Hyperalimentation for superior mesenteric-artery (cast) syndrome following correction of spinal deformity.

The cast syndrome, recently called the superior mesenteric-artery syndrome, is a well recognized complication that can occur after a body cast has been applied. We are reporting the cases of three patients who had this syndrome following surgical correction of spinal deformity. The complication failed to resolve with the usual non-operative measures but did resolve with treatment by total parenteral nutrition.
