Renal Scintigraphy in the Diagnosis of Aortic Dissection Affecting the Renal Arteries

摘要

Aortic dissection type ldquo;Ardquo; in a patient with chronic renal failure is presented. The patient had acute deterioration of renal function, which was thought to be due to renal artery involvement by progression of the dissecting aneurysm. Abdominal CT without contrast enhancement was normal, but renal scintigraphy with Tc-99m DTPA showed aortic dissection with involvement of the renal arteries. Early pharmacologic treatment is indicated in all patients with aortic dissection except for those with vital organ involvement who should be operated. Involvement of the renal arteries, shown on renal scintigraphy, was useful in the case presented to indicate the need for immediate surgery due to the dissection affecting the renal arteries.
