title: Superior mesenteric artery syndrome: an unusual cause of intestinal obstruction in brain-injured children.
abstract: Superior mesenteric artery syndrome is a rare cause of upper intestinal obstruction in both adults and children. Sixteen children with severe traumatic brain injury and spastic quadriparesis developed small intestinal obstruction while undergoing a rehabilitation programme between 1981 and 1990. Five patients met the roentgenographic diagnostic criteria. The presenting symptom was post-prandial bilious vomiting. The mean age was 13 (10-16) years. The mean time clapsed from injury to diagnosis was 53 days and from rehabilitation admission to diagnosis 22 days. The mean delay in diagnosis after onset of symptoms was 4 days. All patients were of disproportionately lower body weight in relation to height, with a mean weight loss of 7 kg. The mean percentile for weight was 18 and height 58, with a difference of 30 between height and weight percentiles. The patients were receiving nasogastric or gastrostomy tube feedings at the onset of the symptoms. All patients were treated non-surgically with gastric aspiration, nasojejunal or gastrojejunal feeding by passing a feeding tube distal to obstruction. No patient required intravenous hyperalimentation. There was no recurrence in any patient during the follow-up period of 1-5 years. Though rare, superior mesenteric artery syndrome can develop in brain-injured children with spastic quadriparesis, prolonged recumbency and recent weight loss. Increased awareness of occurrence of this condition and timely management will decrease morbidity and complications that may interfere with recovery.
