The following types of attachment of the ovum in the ectopic pregnancy ( types of ectopic pregnancy ):
- abdominal (abdominal) pregnancy - 0.3% of cases;
- ovarian pregnancy - 0.2%;
- tubal pregnancy (ampullar, isthmic and interstitial) - 98.69%, of which 3% are cases of interstitial pregnancy;
- cervical pregnancy - 0.01%;
- fertilized egg in the body of the uterus - 0.25%;
- fertilized egg in the uterine rudimentary horn - 0.25%;
- intrauterine and ectopic pregnancy at the same time - 0.1% of cases.
most common form of ectopic pregnancy - this is the wrong attachment of a fertilized egg, which occurs in the fallopian tube, usually in the right.
Pregnancy , in which the embryo develops in the fallopian tube (tubal pregnancy), divided into isthmic, ampullar and interstitial.In most cases, the egg is in the region of the fallopian tube vials, resulting in very serious consequences.Fertilized egg to attach to the narrower parts of the fallopian tube (ist
pregnancy in which the embryo develops into a wider portion (in the oviduct ampoule or final parts - funnel) can remain undetected for longer, about 8 to 12 weeks.It is manifested by long mild pain and significant bleeding into the abdominal cavity.Fertilized egg, placed in such a way can be expelled from the oviduct through his abdominal end (so-called tubal abortion) in the abdominal cavity, where the dies or is attached to the ovary or peritoneum.
Ovarian pregnancy , when the fertilized egg to implant in the ovary, may have a primary character as a result of delays in the ovary and the egg fertilization in this place, or secondary - due to the re-implantation of the ovum after tubal abortion.Ovarian tissue, richly covered with blood vessels, very quickly collapse, and there is bleeding into the abdominal cavity.
Cervical pregnancy - it's quite a rare event, but it is especially dangerous to a woman's life due to the fact that this region has a dense network of blood vessels.In this case the attachment occurs in the uterine cavity, but in its lower part - in the neck.This arrangement contribute to the operation carried out on the uterus, it malformations and benign tumors, as well as numerous miscarriages.The small space of the cervical canal interferes with the normal development of the pregnancy.If the growing fertilized egg will not be moved into the vagina for a fairly short period of time is the destruction of the blood vessels, which leads to excessive bleeding from the birth canal.
abdominal (abdominal) pregnancy can be a primary, but more often is the result of re-attachment of the ovum after tubal abortion.Fertilized egg can be implanted in any of the abdomen, often in the intestines or peritoneum.This rare form of ectopic pregnancy also poses a threat to the mother's life, threatening her bleeding and infection.Most of the fruit developing in the abdominal cavity die.However, there are cases where they survived, but it had severe malformations.Naturally, labor may then only be carried out promptly, i.e.by caesarean section.
pregnancy in which the fertilized egg in the uterine wall is located, is an extremely rare form of ectopic pregnancy, the essence of which is too deeply rooted deep trophoblast uterine wall.This phenomenon contribute any scars left after surgery on the uterus or its weakening due to illness.There is a rupture of the uterus and expulsion of the fetus in the abdomen, where it can be re-attached.
Pregnancy in rudimentary horn of the uterus - is a type of ectopic pregnancy is similar to that described above, except that the implantation occurs in the uterine horn.
Pretty rare appearance another ectopic pregnancy - both developing intrauterine and ectopic pregnancy, one of the eggs fertilized simultaneously attached properly to the uterine cavity, and the other - outside the cavity.
