摘　　要：目的寻求一种便捷、准确诊断前置胎盘的超声检查途径。方法对62例临床疑有且经常规腹部超声检查诊断为前置胎盘的患者行经会阴部超声检查。将前置胎盘分为前壁型、后壁及侧后型三型,并与剖宫产后结果对照。结果剖宫产术后证实,前壁型前置胎盘23例,经腹部与经会阴部超声检查均做出了准确的诊断,诊断符合率均为100%,两种方法比较差异无统计学意义。后壁和侧后型前置胎盘39例,经腹部超声检查诊断为25例,诊断符合率为64.1%;经会阴部超声检查诊断36例,诊断符合率为92.3%。两种方法比较,经会阴超声检查后壁和侧后壁型前置胎盘符合率明显优于经腹部超声检查(P<0.05)。结论经会阴超声检查可以较清晰地显示宫颈管,明确宫颈内口与胎盘位置的关系,提高了后壁与侧后壁型前置胎盘诊断的准确率,给临床提供了处理依据。经会阴超声诊断前置胎盘方法简便,图像清晰且准确,值得临床推广。Objective To seek a convenient and accurate route for ultrasound diagnosis of placenta previa. Methods Sixty- two patients with placenta previa confirmed by conventional uhraosonography were enrolled in this study, then they were examined by transperineal ultrasound. The placenta previa were divided into autetheca type, posterior wall type and lateral posterior wall type, the results were compared with those after cesarean section. Results After cesarean section, there were 23 cases of antetheca, the transabdominal and transperineal uhrasound made accurate diagnosis, the diagnostic accuracy rate was 100% , there was no significant difference between the two methods. While there was 39 cases of posterior wall and lateral posterior wall type, 25 cases were diagnosed by trasnsabdominal ultrasonography, the diagnostic accuracy rate was 64.1% , and 36 cases were diagnosed by transperineal uhrasonography, the diagnostic accuracy rate was 92. 3%, there was significant difference between the two methods （P 〈 0.05 ）. Conclusion Transperineal ultrasound can clearly display the cervical canals, identify the relationship between cervix endostoma and placenta location, and improve the diagnostic accuracy rate for posterior wall and lateral posterior wall type of placenta previa, it is worth spreading in clinic for it is a convenient and accurate method in diagnosis of placenta previa.
