title: Effects of contrast agents on the fallopian tube in a rabbit model.
abstract: The authors evaluated the effect of different iodinated contrast agents on the fallopian tube and adnexal tissue in 15 rabbits. Ethiodized oil, an oil-soluble agent, was used in five rabbits. The following water-soluble agents were used: iothalamate meglumine 30% (n = 3), iothalamate meglumine 60% (n = 3), and ioxilan (n = 4). The agents were injected through catheters placed in the fallopian tubes. Fallopian tubes and peritoneal cavities were histologically evaluated. The contralateral tube served as a control. Ioxilan and iothalamate meglumine 30% produced no pathologic response in the tube or peritoneal cavity. Iothalamate meglumine 60% was associated with mild inflammatory infiltrate, mucosal edema, giant cell reaction, and periovarian adhesions that were bilateral but more pronounced on the injected side. Use of ethiodized oil resulted in papillary fibrous adhesions on the ovarian surface, and fat granulomas were seen in the periovarian tissues. The safety of oil-based contrast agents for use in hysterosalpingography is therefore questioned. No significant differences were found among the water-soluble contrast agents.
