Splanchnic artery pseudo-aneurysms secondary to blunt abdominal trauma in children☆

Abstract 

Traumatic splanchnic artery pseudo-aneurysms are uncommon; only two cases have been reported among the pediatric population. The authors describe their experience with four patients in whom splanchnic artery pseudo-aneurysms developed after blunt abdominal trauma. Splenic artery pseudo-aneurysms were found in a 6-year-old boy and an 8-year-old girl after blunt splenic injuries. In both cases, spontaneous thrombosis of the pseudo-aneurysms occurred after a period of observation. Hepatic artery pseudo-aneurysms were found in a 7-year-old boy and a 10-year-old girl after major liver lacerations. The boy had successful angiographic embolization of the lesion, but the girl required direct ligation of the pseudo-aneurysm after nearly exsanguinating from acute hemorrhage. All four children have recovered completely, with no long-term sequelae. Traumatic splanchnic artery pseudo-aneurysms are potentially life-threatening complications that can occur after blunt abdominal trauma. The investigation and management of these lesions must be individualized according to the clinical scenario.
