ultrasonography and placenta previa; does measurement of the os placenta distance predict outcome J Ultrasound Med 1996; 15: 441-446.
The pubovisceral muscle (PVM) anatomy of 30 female cadavers was analyzed via 3D translabial
ultrasonography to confirm LMA.
The use of transabdominal ultrasound in the evaluation of lower urinary tract and pelvic floor dysfunction was first documented in the early 1980's with translabial
, transrectal, and transvaginal technique developed somewhat later.
Patients were then referred for a carefully directed translabial
ultrasound scan of the rectum and anal sphincters.
Furthermore, the translabial
or transperineal technique is not always successful because of reduced visualization secondary to bowel gas (39).
or transvaginal scanning can be helpful in evaluating a patient with suspected placenta previa.
Though no prospective, randomized trial has compared transvaginal with translabial
sonography in the imaging of placenta previa, TVS is safe and well tolerated, with no increase in bleeding.
Transperineal or translabial
sonography can be used where vaginal access is difficult.
In this case, translabial
ultrasonography may be able to locate the mesh laterally.
Safer and more accurate than manual evaluation or translabial
ultrasound, transvaginal ultrasound is "uniquely suited" to determine the management of placenta previa, placenta accreta, and vasa previa.
2A and 2B) However, to meet more complex imaging needs, researchers are developing translabial
and introital ultrasound (ie, between the labia at the vaginal opening) techniques to diagnose and evaluate urinary incontinence.
SAN FRANCISCO -- Consider asking pregnant women to make an autologous blood donation if translabial
or endovaginal ultrasounds show the placenta within 2 cm of the internal os, Dr.
