Chromopertubation is a procedure where a colored dye is passed through the fallopian tubes to confirm that they are patent. The procedure is done under anesthesia and it is unlikely that a patient will be aware that it is being done.
A chromopertubation may be called for if a patient is undergoing a surgical procedure where the fallopian tubes are visible. A dye can be introduced into the uterine cavity during the procedure and then observed as it comes out of the ends of the tubes into the peritoneal (abdominal) cavity.
Sometimes tubal occlusion can not be detected by looking at the fallopian tubes, so additional tests may be necessary to provide a full evaluation.
