What is spillage in HSG?
medium is the dye used during the test and spill on either side means the Fallopian tubes are patent and hence the dye went through the uterus to the tubes and spilled in d peritoneal cavity…
What is Intravasation of contrast in HSG?
Intravasation implies backflow of injected contrast into the adjoining vessels mostly the veins. The contrast passes from the uterine cavity directly into the myometrial vessels with subsequent drainage to the pelvic veins. The prevalence of intravasation has been reported to be 0.4–6.9% [7].
What is filling defect in HSG?
If a “filling defect” (an area where the dye does not fill the uterine cavity) is seen in the uterine cavity, it is possible that a fibroid, polyp or scar tissue is present. A fibroid is a benign smooth muscle tumor of the uterus. Fibroids are very common and present in up to 40% of all women.
What contrast medium is used for HSG?
Both oil-based and water-based iodinated contrasts are used for HSG. The advantages and disadvantages of each have been debated for years. Most studies ultimately fail to show a difference in the diagnostic accuracy of uterine or tubal pathology with either of these media.
What contrast is used in HSG?
HSG using low osmolar contrast media (Iopramide and Ioxaglate) demonstrated diagnostic image qualities similar to HSG using conventional high osmolar contrast media (Iodamide). However, all three contrast media were found to be too dense for the detection of intrauterine pathology.
What is the difference between intravasation and extravasation?
The entry of tumor cells into the circulation (intravasation) and the exit of tumor cells from the circulation (extravasation) to host tissue represent critical steps in the metastatic process.
What is Loculated spill?
Loculated spillage of contrast in the peritoneal cavity is seen as oval, irregular, or bizarre shaped collections of contrast near the fimbrial end of the tube. A radiolucent halo may be seen separating the loculated peritubal collection from the dilated tube, known as the “halo sign” (Fig. 7).
Can HSG see polyps?
Commonly performed to determine if the fallopian tubes are open, an HSG can also reveal abnormalities of the inside of the uterus, such as polyps, fibroids, adhesions, and/or a uterine septum.
How much contrast is used in HSG?
Design: For modified hysterosalpingography, 1–2 mL of water-soluble contrast medium were injected to visualize the uterine cavity, followed by injection of 10 mL of saline to check tubal patency and spillage. A control group of patients underwent hysterosalpingography with undiluted contrast medium.
