| Ectopic pregnancies occur in the fallopian tube
About 97% of ectopic pregnancies occur in the fallopian tube. The remainder implant in the abdominal cavity, on the ovary, or within the cervix. Heterotopic pregnancies occur in one of these areas, while there is also a pregnancy in the uterus. Approximately 100,000 ectopic pregnancies occur each year. Approximately 1 in 66 women will experience this type of pregnancy. Ectopic pregnancy is a very serious condition. When the pregnancy grows in these abnormal areas, it can easily cause massive, rapid bleeding, and even death.
Most ectopic pregnancies occur in the Fallopian tube (so-called tubal pregnancies), but implantation can also occur in the cervix, ovaries, and abdomen. The fetus produces enzymes that allow it to implant in varied types of tissues, and thus an embryo implanted elsewhere than the uterus can cause great tissue damage in its efforts to reach a sufficient supply of blood.
Transvaginal ultrasound
This test can be used during pregnancy. (See also pregnancy ultrasound.) Alternative Names:
Endovaginal ultrasound How the test is performed:
You will be lying down on a table. The transducer is a long probe, covered with a condom and a sterile lubricant, that is inserted into the vagina. The health care provider will then move the probe within the vaginal cavity to scan the pelvic structures. How to prepare for the test:
The examination is done with your bladder empty. Sometimes, a transabdominal ultrasound is done just before a transvaginal ultrasound to look at organs in your abdomen. If so, you may be asked to drink several glasses of water without voiding before the transabdominal exam. Then, you will be asked to empty your bladder after the transabdominal test and before the transvaginal exam.
