Fetal ultrasound showed enlarged renal pelvis and large head. So could it be a syndrome?

Fetal ultrasound showed enlarged renal pelvis and large head. So could it be a syndrome?

May or may not.: Enlarged renal pelvises are common urinary tract anomalies. A large head can be familial. So not likely. But then there is much ultrasound can't diagnose. Just have to wait and see. ...Read more

Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

Why do they measure the MCA in maternal fetal ultrasound?

Why do they measure the MCA in maternal fetal ultrasound?

Problem with baby: Blood flow in the MCA (middle cerebral artery) may be abnormal if a baby is not getting enough oxygen, either because it has anemia so that it's blood cannot carry enough oxygen, or because it is not getting enough oxygen from the placenta. If your baby is not growing well, or if you have an infection or problem that might be causing anemia, your doctor may look at the baby's MCA with ultrasound. ...Read more

Since tof is congenital, why doesn't fetal ultrasound always find it?

Since tof is congenital, why doesn't fetal ultrasound always find it?

Heart defects: Tetralogy of fallot, a heart defect, can be difficult to diagnose prenatally. The heart is very small in a developing baby, and specific images must be obtained to make that diagnosis. If the baby is in a bad position, or the mother is obese, or the doctor doesn't have a lot of experience diagnosing heart defects in a fetus, tof can be missed. ...Read more

What is the definition or description of: fetal ultrasound?

What is the definition or description of: fetal ultrasound?

Safe fetal imaging.: Fetal ultrasound is an amazing and safe imaging method employing the piezoelectric properties of quartz crystals to convert electrical current to mechanical vibrations; this creates ultra-high frequency sound waves that can penetrate inside the pregnant woman's body and bounce off different structures with variable characteristics. A computer then processes the feedback signal to image the fetus! ...Read more

Some say that 12wk fetal ultrasound measurements can be off by 2wks, but some say only +\-5 days. Which is it?

Some say that 12wk fetal ultrasound measurements can be off by 2wks, but some say only +\-5 days. Which is it?

Fetal Ultrasound Err: The usual figure cited is +|- two weeks for us performed after 12 weeks: http://www. Newbirthcompany. Com/estimated-due-dates/. There are better measurements (such as fetal crown-rump length) that are more accurate as the weeks go by. Don't worry - your obstetrician will be able to "nail down" a more accurate due date in the weeks ahead! ...Read more

What could a small head on fetal ultrasound be a sign of?

What could a small head on fetal ultrasound be a sign of?

Wrong dates!: The most common reason for suspected fetal microcephaly is erroneous due date assignment. If microcephaly is real, it could be part of several fetal syndromes with poor neurodevopmental outcome, such as aneuploidies (down), perinatal infections (toxoplasmosis, rubella, cmv), or metabolic disorders. ...Read more

When you look at a fetal ultrasound it has two dates on it one is the ga (gestational age) an the other ma is what? Would really like to know thanks

When you look at a fetal ultrasound it has two dates on it one is the ga (gestational age) an the other ma is what? Would really like to know thanks

Maternal age: Gestational age is based on ultrasound measurements of the head, abdomen and femur. Maternal age is based on your last menstrual period. These two ages should be within 10-12 days of each other during the 2nd trimester screening ultrasound. ...Read more

22 wk fetal ultrasound completely normal. The doc remarked a tiny thickening of bladder wall. Fluid fine, kidneys and bladder normal. Should I worry?

22 wk fetal ultrasound completely normal. The doc remarked a tiny thickening of bladder wall. Fluid fine, kidneys and bladder normal. Should I worry?

No Worries: This is an incidental finding, doesn't really mean anything. If your doctor is concerned about it he will follow it with serial ultrasounds. You have enough to worry about being pregnant having diabetes and dealing with life's ever changing challenges. Congratulations on your upcoming child! ...Read more

What are some of the signs and ultrasound findings of down syndrome?

What are some of the signs and ultrasound findings of down syndrome?

Very skilled US: 1st trimester: nuchal translucency wider than normal. Non-Visualization of the nasal bone is sufficient to warrant diagnostic testing. 2nd trimester: most important are cystic hygroma or increased nuchal thickness; dilated ventricles of the brain, absent or small nasal bone, anomalous right subclavian artery. Heart defects, particularly conotruncal, short femur or humerus, duodenal atresia ...Read more

How could Down syndrome be missed on targeted ultrasound in a 40 year old?

How could Down syndrome be missed on targeted ultrasound in a 40 year old?

Screening vs confirm: By definition a screening test is done to more individuals to select the group at higher risk for a problem that justifies a greater cost definitive test. All screening tests can be falsely negative or positive. The definitive tests for DS require chromosome analysis. This can be done in limited centers by finding fetal cells in mothers blood, or by CVS or amniocentesis. ...Read more

What can I do if my doctor didn't find any Down syndrome markers in the ultrasound. Am I out of the woods?

Not necessarily: The definitive test for down or other chromosomal defects is a chromosome study on fetal cells obtained through cvs or amniocentesis. These are specific and dependable. Ultrasounds and blood tests are screening tools. They are helpful in picking out some who might need the definitive tests. At 39 you have about 1% risk for ds but another 4% risk of some other issue (premi, clefts etc.). ...Read more

What do you suggest if my doctor didn't find any Down syndrome markers in the ultrasound. Am I out of the woods?

What do you suggest if my doctor didn't find any Down syndrome markers in the ultrasound. Am I out of the woods?

Maybe: When looking for DS there are a variety of tests used for screening. An ultrasound looks for features that are commonly found in DS, but are not 100% accurate. Tests that look at the babies chromosome pattern by obtaining fetal cells are the most accurate. When someone is in the low risk category, a negative US is probably adequate. If in a higher risk, a more specific test is advised. ...Read more

What does it mean if there are soft markers for Down syndrome on ultrasound?

Fetal ultrasounds in: The 1st & 2nd trimesters can show anatomical signs frequently seen in fetuses with Down Syndrome or other genetic accidents that result in 3 copies of a specific chromosome. Knowing your risk of DS, calculated by FUS findings, gestational & maternal age, 1st & 2nd trimester maternal blood screens, & a higher-resolution FUS, helps you decide if you want chromosomal testing for a definitive answer. ...Read more

My doctor didn't find any Down syndrome markers in the ultrasound. Does that guarantee my baby won't have down syndrome?

No. OB's combine the: Results of an integrated screening test that includes specific blood tests in both the first & 2nd trimesters + the first trimester ultrasound to determine a single Down Syndrome risk rating. Only prenatal diagnostic tests of fetal genetic material for either Karyotype to determine # of chromosomes or Chromosomal Microarray to determine mutations in smaller gene sequences are definitive. ...Read more

I want to known any screening exam to rule out Down syndrome? When is the best to check it? Or only 4D ultrasound can help?

Depends: On what gestational age the fetus is at. The quad screen can predict risk of Downs Syndrome in conjunction with ultrasounds. Needs to be done between the 15th and 20th week of pregnancy. ...Read more
