Heterotopic pregnancy is the occurrence of simultaneous intrauterine and extrauterine pregnancies. Heterotopic pregnancy most commonly occurs during the first trimester of pregnancy in women who have significant risk factors including assisted reproductive therapy, prior ectopic pregnancy, and prior pelvic surgery or pelvic inflammatory disease. Although rare, heterotopic pregnancy must be recognized using ultrasound so as to provide appropriate treatment to the extrauterine pregnancy with the goal of preserving the intrauterine pregnancy. The case presented describes a patient with a pathologically proven (figure 8A and 8B), surgically treated 1st trimester heterotopic pregnancy.
异位妊娠是指同时发生宫内妊娠和宫外妊娠。异位妊娠最常发生在妊娠早期，多见于有重大危险因素的女性，包括辅助生殖治疗、既往异位妊娠史、既往盆腔手术史或盆腔炎病史。尽管罕见，但必须通过超声识别异位妊娠，以便对宫外妊娠进行适当治疗，目标是保留宫内妊娠。本文介绍的病例是一名经病理证实（图8A和8B）、接受手术治疗的妊娠早期异位妊娠患者。
