Ultrasound-Based Diagnosis of Interstitial Ectopic Pregnancy: Role of Morphological Features.
This was a retrospective observational study utilizing data from a single-specialist early-pregnancy unit. We evaluated the diagnostic accuracy of transvaginal ultrasound (TVS) in various morphological presentations of interstitial ectopic pregnancy (IEP) among women who underwent surgery. Based on the presence or absence of a gestational sac (GS), IEP morphology was classified as GS type or inhomogeneous solid (IS) type. During the study period, 27 patients with IEP underwent surgical intervention. In those with the GS type, we observed a strong correlation between preoperative ultrasonographic findings and surgical observations; the positive predictive value of TVS diagnosis for GS-type IEP was 100%. In contrast, it was 45.5% for IS-type IEP, which presents unique diagnostic challenges due to its complex ultrasonographic appearance. Additionally, we assessed the ultrasound characteristics of IS-type IEP and discussed its differential diagnosis.
期刊介绍：
The Journal of Clinical Ultrasound (JCU) is an international journal dedicated to the worldwide dissemination of scientific information on diagnostic and therapeutic applications of medical sonography.
The scope of the journal includes--but is not limited to--the following areas: sonography of the gastrointestinal tract, genitourinary tract, vascular system, nervous system, head and neck, chest, breast, musculoskeletal system, and other superficial structures; Doppler applications; obstetric and pediatric applications; and interventional sonography. Studies comparing sonography with other imaging modalities are encouraged, as are studies evaluating the economic impact of sonography. Also within the journal''s scope are innovations and improvements in instrumentation and examination techniques and the use of contrast agents.
JCU publishes original research articles, case reports, pictorial essays, technical notes, and letters to the editor. The journal is also dedicated to being an educational resource for its readers, through the publication of review articles and various scientific contributions from members of the editorial board and other world-renowned experts in sonography.
