目的:探讨容积对比成像(VCI-C平面)及经阴彩色多普勒超声诊断异位妊娠的特征性依据,提高宫外孕诊断的准确性。方法:对188例疑似早期异位妊娠的患者测定血HCG,进行二维经阴经腹彩超及VCI-C平面、TUI检查,测定子宫内膜厚度及血流分布,测量子宫动脉及滋养动脉血流频谱,并做比较。结果:188例中及时确诊183例。①附件区妊娠囊内可见胎儿或者卵黄囊,有17例有胎心搏动,占9.0%。②Donut征(输卵管环),其中98例有Donut征,占52.1%。③附件区内可探及混合性包块,有时伴有少量积液60例,占31.9%。④另有部分不典型病例仅表现为盆腔积液8例,占4.3%。诊断符合率97.3%。结论:经阴(TVS)及经腹(TAS)结合CDFI,能准确迅速地取得异位妊娠(EP)的证据,结合血HCG进行生化学的诊断是早期诊断EP的较好手段,VCI-C平面超声成像结合3D重建信息量大,提高了对比分辨率与信噪比,比二维提供更多信息。
Objective: To investigate the characteristic evidence of volume contrast imaging (VCI-C plane) and transvaginal color Doppler ultrasound in diagnosis of ectopic pregnancy, and to improve the accuracy of ectopic pregnancy diagnosis. Methods: A total of 188 patients with suspected early ectopic pregnancy were enrolled in this study. Plasma HCG levels were measured by 2D transvaginal ultrasonography, VCI-C and TUI examination. Endometrial thickness and blood flow distribution were measured. Uterine artery and nourishing artery blood Stream spectrum and compare. Results: 183 cases were diagnosed timely in 188 cases. ① Annex area gestational sac visible fetal or yolk sac, there are 17 cases of fetal heart beat, accounting for 9.0%. Donut sign (tubal ring), of which 98 cases have Donut sign, accounting for 52.1%. Â ’¢ annex area can be explored and mixed mass, and sometimes accompanied by a small amount of effusion 60 cases, accounting for 31.9%. ④ Another part of atypical cases showed only pelvic fluid in 8 cases, accounting for 4.3%. Diagnostic coincidence rate of 97.3%. Conclusion: Evidence of ectopic pregnancy (EP) can be obtained accurately and rapidly by combining TVF and TAS with CDFI. The biochemical diagnosis of HCG combined with blood is a good way to diagnose EP early. VCI-C Planar ultrasound imaging combined with 3D reconstruction of large amount of information to improve the contrast ratio and signal to noise ratio, provide more information than two.
