Hystero contrast sonography (HyCoSy) is an ultrasound procedure intended to diagnose structural defects of the female reproductive system, such as blockage of the fallopian tubes. It is conducted as an initial transvaginal ultrasound followed by the introduction of a catheter to force an aqueous fluid up the fallopian tube to provide a contrast ...
Blockage of the fallopian tubes is mainly diagnosed today by hysterosalpingography (HSG) or Hystero Contrast Sonography (HyCoSy) in which either X-ray contrast media or aqueous fluid are forced up the fallopian tube to create an image on X-ray or ultrasound. This image demonstrates (or excludes) the possibility for sperm to swim up and for ova ...
The contrast agent is taken up by the fallopian tubes. [22] Since HyCoSy is performed using transvaginal ultrasound, it is less invasive than chromopertubation. Using a contrast agent, the ultrasound image can be used to detect whether and how the contrast medium flows through the fallopian tubes.
Gynecologic ultrasonography or gynecologic sonography refers to the application of medical ultrasonography to the female pelvic organs (specifically the uterus, the ovaries, and the fallopian tubes) as well as the bladder, the adnexa, and the recto-uterine pouch. The procedure may lead to other medically relevant findings in the pelvis.This ...
A meta-analysis revealed 3.6 times greater odds (OR = 3.6) of pregnancy with oil-based contrast compared to no hysterosalpingography. [5] This effect is thought to be due to the flushing action of the contrast into the uterus that causes dislodgement of mucus plug, debris, or opening of mild adhesions in the fallopian tubes. [6]
However, the testing of patency – whether or not the tubes are open can be carried out using hysterosalpingography, laparoscopy and dye, or hystero contrast sonography (HyCoSy). During surgery, the condition of the tubes may be inspected and a dye such as methylene blue can be injected into the uterus and shown to pass through the tubes when ...
One randomized controlled trial, however, came to the result of a higher perinatal death rate of normally formed infants born after 24 weeks exposed to Doppler ultrasonography (RR 3.95, 95% CI 1.32–11.77), but this was not a primary outcome of the study, and has been speculated to be due to chance rather than a harmful effect of Doppler itself.
Contrast-enhanced ultrasound (CEUS) is the application of ultrasound contrast medium to traditional medical sonography. Ultrasound contrast agents rely on the different ways in which sound waves are reflected from interfaces between substances. This may be the surface of a small air bubble or a more complex structure.
