What is a Tubal Pregnancy? A Tubal pregnancy occurs when implantation
occurs outside the womb. Implantation can occur in the ovary, the abdomen, the
cervix, at the join between the tube and the womb, but the most common place is
in the fallopian tube. Pregnancy can even occur in both the womb and the tube
at the same time (heterotopic pregnancy), but this is very rare.
How common is it? The percentage of pregnancies which are Tubal is
between 0.25 and 1%
What causes a Tubal Pregnancy? A Tubal pregnancy is usually caused
by conditions which slows down or obstructs the movement of the egg down the fallopian
tube into the uterus. Any condition which may have damaged the fallopian tubes
increases the risk of a Tubal pregnancy. The possible causes of Tubal pregnancies
include: · Pelvic inflammatory disease - an infection of the female
reproductive organs which can cause scarring of the organs. · A history
of Endometriosis - a disease where tissue usually found in the uterus develops
in other areas of the body. · Previous tubal surgery ·
Multiple induced abortions · Pelvic adhesions - bands of scar tissue
that constrict the tube
What are the Tubal Pregnancy symptoms? The most common symptoms of
Tubal pregnancy or signs of Tubal pregnancy include: · Sharp pain
in the abdomen or pelvis · Signs of early pregnancy ·
Vaginal bleeding · Tender abdomen · Diziness or fainting
and generally not feeling well Always consult your physician for a diagnosis
if you experience any of the symptoms of a Tubal pregnancy.
How is a Tubal Pregnancy diagnosed? The diagnosis of a Tubal pregnancy
can be difficult. Your doctor may perform some tests to help confirm s suspected
Tubal pregnancy. These tests include: · Pelvic exam ·
Blood tests · Ultrasound · Culdocentesis - determines
if there is blood in the space behind the uterus · Laparoscopy - a
telescope is inserted through a small incision in the woman's abdomen. This allows
the doctor to see the fallopian tubes and other organs. This takes place in an
operating room with anesthesia.
How is a Tubal Pregnancy treated? If a Tubal pregnancy is strongly
suspected, then a gynaecologist will perform a laparoscopy to confirm it. During
a laparoscopy, the fallopian tube is often removed at the same time. Sometimes
open surgery is required to remove the pregnancy. Methotrexate can be
used as a chemical treatment. It is used in non-urgent cases to dissolve the pregnancy
without harming the tubes and other organs. Repeat hCG levels will be taken to
ensure that the pregnancy is dissolving and that further treatment is not needed.
The outlook for future pregnancies depends on whether the fallopian
tube appeared normal or not. Generally 1 in 5 women who experienced a Tubal pregnancy
will experience another Tubal pregnancy.
An Ectopic Pregnancy occurs when the fertilized egg attaches itself in a place
other than inside the uterus. Almost all ectopic pregnancies occur in a fallopian
tube, and are thus sometimes called tubal pregnancies. The fallopian tubes are
not designed to hold a growing embryo; the fertilized egg in a tubal pregnancy
cannot develop normally and must be treated. An ectopic pregnancy happens in 1
out of 60 pregnancies. What causes an ectopic pregnancy? Ectopic
pregnancies are caused by one or more of the following: · An infection
or inflammation of the fallopian tube can cause it to become partially or entirely
blocked. · Scar tissue left behind from a previous infection or an
operation on the tube may also impede the egg's movement. · Previous
surgery in the pelvic area or on the tubes can cause adhesions. ·
An abnormality in the tube's shape can be caused by abnormal growths or a birth
defect. Who is at risk for having an ectopic pregnancy?
Women who are more at risk for having an ectopic pregnancy include the following:
· Are 35-44 years of age · Have had a previous ectopic pregnancy
· Have had pelvic or abdominal surgery · Have Pelvic Inflammatory
Disease (PID) · Have had several induced abortions · Women
who get pregnant after having a tubal ligation or while an IUD is in place
What are the symptoms of an ectopic pregnancy? The following symptoms
may be used to help recognize a potential ectopic pregnancy: · Sharp
or stabbing pain that may come and go and vary in intensity. The pain may be in
the pelvis, abdomen or even the shoulder and neck (due to blood from a ruptured
ectopic pregnancy gathering up under the diaphragm). · Vaginal bleeding,
heavier or lighter than your normal period · Gastrointestinal symptoms
· Weakness, dizziness, or fainting It is important for you
to seek emergency care if you are experiencing sharp pain or have bleeding.
How is an ectopic pregnancy diagnosed? Ectopic pregnancies are
diagnosed by your physician who will probably first perform a pelvic exam to locate
pain, tenderness or a mass in the abdomen. Your physician will also use an ultrasound
to determine whether the uterus contains a developing fetus. The measurement
of hCG levels is also important. An hCG level that is lower than what would be
expected is one reason to suspect an ectopic pregnancy. Low levels of progesterone
may also indicate that a pregnancy is abnormal. Your physician may do
a Culdocentesis, which is a procedure that involves inserting a needle into the
space at the very top of the vagina, behind the uterus and in front of the rectum.
The presence of blood in this area may indicate bleeding from a ruptured fallopian
tube. How is an ectopic pregnancy treated? An ectopic pregnancy
may be treated in any of the following ways: · Methotrexate may be
given, which allows the body to absorb the pregnancy tissue and may save the fallopian
tube, depending on how far the pregnancy has developed. · If the tube
has become stretched or it has ruptured and started bleeding, all or part of the
fallopian tube may have to be removed. Bleeding needs to be stopped promptly,
and emergency surgery is needed. · Laparoscopic surgery under general
anesthesia may be performed. This procedure involves a surgeon using a laparoscope
to remove the ectopic pregnancy and repair or remove the affected fallopian tube.
If the ectopic cannot be removed by a laparoscope procedure, then another surgical
procedure called a laparotomy may be done. What about my future?
Your hCG level will need to be rechecked on a regular basis until it reaches zero
if you did not have your entire fallopian tube removed. An hCG level that remains
high could indicate that the ectopic tissue was not entirely removed, which would
require surgery or medical management with methotrexate. The chances
of having a successful pregnancy after an ectopic pregnancy may be lower than
normal, but this will depend on why the pregnancy was ectopic and your medical
history. If the fallopian tubes have been left in place, you have approximately
a 60% chance of having a successful pregnancy in the future.
