Patient's question:
Pelvic scan showed: No abnormal density in the pelvis. Routine sterile dressing, after dilation, the catheter was inserted smoothly. After injecting contrast agent via the catheter, continuous X-ray images were taken: the uterus was filled with contrast, curved, normal size, smooth edges, slightly right-sided, both fallopian tubes showed contrast filling but not unobstructed, soft, the isthmus portion had normal morphology, the ampulla and fimbriae showed cystic hydrops. When enhanced pressure was applied, contrast entered the left fallopian tube and diffused into the pelvis; after repositioning the catheter, contrast entered the right fallopian tube and diffused into the pelvis. About 300 mL of contrast was infused into the fallopian tubes. 20 minutes later, pelvic X-ray showed contrast accumulation and diffusion. Why was there no visible contrast in the uterine cavity?Doctor's answer:
Reflux of contrast agent occurs in two situations: one is flowing into the veins, and the other is outside the uterus. Flowing into the veins is related to endometrial inflammation, while flowing outside the uterus is related to the doctor's operation. According to the report, the left fallopian tube is unclear, and it is highly likely that there is a recurrence of obstruction in the interstitial part. This condition is often caused by chronic endometrial inflammation of the fallopian tube. Your situation requires additional treatment, and before self-healing, it is best to take effective contraceptive measures to prevent the possibility of ectopic pregnancy.
