Traumatic False Aneurysms of Peripheral Arteries in Children

摘要

ANEURYSMS are blood-filled cavities that communicate with the lumen of an artery. An aneurysm is classified as “true” or “false” according to its cause and the composition of its surrounding wall. A true aneurysm contains all vessel wall layers and is generally the result of degenerative changes such as those due to atherosclerosis. A false or pseu-doaneurysm is bounded only by fibrous tissue and is lacking in muscular layers. False aneurysms are most frequently the result of penetrating or blunt trauma.False aneurysms have rarely been described in children. We report a case of false aneurysm involving the radial artery of a child. We also discuss the characteristics and differential diagnosis of false aneurysms involving peripheral arteries of children.
