Periprocedural Lactation Considerations After Use of Ethiodized Oil in an Interventional Radiology Patient: A Case Report

We present a case of a lactating patient who underwent lymphangiography with ethiodized oil in interventional radiology for a chyle leak after a modified radical neck dissection. Unlike many contrast agents compatible with lactation, ethiodized oil is unique for its high iodine content, lipophilicity, and long half-life—factors that necessitated cessation of breastfeeding due to expected elevated iodine concentrations in her milk. This case highlights the importance of the anesthesiology team’s vigilance, application of critical thinking, and collaboration in optimizing care for lactating patients and families when utilizing perioperative agents with limited safety data.
