Ectopic Pregnancy
异位妊娠
Normally a fertilized egg implants in the uterus. But if the fertilized egg implants somewhere, other than the uterus, the pregnancy is said to be ectopic which means located in an abnormal position.
正常情况下，受精卵将植入子宫。但是，如果受精卵植入子宫以外的其他部位，则称为异位妊娠，即受精卵植入异常部位。
When an ectopic pregnancy occurs, the fertilized egg usually implants in one of the fallopian tubes.
异位妊娠通常发生于输卵管，即受精卵在任一侧输卵管着床。
Because the fallopian tube is narrow and its walls are thin, the pregnancy only has to be about the size of a jellybean before the fallopian tube bursts causing major bleeding.
由于输卵管很狭窄，壁很薄，所以包块仅约跳跳糖大小，就会造成输卵破裂，导致大出血。
Occasionally, the fertilized egg may implant on an ovary, in the abdominal cavity, or in the cervix.
有时，受精卵可能在卵巢、腹腔或宫颈内着床。
Ectopic pregnancies are rare, they occur in about one out of every 60 pregnancies.
异位妊娠相当罕见，发生率约为 1/60。
There are certain risk factors that make an ectopic pregnancy more likely.
某些危险因素更可能导致异位妊娠。
These risks include a history of pelvic inflammatory disease or PID, sexually transmitted diseases such as chlamydia, or gonorrhea, a previous ectopic pregnancy, or a previous tubal surgery for infertility.
这些因素包括盆腔炎（PID）病史、衣原体感染或淋病等性传播疾病、既往异位妊娠，或者既往不孕症输卵管手术史。
Treatment of an ectopic pregnancy either medically or surgically is necessary to prevent serious even life-threatening complications.
我们必须通过药物或手术治疗异位妊娠，防止发生严重，甚至危及生命的并发症。
