| | Chorionic Villus Sampling (CVS) and Amniocentesis at GIVF |
 | | This summary may be most useful for the patient whose reason for consideration of prenatal testing is maternal age greater than 35 years, with no other significant risk factors evident from the family and medical history. | | | This overview summarizes some of the major highlights of genetic risks for women considering amniocentesis or chorionic villus sampling, and also summarizes our assessment of some of the advantages and disadvantages of these alternative diagnostic techniques. | | | The risk of having a child with a neural tube defect (anencephaly or spina bifida, which are major malformations of the brain or spinal cord) averages about 1-2 in 1000. |

| | Chorionic Villus Sampling (CVS) - SJMMC, Ann Arbor, Michigan |
| | You may feel some cramping when the needle is inside your uterus. | | | Therefore, if you have Rh-negative blood, you will be given the Rh immune globulin vaccine (such as RhoGAM) to prevent Rh sensitization which could harm your baby if he or she has Rh-positive blood. | | | Your skin where the needle will be inserted is cleaned with alcohol and numbed with an injection of pain medication (local anesthetic). |

| | Chorionic villus sampling |
| | Women undergoing chorionic villus sampling may experience no pain at all or feel cramping or pinching. | | | Of women who undergo transcervical chorionic villus sampling, one third experience minimal vaginal spotting and 7-10% experience vaginal bleeding. | | | Amniocentesis is usually performed in the second trimester at approximately 16 weeks gestation and the laboratory analysis may take two to three weeks. |

| | Chorionic Villus Sampling (CVS) |
| | Ultrasound is used to locate the chorionic villus and the baby. | | | It also helps guide placement of the tube or needle. | | | This is very dependent upon the experience of the physician performing the procedure but may be slightly higher than the risk with amniocentesis, which is about 1 in 350 cases. |

| | Use of the Portex cannula was more likely to result in an inadequate sample and a difficult or painful procedure when compared with either the silver or aluminium cannula respectively. | | | REVIEWER'S CONCLUSIONS: Although there is some evidence to support the use of small forceps for transcervical chorionic villus sampling, it is not strong enough to support change in practice for clinicians who have become familiar with aspiration cannulas. | | | The incidence of talipes was greater in the early amniocentesis group, although haemangiomas were more common in the chorion villus sampling group. |

| | An ultrasound is used to guide a thin, hollow needle through the abdomen toward the chorionic villus. | | | Guided by ultrasound, the doctor threads a catheter through the vagina and cervix to the chorionic villus, the threads of tissue (villi) that attach the amniotic sac to the uterine wall. | | | If the test is done through the cervix, the vagina and cervix are cleaned with an antiseptic. |

| | Villus - Wikipedia, the free encyclopedia |
| | Villi (singular: villus) are tiny, finger-like structures that protrude from the wall of the intestine and have additional extensions called microvilli (singular: microvillus) which protrude from epithelial cells lining villi. | | | There are also enzymes on the surface for digestion. | | | In all humans, the villi and microvilli together increase intestinal absorptive surface area 30-fold and 600-fold, respectively, providing exceptionally efficient absorption of nutrients in the lumen. |

| | ARS Publication request: Isolation of Enterocytes Along the Crypt-Villus Axis of the Small Intestinein the Neonatal Pig |
| | Technical Abstract: The objective was to isolate enterocytes along the crypt-villus axis from the small intestine in the neonatal pig with the distended sac method. | | | Twelve hours after an intraperitoneal injection of 3H-thymidine (0.5 mCi/kg body weight), four segments (60 cm each) of proximal jejunum were dissected from each of 4 piglets (age 15-16 d) and were flushed with phosphate-buffered saline with 0.2 mM phenylmethylsulfonyl fluoride (PMSF) and 0.5 mM dithiothreitol (DTT). | | | These results suggest that the distended sac method can be used to obtain enriched populations of mature villus and undifferentiated crypt enterocytes from neonatal pigs. |
