Tubal cannulation is a procedure used to try to open a fallopian tube that is blocked at its junction with the uterus (a proximal blockage). A thin catheter or wire is guided through the cervix and into the tube opening, sometimes under X-ray guidance (selective salpingography) or during hysteroscopy, to clear debris or spasm causing the blockage. It is considered for women with a proximal tubal blockage found on HSG, particularly when the rest of the tube and pelvis appear otherwise healthy, and success is assessed by a repeat test to confirm the tube is now open.
Also known as: selective salpingography
