Localization of Accessory Renal Artery Infarction Using Tc-99m DMSA Scintigraphy

The presence of accessory renal arteries has been considered a relative contraindication in the setting of a live related renal transplant program. Failure to properly anastomose the arteries can cause segmental infarction leading to increased morbidity. The authors describe a transplant patient with a well-defined cortical defect on a Tc-99m DMSA study, which was caused by a vascular complication. Although Tc-99m DTPA scintigraphy revealed the hypoperfused area, Tc-99m DMSA provided better delineation of the infarcted parenchymal zone.
