Vasa previa describes vessels that are unprotected by Wharton's jelly and traverse over or near the endocervix. Rupture of membranes or labor increases the risk of vessel rupture, followed by rapid fetal exsanguination. Learners are often taught to manage this condition by case scenarios and simulations. We present a case of type I vasa previa where intraoperative photographs demonstrate the potentially catastrophic rupture of membranes into the unprotected fetal vessels during a scheduled cesarean delivery. We recommend using intraoperative photographs to educate learners and counsel patients on the potential acuity inherent to this condition.
前置血管是指未受华通胶保护且跨越宫颈内口或在其附近走行的血管。胎膜破裂或临产会增加血管破裂的风险,继而导致胎儿迅速失血。通常通过病例和模拟向学习者传授这种情况的处理方法。我们报告一例I型前置血管病例,术中照片显示在择期剖宫产时,胎膜意外破裂,致使未受保护的胎儿血管暴露。我们建议使用术中照片对学习者进行培训,并就这种情况的潜在严重性向患者提供咨询。
