Peripheral arteriovenous malformation: diagnosis and localization by intraarterial injection of technetium-99m-MAA.
Radionuclide angiography with technetium-99m-labeled macroaggregates of albumin (99mTc-MAA), was successful in a single patient with a lower limb arteriovenous (AV) malformation, not only in diagnosis and quantitation of AV shunting, but also in localizing the site of shunting. This information proved useful to the angiographer, permitting a carefully tailored examination of the area of interest. This technique may hold promise as a preliminary examination in patients with limb AV malformations prior to angiography.
