Ultrasound in early pregnancy - is it worth doing?
ultrasound early in pregnancy, in its first week, it does not do everything.The first routine ultrasound examination is recommended at 11-13 weeks of pregnancy.This allows you to identify the most serious fetal abnormalities, formed in the period Share of organs and tissues.
Early diagnosis of pregnancy by ultrasound
clearly pregnancy with ultrasound may be determined by the presence of 6-7 weeks heartbeat of the fetus (fetal pulsation).According to some signs of pregnancy can be determined and at 4-5 weeks, but it will not be entirely accurate.
ultrasound in the first month of pregnancy can be done in two ways - transabdominal and transvaginal.When transabdominal method of investigation is carried out through the abdominal wall, and the woman should be prepared before the test - drink plenty of fluids to fill the bladder Urinary bladder - structure and function .A full bladder backs the uterus and makes it easier to consider it.
But in early pregnancy transabdominal ultrasonography may give way to a fuzzy image.Therefore, after examining the woman asks for help and spend transvaginal study using a vaginal probe.The smaller the distance from the sensor to the uterus allows for sharper images, confirm the pregnancy and to set time.
ultrasound in the early weeks of pregnancy - what pathology can be identified?
main pathologies that can be detected in the first weeks - is an ectopic pregnancy Ectopic pregnancy - Fatal dangerous .Thus at time of 6-7 weeks one can see a clear surge fetus, but not in the uterus, and it is, for example, one of the fallopian tubes.And as the developing fetus may break the fallopian tube until the eighth week of pregnancy, a woman has a chance to carry out the planned operation.
Planned surgery for an ectopic pregnancy is nothing like an emergency.When surgery is elective surgery is performed by endoscopic access allows you to remove the fallopian tube of the fertilized egg without injury.Later this fallopian tube maintains patency.
Emergency surgery for an ectopic pregnancy is carried out to break the fallopian tube on the background of severe bleeding and pain.Since the urgent need to stop the bleeding, fallopian tube or a bandage was removed, after which the egg released from the ovary during ovulation Ovulation - How to determine as accurately as possible? on this side, in the conception Conception, ovarian cycle, fertilization and genetics child can not participate.Repeated ectopic pregnancy on the other hand faces a complete infertility.
first routine ultrasound early in pregnancy
first routine ultrasound is recommended at the end of - the beginning of the second trimester of pregnancy on term of 11-13 weeks.At this time, the US has seen the most serious pathology of organs and tissues, formed during their bookmarks.
Particular importance is attached to the study of the identification of congenital malformations - malformations.Timely detection of malformations incompatible with life time to allow a woman to terminate a pregnancy, and then undergo a full examination and may give birth to a healthy baby.Such flagrant anomalies include absence of limbs, heads, abnormal development of the limbs or spinal column, and so on.
less grave anomalies, for example, anomalies of the internal organs, the first ultrasound, you can not see because of the small size of the organs.These anomalies will be revealed later in the second ultrasound, which is held at 21-24 weeks of gestation.
The first ultrasound can also by certain characteristics (markers) to identify some chromosomal disorders such as Down syndrome.
is also important early detection of multiple pregnancies.All multiple pregnancies (twins, triplets, etc.) often occur with complications.The doctor and the woman should know about it.
Is it worth doing ultrasound early in pregnancy
ultrasound in early pregnancy do to confirm the pregnancy and to rule out an ectopic pregnancy in the presence of this evidence.That is, if there are doubts about the presence of pregnancy (questionable laboratory tests), or a woman has previously had an ectopic pregnancy.
first routine ultrasound, which is carried out in 11-13 weeks, is mandatory for all pregnant women.It is a screening that is, reveals among all pregnant women a certain pathology.Ignore this study is extremely dangerous: too great a risk to give birth to a sick child.
ultrasound in early pregnancy not only allows accurate diagnosis of pregnancy and its term, but also to identify the major defects of the fetus, fetal chromosomal disease that is the most serious pathology.
