chromoperturbation
Pronunciation: kro-mo-per-tur-BAY-shun
Injection of methylene blue dye through the cervix to assess fallopian tube patency during laparoscopy.
Full Definition
A diagnostic procedure performed during laparoscopy to evaluate tubal patency for fertility assessment. A dilute methylene blue solution is injected through the cervix via a cannula, and the surgeon observes whether dye spills from the fimbrial ends of the fallopian tubes into the peritoneal cavity. This test helps identify tubal blockages, hydrosalpinx, or other abnormalities that may affect fertility. The procedure is often combined with other laparoscopic fertility procedures.
Usage
Usage note: Note the spelling difference from 'chromopertubation' - both forms appear in literature.
