FEW REFERENCES concerning occlusion of the renal arteries by embolism or thrombosis in infants can be found in the recent literature. Gross1 reported two such cases in 1945 and pointed out that arterial embolism and thrombosis in infancy are likely to be commoner than indicated by the number of published cases. Morrison2 in the same year described total ischemic infarction of one kidney in an infant with thrombosis of the abdominal aorta ascribed to a peculiar arteritis.
Blockage of a renal artery leads to albuminuria and passage of blood and casts in the urine. Azotemia, oliguria and anuria and uremia will follow if both renal arteries are affected. The diagnosis of arterial occlusion of the kidneys is difficult unless emboli with resultant infarction appear in the extremities.
Our material contains, in addition to cases of localized infarcts secondary to bacterial endocarditis, five instances of total renal infarction due
