证实。结果23例患胎儿水囊状淋巴管瘤的孕妇均在12周〜28周,经超声常规检查时发现。瘤体最大约8.9cmxl6.3cmx9.8cm,最小约1.0x0.9cmx0.5cm。位于颈部12例,上肢1例,肩背部1例,胸前2例。并发胸腔积液6例,腹腔积液9例,胸腹腔均积液4例,皮下水肿5例,心包腔积液1例。声像图特征:胎儿头及颈部围绕一囊肿,呈多房性,壁较厚或薄,内可见
2、分隔,无分隔者较小;位于肢体可呈蜂窝状。结论超声可诊断胎儿水囊状淋巴管瘤,对临床医师评估胎儿预后、指导临床处置有重要的临床意义。【关键词】超声诊断;胎儿;水囊状淋巴管瘤Diagnosticvalueoffetalwater-cysticlymphangiomawithultrasonographyZHANGZong-meiXIANGLun-xiangZHANGYou-zhiWUQiangDepartmentofultrasound,ChongqingThreeGorgesCentralHospital,Chongqing404000,China[

7、罕见,仅占胎儿异常的2〜3%[1]0现将在我院发现且经病理证实的23例水囊状淋巴管瘤报告如下。资料与方法一、研究对象本文23例均来源于2001年1月—2008年1月来我科常规进行产前超声检查的孕妇,年龄21〜38岁,平均28.8岁。孕周12〜28周,平均22周。初次妊娠8例,第二次妊娠13例,第三次妊娠2例,其中9例有自然流产史,4例胎死宫内史,2例畸形胎儿史(一例为脑积水,一例为脊柱裂)。超声检查次数:18例为第1次,5例为第2次。二、仪器与方法采用ViVid7和SSA-240型超声诊断仪,频率为3.5MHz。患者取仰卧位或侧卧位,
8、充分暴露腹部,对胎儿做常规检查,重点观察胎儿头部、颈部、躯干及四肢软组织情况、囊肿大小、形态、内部回声、胸腹腔及心包腔有无积液,胎儿畸形
