Abstract:

Although interstitial pregnancy accounts for a small part of ectopic pregnancy，it can be life-threating once ruptured.The high risk factors include tubal pathology，pelvic inflammatory diseases or a history of it，and histories of ectopic pregnancy or tubal surgeries.The preoperative diagnosis of interstitial pregnancy mainly depends on ultrasound or MRI，with laparoscopic and hysteroscopic examination being the most direct and decisive diagnosis.Except in a limited number of cases，laparoscopic surgery is currently the choice of treatment with either cornuectomy or cornuostomy.

Key words: ectopic pregnancy, interstitial pregnancy, high risk factors, cornuectomy

摘要：

输卵管间质部妊娠在异位妊娠中所占比例较小，但一旦破裂，可出现致命性大出血。其发病高危因素有输卵管病变、盆腔炎性疾病、盆腔炎性疾病病史、异位妊娠史、输卵管手术史等。输卵管间质部妊娠的术前诊断主要依靠超声检查或MRI，宫腔镜和腹腔镜是诊断输卵管间质部妊娠的最直接和最可靠的方法。除少数病例适合药物治疗外，腹腔镜手术是输卵管间质部妊娠治疗的主要方法，常用的有宫角切除及缝合术（宫角楔形切除术）和宫角切开及缝合术两种术式。
