An analysis of the sonograms of 60 patients with a surgically confirmed diagnosis of ectopic pregnancy was performed. In 36 examinations, both real-time and static images were compared, and real-time was judged superior in 22 based on a correlation between the original report and surgical pathology. The appearance of the endometrial canal and the adnexa was characterized in a total of 65 scans. The endometrial canal appearance was variable, with the most common finding being a linear echo (39%). The adnexal changes were less diverse, with an adnexal ring suggestive of an extrauterine gestational sac identified in 60%. In 10 cases, the adnexal ring contained a distinct fetus with a measurable crown-rump length, and cardiac activity was evident in six. Our results indicate that real-time ultrasound coupled with serum beta-hCG RIA should be the procedure of choice when ectopic pregnancy is suspected.
对60例经手术确诊为异位妊娠的患者的超声图进行了分析。在36次检查中，对实时图像和静态图像进行了比较，根据原始报告与手术病理之间的相关性，22次检查判定实时图像更佳。总共65次扫描对子宫内膜管和附件的表现进行了特征描述。子宫内膜管的表现多样，最常见的发现是线状回声（39%）。附件的变化较少样，60%发现有提示宫外妊娠囊的附件环。在10例病例中，附件环内有一个可测量头臀长度的明显胎儿，6例有明显的心搏。我们的结果表明，当怀疑有异位妊娠时，实时超声结合血清β-hCG放射免疫分析应是首选的检查方法。
