摘要
目的评价经阴道Ｂ超早期诊断宫颈机能不全及早期治疗的效果。方法测量２９例宫颈机能不全者的宫颈长度，观察有无内口开大的征象，并与５０例相同孕周的正常妊娠者进行比较。结果正常妊娠者的宫颈长度为３６±９ｍｍ，宫颈机能不全者的宫颈长度显著短于正常妊娠者，并出现内口开大的征象。结论宫颈长度较正常妊娠妇女缩短＞３０％，伴有内口开大的征象是宫颈机能不全的重要表现。早期进行宫颈环扎术的孕妇预后良好。
Objective To evaluate the efficacy of vaginal ultrasonography for early diagnosis of cervical incompetency and the result of early treatment.Methods During a one year period in a single referral hospital,all patients(29)with diagnosis of cervical incompetence were considered candidates for this study.50 normal pregnant women as a control,whose gestational weeks were between 14￣28 weeks.Cervical change and length of these women were measured and compared to study group. Rusults The length of cervix in control group were 36±9 mm,that were significantly shorter than control group.
