Cesarean scar pregnancy (CSP) is an uncommon form of ectopic pregnancy resulting from implantation of a blastocyst within myometrial scar tissue in the anterior lower uterine segment
(LUS), at the site of prior Cesarean section.
The ones that were confined to the lower uterine segment
and mid-body were much harder to detect.
Washington, Jan 31 (ANI): Researchers have revealed that by measuring the lower uterine segment
(LUS) thickness, doctors can predict uterine scar defects in women who had previous caesarean deliveries, and anticipate which patients are at risk for subsequent uterine rupture if they have a trial of labour.
Accreta also can occur if the placenta implants over a submucosal fibroid located in the lower uterine segment
, near the rudimentary uterine horn or near the uterine cornu.
These findings were confirmed by the Department of Radiology which described an anterior placenta extending along the lower uterine segment
with multiple retro-placental vessels invading the myometrial wall and placenta extending into the posterior wall crossing over the internal cervical os.
An abdominal computed tomographic scan showed the presence of a lobulated pelvic mass arising from the right lower uterine segment
, with left lateral displacement of the bladder.
Sweeping involved separating the membranes from the lower uterine segment
as far as possible with a finger inserted into the internal os.
Active bleeding was detected from the varicose veins posterior of the lower uterine segment
In an earlier report from our institution, we showed that the dominant hand of the operator becomes heavily contaminated with bacteria during the process of extracting the fetal headfrom the lower uterine segment
ACOG's 2012 Practice Bulletin on Prediction and Prevention of Preterm Birth, which does not mandate universal screening but supports its consideration, notes that, "if second trimester transabdominal scanning of the lower uterine segment
suggests that the cervix may be short or have some other abnormality, it is recommended that a subsequent transvaginal ultrasound examination be performed to better visualize the cervix and establish its length" (Obstet Gynecol.
