Asherman's syndrome (AS) is an acquired uterine condition that occurs when scar tissue forms inside the uterus and/or the cervix. [1] It is characterized by variable scarring inside the uterine cavity, where in many cases the front and back walls of the uterus stick to one another.
On ultrasound, a normal placenta should appear complete and uniform, with the fetal surface of the placenta appearing slightly shiny and translucent. The appearance of a circumvallate placenta on ultrasound may present with irregular edges, uplifted margins, or placental sheets.
The anomaly scan, also sometimes called the anatomy scan, 20-week ultrasound, or level 2 ultrasound, evaluates anatomic structures of the fetus, placenta, and maternal pelvic organs. This scan is an important and common component of routine prenatal care . [ 1 ]
Device for both vaginal ultrasonography and abdominal ultrasonography Transvaginal ultrasonography to check the location of an intrauterine device (IUD). The examination can be performed by transabdominal ultrasonography, generally with a full bladder which acts as an acoustic window to achieve better visualization of pelvis organs, or by transvaginal ultrasonography with a specifically ...
667 Retained placenta or membranes, without hemorrhage; 668 Complication (medicine) of the administration of anesthetic or other sedation in labor (childbirth) and delivery; 669 Complication (medicine) Other complications of labor and delivery, not elsewhere classified. 669.5 Forceps delivery or vacuum extractor delivery without mention of ...
Somatic errors are thus less likely than meiotic errors to be associated with either ultrasound abnormalities, growth problems or detectable levels of trisomy in small samples of prenatal CVS. Currently, there is no evidence that somatic errors, which lead to confined placental trisomy, are of any clinical consequence.
This leaves unprotected vessels running over the cervix and in the lower uterine segment. This has been demonstrated using serial ultrasound. Oyelese et al. found that 2/3 of patient with vasa previa at delivery had a low-lying placenta or placenta previa that resolved prior to the time of delivery. There are three types of vasa previa.
Ultrasound showing placental abruption. Placental abruption is suspected when a pregnant mother has sudden localized abdominal pain with or without bleeding. The fundus may be monitored because a rising fundus can indicate bleeding. An ultrasound may be used to rule out placenta praevia but is not diagnostic for abruption. [8]
