Scintigraphic localization of therapeutic gelatin emboli were evaluated during and after transcatheterarterial embolization (TAE) in nine patients. Focal uptakes in the spleen suggesting adverse embolism were notedin three of 7 patients with hepatic neoplasms. Two of which were confiremd by CT. Scintiscan of the patient withdural arteriovenous malformation obtained during TAE demonstrated adverse pulmonary embolism, which dictatedchange in procedure. Scintiscan during TAE showed no advers deposition of the injected emboli in the patients withhemangioma of the back, who was safely treated by TAE. Scintigraphic study during or after TAE using radiolabeledgelatin particle with 99mTc seemed to be a useful modality for early detection of adverse embolism and forprevention of serious complications.
