目的探讨快速准确地诊断胎盘位置的方法,为临床争得更多的治疗时间,尽最大限度保障母婴平安。方法对89例妊娠晚期的阴道出血、临床可疑前置胎盘的孕妇行腹部、阴道或会阴超声检查,判断前置胎盘与宫颈的位置。结果腹部检出70例,符合率为89%,误漏诊7例,模糊诊断2例,经阴道或会阴超声检查出78例,符合率为100%(89例中有11例为其他妊娠出血疾病)。结论会阴或阴道超声检查对于晚期妊娠前置胎盘位置的诊断优于腹部超声检查,大大降低了误漏诊率,为临床的一些诊疗操作提供精确的胎盘位置,争得了处理时间,对减少围产期孕妇和胎儿病死率有重大价值。同时也总结了腹部、阴道及会阴超声检查的不足之处,从而更好地利用它们有利于临床诊断的方面,避免和完善不足之处。
Objective To explore a rapid and accurate method for the diagnosis of placenta location, to clinically gain more treatment time, to maximize the safety of mother and child. Methods 89 cases of vaginal bleeding in late pregnancy, clinical suspicious placenta previa abdominal, vaginal or perineal ultrasound examination to determine the location of placenta previa and cervix. Results In the abdomen, 70 cases were detected, the coincidence rate was 89%, 7 cases were misdiagnosed, 2 cases were vaguely diagnosed, 78 cases were examined by vaginal or perineal ultrasonography, the coincidence rate was 100% (11 of 89 cases were other pregnancy bleeding diseases ). Conclusion Perineal or vaginal ultrasonography is superior to abdominal ultrasonography in the diagnosis of placenta previa in late pregnancy, which greatly reduces the misdiagnosis rate and provides accurate placenta position for some clinical diagnosis and treatment. It has obtained the treatment time and reduced the perinatal period Pregnancy and fetal mortality have great value. It also summarizes the inadequacies of the abdominal, vaginal, and perineal ultrasound exams to better utilize the aspects that benefit them for clinical diagnosis and to avoid and refine deficiencies.
