产前超声诊断隔离肺畸形及预后评估(1)
摘要:目的 探讨产前超声筛查隔离肺(PS)畸形及在其预后评估中的价值。方法 选择2015年1月~2015年12月期间在巴中市中心医院超声科筛出的13例PS胎儿为研究对象。回顾性分析胸腹腔内病灶的声像图特征,同时注意是否合并其它胎儿结构的异常,并随访临床预后情况。结果 13例PS胎儿,病灶均为单侧性,其中12例位于左侧,1例位于右侧;11例位于胸腔内,2例位于腹腔内;呈三角形或叶形;直径1.3~4.2cm;10例由胸主动脉供血,3例由腹主动脉供血。12例为单纯性PS,超声随访其中4例逐渐缩小消失,8例无改变,活产后均经影像学检查证实为PS;1例PS合并有胸、腹水,经引产后病理检查证实为PS。结论 产前超声是胎儿PS诊断的可靠方法,PS胎儿的预后主要与其是否有合并畸形及并发症有关。

Abstract:Objective To investigate the prenatal ultrasound screening of isolated lung (PS) malformation and in its prognostic value. Methods 13 cases of PS from January 2015 to December 2015 during the screening of fetal ultrasound,the Central Hospital of Bazhong city as the research object. We retrospectively analyzed the ultrasonographic features of thoracic and abdominal lesions,while paying attention to the presence of other fetal structures the abnormal,and follow-up clinical prognosis. Results 13 cases of PS fetuses,lesions were unilateral,12 cases located on the left side,1 cases located on the right side;11 cases in the chest,2 in abdominal cavity;a triangle or leaf shape;diameter 1.3 ~ 4.2cm;10 cases by thoracic aortic blood,3 cases the abdominal aorta blood.12 cases were treated with PS,including 4 cases of ultrasound follow-up reduced gradually disappeared,8 cases had no change, live postpartum were confirmed by imaging PS;1 cases of PS with chest,ascites,pathologically confirmed by autopsy for PS. Conclusion Prenatal ultrasound is a reliable method for the diagnosis of fetal PS,and the prognosis of PS fetus is mainly related to whether there are complications and complications.

隔離肺(Pulmonary sequestration,PS),又称为肺隔离症或副肺,由Price于1946年首次定义了此类肺疾患,表现为一团无功能的肺组织,无呼吸功能,与其相邻的正常肺组织分离,其血液供应主来自主动脉及其分支[1]。本病若引起胎儿胸腔腹腔积液等,预后较差,故产前早期诊断,并定期随访,对于判断PS胎儿的预后具有重要的意义。2015年1月~2015年12月,我科对13例PS胎儿的病历资料进行回顾性分析,旨在探讨产前超声诊断PS及在其预后评估中的价值,现报告如下。
1资料与方法
1.1一般资料 2015年1月~2015年12月,我科共筛出13例隔离肺畸形胎儿。超声诊断标准:胎儿胸腔内或腹腔内强回声或稍强回声团块、呈三角形或叶状、内部回声均匀、边界清,由体循环动脉或其分支供血[2]。孕妇年龄为21~43岁,平均(28.3±9)岁,发现隔离肺的平均孕周18~35 w,平均(26±4)w。

1.2 仪器与方法 使用Sequoia 512、GE-E8彩色超声诊断仪,频率为3.5~5 MHz腹部探头。检查时选用产科超声筛查软件,对胎儿进行系统产前超声筛查。最常用的检查体位是仰卧位,必要时侧卧位,若胎儿位置不正致无法观测病灶的血供情况时,应嘱孕妇起来走动一段时间后再检查。对胎儿的胸腹腔进行重点扫查。若发现胸腔及就近的腹腔出现异常回声病灶,观察病灶的声像图特征,尤病灶的血管供血来源情况,同时应仔细扫查,是否伴有其它异常胎儿结构的存在。活产病例,孕期每隔2w进行彩色多普勒超声复查病灶情况及是否有并发症,产后随访6-12个月;引产病例追踪其尸检结果。
2结果
13例PS胎儿,病灶均为单侧性,其中12例位于左侧,1例位于右侧;11例位于胸腔内,2例位于腹腔内;病灶呈三角形或叶形;直径1.3~4.2 cm,平均2.5 cm,,表现为强回声或偏强回声团块,与周边组织分界清楚,内部回声均匀;CDFI检查,10例由胸主动脉供血,3例由腹主动脉供血。12例为单纯性PS,超声随访其中4例逐渐缩小消失,8例无改变,活产后均经经核磁共振检查、CT造影剂增强扫描等影像学手段证实为PS,随访6~12个月,均未出现呼吸系统症状;1例PS合并病灶同侧胸腔腹腔积液,心脏受压移位,经引产后病理检查证实为PS。, http://www.100md.com(杨贵岚 王茜)
