âThe Machineâ International Trailer. The Machine is being hailed as one of 2014's best sci-fi thrillers. Coming to U.K. theaters this March, the story, from director Caradog W. James, takes place in an impoverished world plunged deep into a Cold War with a new enemy.
The blockage is caused by an adherent plug of mucus that forms over the opening of the fallopian tube(s). In some women, injecting the contrast for the HSG will dislodge the plug with immediate opacification of both of the tubes. Therefore, for some women they only need the HSG to open their tubes.
To determine whether your fallopian tubes are blocked, your doctor may suggest a laparoscopy or a hysterosalpingogram (HSG). In an HSG test, liquid dye is inserted by catheter through the vagina (cervix) into the uterus. Then, X-rays are taken to see if there is a blockage or if the dye flows freely into the abdomen. Another method of HSG uses saline and air rather than dye and ultrasound instead of X-ray. If you have problems with your fallopian tubes, your doctor may recommend surgery to correct the damage or unblock the tubes.
