For excessive fluid: The surgeon or cardiologist may do this with local or additional anesthesia depending on the issue. Fluoroscopy, ultrasound, or ct can be used to help guide the needle and / or/ catheter introduction through the skin, soft tissue, pericardium to get to the fluid or blood identified on the original test-echo. The goal is to relieve tamponade and make a diagnosis. ...Read moreSee 1 more doctor answer
What are amniocentesis, chorionic villus sampling and blood/saliva test screening used for? Abortions?
Prenatal diagnosis: Cvs and amniocentesis are used to discover chromosomal abnormalities in the fetus. They are also used to diagnose genetic diseases, such as cystic fibrosis, that some people are at risk for. Blood and saliva screening tests are used to find out if parents are at risk for a baby with certain genetic diseases. ...Read moreSee 1 more doctor answer
Computerized locati: The suspicious density, seen in x-ray but can not be felt , this area is located in two or more planes, marked, computer guided needle enters, at the marked site and takes biopsy, radio opaque, marker is placed for future reference, that biopsy was taken from correct location , then simple small dressing will be applied. ...Read more
See below: Thoracentesis is when fluid is removed from the space between your lung and the chest wall with a needle - usually done to relieve pressure, or send a culture. Bronchoscopy is done to look inside your airways with a camera (bronchoscope). It is done for numerous reasons: clean up secretions, look at anatomy, investigate tumors, obtain biopsies, and others. ...Read more
10-12 weeks: Chorionic villus sampling (cvs) obtains cells from the fetoplacenta for testing at 10-12 weeks of pregnancy, amniocentesis obtains fetal skin/urine cells at 16-18 weeks. Higher risks for miscarriage (2-3% for cvs, <0.5% or negligible for amnio) balance against the cvs advantage of testing before a women "shows, " preserving the privacy of pregnancy (testing). ...Read more
See answer: Thoracocentesis is the procedure where a needle is used to “draw off / sample” fluid from the chest pleural space – for either diagnostic (fluid sent for cytology, culture, etc.) or therapeutic purposes (too much fluid causing compression). Ct biopsy is the procedure where a needle actually biopsies a specific organ to evaluate the target tissue. ...Read more
Needling procedure.: Amnioparacentesis in greek (amnio for short) is a prenatal invasive diagnostic genetic procedure devised to glean information from the pregnancy sac with small risk. It is used to determine fetal dna make-up, mutations, anemia, infections, open neural tube or abdominal wall defects. It is typically done 16-22 weeks by maternal-fetal or genetic specialists; complications occur in 1:100-1:1, 000. ...Read more
With a needle.: A needle is introduced into the chest and through the pericardium ( the sac around the heart) into the pericardial space (between the pericardium and the heart) where excess fluid has accumulated. A flexible wire is advanced through the needle into the pericardial space and the needle is withdrawn. A flexible drain tube is advanced over the wire and the wire removed. The fluid is then drained. ...Read moreSee 1 more doctor answer
Genetic testing: Chorionic villous sampling represents one of the earliest available methods to accurately diagnose genetic abnormalities such as down's syndrome. While most, if not all, of these defects are not curable, it does give the patient the earliest opportunity to decide on whether to continue the pregnancy. ...Read more
That : That is true. Some pregnant patients have "polyhydramnios", where there is too much fluid around the baby, which can occur for several reasons. In that case, extra fluid can be drained. The most common indication for amniocentesis is for diagnostic purposes, where fluid is tested to determine the health and genetics of the baby. ...Read more
Safety of chorionic sampling vs. Amniocentesis for prenatal diagnosis of chromosomal abnormalities?
Risks: The risk of pregnancy loss has been looked at in four randomized studies of cvs vs. Amniocentesis. All four studies show that both procedures have about the same risk of pregnancy loss. About 1 in 1600. Another cvs study showed that losses in a group of women who had the procedure were equal to losses in a group of women who didn't have the procedure. A loss may not be related to the procedure. ...Read more
MFMs: Maternal fetal medicine specialists usually perform cvs, although there are occasional doctors of other specialties who have been trained to do the procedure. Fellows, who are still in training, may perform the procedure under the supervision of the doctor who is teaching them. ...Read more
