Chorionic villus sampling
Chorionic villus sampling (CVS) is a prenatal diagnostic procedure that samples placental tissue under ultrasound guidance, usually at 10 to 13 weeks, to detect chromosomal and genetic abnormalities.
Cordocentesis
Cordocentesis, also called percutaneous umbilical blood sampling (PUBS), is a prenatal procedure in which a needle guided by ultrasound withdraws fetal blood from the umbilical cord vein.
Culdoscopes
Culdoscopes are endoscopic instruments passed through the vaginal wall into the rectovaginal pouch to view the pelvic viscera. Devised by Albert Decker, they dominated US gynecological endoscopy circa 1950-1970 before laparoscopy displaced culdoscopy.
Culdoscopy
Culdoscopy, also called transvaginal endoscopy, is a gynecologic procedure in which a culdoscope is inserted through the posterior vaginal fornix into the pouch of Douglas. Developed by Albert Decker in the 1940s, it dominated US gynecologic endoscopy circa 1950-1970 before laparoscopy supplanted it.
Embryo biopsy
Embryo biopsy is a laboratory procedure in assisted reproduction in which cells are removed from an oocyte, zygote, or embryo for genetic testing before transfer.
Endometrial biopsy
Endometrial biopsy is an office-based procedure that removes a small sample of the uterine lining for microscopic diagnosis, chiefly to evaluate abnormal bleeding and detect hyperplasia or cancer.
Fetoscopes
Fetoscopes (also amnioscopes, embryoscopes) are endoscopes for viewing the embryo, fetus, and amniotic cavity. Used since 1967 for diagnosis, revived in the 1990s for fetoscopic laser surgery of twin-to-twin transfusion syndrome and fetal tracheal occlusion.
Fetoscopy
Fetoscopy is a minimally invasive prenatal procedure in which a fiber-optic endoscope inserted through the mother's abdomen views and treats the fetus, chiefly for twin-to-twin transfusion syndrome.
Gynecologic laparoscopy
Gynecologic laparoscopy is a minimally invasive surgical technique in which a laparoscope and instruments are inserted through small abdominal incisions to diagnose and treat conditions of the female reproductive organs.
Hysteroscopes
A hysteroscope is a thin, telescope-like instrument inserted through the vagina and cervix to view the inside of the uterus, diagnose abnormal bleeding, and remove polyps, fibroids, or adhesions.
Hysteroscopic resection
Hysteroscopic resection is a minimally invasive gynecological operation in which a hysteroscope views the uterine cavity and cuts away lesions such as polyps, submucosal fibroids, and uterine septa.
Invasive prenatal testing
Invasive prenatal testing is the set of procedures, chiefly chorionic villus sampling (CVS) and amniocentesis, that sample fetal cells for definitive diagnosis of chromosomal conditions.
Office hysteroscopy
Office hysteroscopy is an outpatient gynecological procedure in which a thin hysteroscope is inserted through the cervix to diagnose and treat intrauterine abnormalities in one visit.
Operative hysteroscopy
Operative hysteroscopy is a minimally invasive gynecological procedure in which a hysteroscope passed through the cervix diagnoses and surgically treats intrauterine disease, including polyps, fibroids, septa, and adhesions.
Trophectoderm biopsy
Trophectoderm biopsy is an IVF micromanipulation procedure that removes 5 to 10 cells from a blastocyst's outer layer, days 5 to 7 after insemination, for preimplantation genetic testing.
Vaginoscopy
Vaginoscopy is the insertion of an endoscope into the vagina without a speculum or other instrumentation, distending the vagina with saline to visualize the vaginal walls and cervix.
