本文总结了11983年以前29年中71例次的脑积水畸胎的分娩。发病率为0.046％。产前诊断者37例次(52.1％)。临床上除腹部或阴道检查时发现羊水过多、胎头过大需注意有脑积水畸胎外,遇异常胎位或胎先露时也需提高警惕。凡既往有脑积水畸胎分娩史B型超声仪的使用,可在头颅外形未增大前根据胎头一侧的侧脑室宽度与大脑半球宽度的比值(LVW/HW)>0.65时确定诊断,更具优越性。脑积水畸胎孕产期并发症中以臀位最多(29.58％),以子宫破裂(4.8％)最严重。一旦确诊后应及早终止妊娠,若发现较晚则应以考虑母亲安全的前提下,使其阴道分娩,在宫口开大3cm后,用腰椎穿刺针刺入脑室,放出液体,以防分娩时子宫破裂。
This article summarizes the delivery of 71 cases of hydrocephalus teratogenic in the 29 years prior to 11983. The incidence was 0.046%. Prenatal diagnosis 37 cases (52.1%). Clinically, in addition to abdominal or vaginal examination found polyhydramnios, fetal head too large need to pay attention to hydrocephalus teratogenic, abnormal fetal position or fetal exposure also need to be vigilant. Where previous history of teratogenic delivery B-type ultrasound system can be diagnosed before the appearance of the skull is not increased according to the side of the fetal head side of the width of the cerebral ventricle and the ratio of the width of the hemisphere (LVW / HW)> 0.65 to determine the diagnosis , More superiority. In the hydrocephalus teratogeny, the breech position was the most (29.58%) and the uterine rupture was the most serious (4.8%). Once the diagnosis should be terminated early pregnancy, if found later should be considered the premise of the mother under the premise of vaginal delivery in the cervix open 3cm, with the lumbar puncture needle into the ventricle, the release of liquid to prevent childbirth Uterine rupture.
