An aortography performed on the second day of admission demonstrated complete occlusion of the aorta below the renal arteries with well-developed collaterals and no intraluminal filling defects, suggestive of an old aortic occlusion.
Tc-99m PYP scintigraphy was performed on the third day of admission, and showed diffusely increased uptake in the lower abdomen and pelvic area as well as in the right calf (outlined areas). At that time the CPK level had decreased to 27,725 IU/L. The explanation for the clinical presentation was unclear but was probably related to a temporarily occlusion of an already compromised circulation. The anesthesia of the lower extremities rapidly resolved in the first days of the admission.
