摘要
目的：评估四腔心切面显示胎儿食管的可行性。方法：对423例行系统胎儿超声检查的胎儿通过获取四腔心切面（心尖四腔心切面和/或胸骨旁四腔心切面和/或心底四腔心切面）观察食管回声，并记录胎位，测量胎儿心脏距探头最前点至探头的垂直距离。结果：423例行系统筛查的胎儿，95.0%（402/423）的胎儿能通过四腔心切面显示胎儿食管回声。四腔心切面中以胸骨旁四腔心切面显示食管最佳，P<0.05。产前超声检查通过四腔心切面显示胎儿食管，胎位及胎儿心脏与探头间的距离是影响因素。结论：产前超声通过四腔心切面显示胎儿食管是可行的，各种四腔心切面中以胸骨旁四腔心切面显示食管为优。
Abstract
Objective: To evaluate the feasibility of using four-chamber view to assess fetal esophagus. Methods: All patients(423 cases) underwent prenatal ultrasound examination to get four-chamber view of esophagus(apical four-chamber view or parasternum four-chamber view or cardiac base four-chamber view). Fetal position and distance between fetal heart and the probe were recorded. Results: Among 423 cases, 95.0%(402/423) cases can display esophagus with the four-chamber view. Among all four-chamber views, parasternum four-chamber view was the best way to display fetal esophagus(P<0.05). Fetal position and the distance between fetal heart and the probe were influence factors. Conclusion: It is feasible to display fetal esophagus with the four-chamber view. Parasternum four-chamber view is the best way to display fetal esophagus among three four-chamber views.
