早期的宫颈妊娠被当作宫腔妊娠流产行刮宫术时,由于宫颈组织的破坏程度很浅,胚胎组织可能被搔刮掉而将宫颈妊娠的诊断遗漏。此种情况下的确诊有赖于病理检查。有肿瘤的病史、症状及检查所见。此类肿瘤一般无早期妊娠征象,滋养细胞肿瘤有高HCG检查值但无早孕期的动态变化;葡萄胎有水泡样组织排出史。B超检查在子宫颈管内看不到胚胎组织,在宫腔内有典型的水泡影像;细胞学检查及活体组织检查均有助于确诊。宫颈妊娠首先应与宫内妊娠流产鉴别。后者子宫体增大而宫颈不大;阴道出血常伴有阵发性腹痛;宫颈内口开大,胚胎组织排出后,促进子宫收缩多可止血;若胚胎组织嵌于宫口,可以手取或钳取除去,不似宫颈妊娠时胚胎组织与颈管紧密连接;仔细检查,可发现宫颈内口仍然闭合。如果妊娠早期人工流产扩张宫颈时有特殊疼痛,或刮宫时有不 Early cervical pregnancy is treated as a uterine decidua curettage, due to the destruction of cervical tissue is very shallow, embryonic tissue may be scraped off and the diagnosis of cervical pregnancy missing. Diagnosis in this case depends on the pathological examination. Have a history of cancer, symptoms and inspection seen. Such tumors generally have no signs of early pregnancy, trophoblastic tumors have high HCG test values ​​but no dynamic changes during the first trimester; hydatidiform mole tissue discharge history. B-ultrasound in the cervix can not see the embryonic tissue in the uterine cavity with a typical blister image; cytology and biopsy are helpful to confirm the diagnosis. Cervical pregnancy should first identification of intrauterine pregnancy and abortion. The latter increases the uterus and the cervix is ​​not; vaginal bleeding is often accompanied by paroxysmal abdominal pain; cervix opened mouth large, embryonic tissue discharge, to promote uterine contractions and more to stop bleeding; embryo tissue embedded in the cervix, you can hand or Forceps removed, not like cervical pregnancy embryo tissue tightly connected with the neck tube; a careful examination, you can find the mouth of the cervix is ​​still closed. If the first trimester of pregnancy induced abortion cervical special pain, or curettage when not
