Volvulus in pediatric ultrasound refers to the twisting of a segment of bowel, most commonly the small intestine, around its mesentery. This severe condition can obstruct blood flow, leading to bowel ischemia and necrosis, and is a medical emergency requiring urgent diagnosis. In infants and children, symptoms like bilious vomiting, abdominal pain, and distension are key indicators.
Ultrasound plays a crucial role in the rapid identification of pediatric volvulus, often revealing the characteristic “whirlpool sign” – a spiraling appearance of the superior mesenteric artery and vein. Early recognition through sonography is vital for prompt surgical intervention, significantly improving patient outcomes and reducing morbidity.
