腹腔妊娠是指位于输卵管、卵巢、阔韧带以外的腹腔内妊娠,是一罕见而危险的产科并发症。其发生率约为1:15(?)次分娩,对母婴的生命威胁极大。据报道,母婴死亡率分别为10～20%及40～80%。如能及时作出诊断进行正确处理。可大大降低母婴死亡率。病因:腹腔妊娠多为继发性,原发性者罕见。继发性者可来源于三个方面:①子宫方面。因子宫有缺损(疤痕愈合欠佳)、憇室(自然破裂)或宫壁发育欠佳致破裂等,以及子宫腹膜瘘等。②卵巢妊娠破裂;③输卵管妊娠流产破裂,孕卵落入腹腔在某一部位种植、着床、妊娠继续而至腹腔妊娠。原发性腹腔妊娠的原因,有人认为可能是排卵后,卵子和游离于腹腔内精子结合受精,而后种植在腹腔的的某一部位,并在此生长发育。
Abdominal pregnancy is located in the fallopian tube, ovary, broad ligament beyond the abdominal pregnancy, is a rare and dangerous obstetric complications. The incidence of about 1:15 (?) Delivery, the great threat to the lives of mothers and babies. According to reports, maternal and infant mortality rates were 10 to 20% and 40 to 80%. If timely diagnosis can be done correctly. Can greatly reduce maternal and infant mortality. Etiology: mostly intraperitoneal pregnancy secondary, rare primary. Secondary can be derived from three aspects: ① uterine aspects. Due to uterine defects (scar healing poor), cholera room (natural rupture) or rupture of the palace wall poor growth, as well as uterine peritoneal fistula. ② ovarian rupture of pregnancy; ③ tubal abortion rupture of pregnancy, pregnancy eggs into the abdominal cavity in a certain part of the plant, implantation, pregnancy continue to abdominal pregnancy. The reason of primary intraperitoneal pregnancy, some people think may be ovulation, ovum and free intraperitoneal sperm combined with fertilization, and then planted in a certain part of the abdominal cavity, and in this growth and development.
