| 目的 探讨提高未破裂型异位妊娠超声诊断率的方法及应用价值。方法 单独及联合应用已经获得的各超声诊断指标,对疑似异位妊娠的139个附件区厚壁小囊性灶进行前瞻性预测。所有病灶经手术病理及临床长期随访确诊,其中异位妊娠病灶(妊娠囊型)61个,卵巢黄体78个。将各超声指标的预测结果与金标准对照,对各超声指标诊断价值进行评价。结果 囊壁回声高于或等于内膜回声、囊壁回声高于卵巢实质回声、囊肿周围未见小卵泡回声作为诊断异位妊娠孕囊的阳性指标,其各自的敏感度分别是86.89%、93.44%及96.72%,特异度分别为93.59%、85.90%及70.51%,且联合应用两个指标的敏感度为98.36%,特异度为94.87%。结论 判断附件区囊肿与卵巢的关系及比较囊壁回声对异位妊娠有很高的诊断价值。 |

| Objective To evaluate the methods for improving diagnostic ratio of unruptured ectopic pregnancy with ultrasonography. Methods A total of 139 patients of small adnexal cysts with thick wall were predicted respectively with sonographic indexes. All patients (61 with unruptured ectopic pregnancy and 78 with small corpusluteum) were confirmed postoperatively or with long-term follow up, and the results were compared. Results The diagnostic sensitivity of with hyperecho or isoecho compared with endometrium, hyperecho compared with ovarian tissue, adnexal cyst without small follicle around was 86.89%, 93.44% and 96.72%, and the specificity of three predictors was 93.59%, 85.90% and 70.51%, respectively. Two sonographic indexes together had a sensitivity of 98.36% and a specificity of 94.87% for diagnosing ectopic pregnancy. Conclusion Observing the relation of adnexal cyst and ovarian and the echogenic of cyst wall are specific and sensitive for the diagnosis of ectopic pregnancy. |
