Abstract：
Ectopic pregnancies are one of the most common causes of obstetric mortality worldwide. Interstitial ectopic pregnancies, defined as an extracavitary pregnancy within the portion of the Fallopian tube that transverses the myometrium, have reported mortality rates approximately seven times higher than all types of ectopic pregnancy combined. In contrast, intracavitary eccentric gestations, often labeled as \"cornual\" or \"angular\" pregnancies, have reportedly high rates of live birth. Unfortunately, the terms \"interstitial,\" \"cornual,\" and \"angular\" have long been used with varying diagnostic criteria and often interchangeably to describe a pregnancy near the uterotubal junction. The inconsistency in nomenclature and lack of clear diagnostic criteria to distinguish among these pregnancies has resulted in a paucity of data to provide accurate prognostic information and guide appropriate management. This review article aims to provide historical context for the terms \"interstitial,\" \"cornual,\" and \"angular;\" discuss previous and more recent innovations of diagnostic methods; and provide recommendations for concise terminology and inform management.
摘要：
异位妊娠是全球产科死亡的最常见原因之一。间质性异位妊娠,定义为穿过子宫肌层的输卵管部分内的腔外妊娠，报告的死亡率比所有类型的异位妊娠合并高约7倍。相比之下,腔内偏心妊娠，通常被标记为“角型”或“角型”怀孕，据报道，活产率很高。不幸的是,术语“间质性”，\"\"cornual,\"和\"角度\"长期以来一直被用于不同的诊断标准，并且经常互换地描述子宫输卵管交界处附近的妊娠。术语的不一致和缺乏明确的诊断标准来区分这些怀孕，导致缺乏数据来提供准确的预后信息并指导适当的管理。这篇综述文章旨在为术语“插播，\"\"cornual,\"and\"angular;\"discusspreviousandmorerecentinnovationsofdiagnosticmethods;andproviderecommendationsforconficioustermsandinformmanagement.
