Ethiodol

Ethiodol, also known as Ethiodized oil, is a sterile, oil-based contrast agent primarily used in diagnostic and interventional radiology procedures. It is a mixture of iodine and ethyl esters of fatty acids derived from poppy seeds, which provides radiopacity owing to its high iodine content. Ethiodol has been utilized extensively for lymphatic and vascular imaging, including lymphangiography and embolization procedures.

Its high viscosity and radiopacity make Ethiodol suitable for selective vessel embolization and tumor localization. In hepatic interventions, Ethiodol is employed in transarterial chemoembolization (TACE) for hepatocellular carcinoma, where it acts as a carrier and imaging agent for therapeutic agents. Additionally, Ethiodol can help delineate abnormal vascular structures and identify leaks in cases of lymphatic or vascular pathology.

The administration of Ethiodol is generally safe, but potential side effects include allergic reactions, oil embolism, and, in rare cases, pulmonary embolization if the oil enters the venous system. Because of these risks, its use is carefully monitored by healthcare professionals.

Manufacturers of Ethiodol include providers of contrast media, and it is generally supplied in various syringe sizes. Its storage requires protection from light and temperature variations to prevent degradation.

Overall, Ethiodol remains a valuable tool in diagnostic imaging and interventional radiology, especially for vascular and lymphatic system assessments. Its unique properties facilitate precise imaging and targeted treatment, contributing significantly to minimally invasive medical procedures.
