Leakage of a liquid 188Re-filled balloon system during intracoronary brachytherapy. A case report

We are reporting the first case of an accidental radioactive 188Re leakage of a liquid-filled balloon system. Different analytical methods estimated that approximately 4 mCi 188Re were released. The radiation burden was reduced considerably by the combined therapy with perchlorate and forced volume diuresis. Estimated exposures to all organs were very low with 1.8 rad. A total body nuclear scintigraphy demonstrated uniform 188Re distribution, without specific organ concentration.
