目的:探讨经阴道超声诊断宫外孕的临床价值和效果。方法:使用超声诊断仪,经阴道探头频率715～1010MHz,经腹部探头频率315MHz。观察子宫大小、形态、内膜回声及厚度、宫腔情况,以及双附件区有无包块及包块的形态、大小、内部回声、有无妊娠囊,盆腔有无积液,同时记录包块的彩色血流分布情况,采用脉冲多普勒测量血流峰值流速及阻力指数。结果:本组病例中,输卵管妊娠58例,卵巢妊娠2例。全部病例经阴道超声检查均检出附件区包块,提示宫外孕58例(准确率96.7%),误诊2例(炎性包块l例、黄体血肿1例)。结论:检查过程中应注重与经腹部超声检查联合应用,并结合临床病史和HCG,避免发生误诊和漏诊。更为重要的的是影像学需要结合病史与临床表现,而不是孤立的B超诊断。
Objective: To investigate the clinical value and effectiveness of transvaginal ultrasound in the diagnosis of ectopic pregnancy. Methods: Using ultrasonic diagnostic apparatus, the transvaginal probe frequency 715 ~ 1010MHz, the abdominal probe frequency 315MHz. Observation of uterine size, morphology, endometrial echo and thickness, uterine cavity situation, and double attachment area with or without mass and mass form, size, internal echo, with or without gestational sac, pelvic fluid, while recording mass Of the color flow distribution, the use of pulsed Doppler flow peak velocity and resistance index. Results: In this group of cases, tubal pregnancy in 58 cases, 2 cases of ovarian pregnancy. Transvaginal ultrasound in all cases were detected in the annex area of the mass, suggesting that 58 cases of ectopic pregnancy (accuracy rate of 96.7%), misdiagnosed 2 cases (inflammatory mass l cases, luteal hematoma in 1 case). Conclusion: During the examination, we should pay attention to the combined application of transabdominal ultrasonography and clinical history and HCG to avoid misdiagnosis and missed diagnosis. More important is the need to combine medical history and clinical manifestations, rather than isolated B-ultrasound.
