Torso vascular trauma

Abstract

Vascular injury within the chest or abdomen represents a unique challenge to the pediatric general surgeon, as these life- or limb-threatening injuries are rare and may require emergent treatment. Vascular injury may present as life-threatening hemorrhage, or with critical ischemia from intimal injury, dissection, or thrombosis. Maintaining the skillset and requisite knowledge to address these injuries is of utmost importance for pediatric surgeons that care for injured children, particularly for surgeons practicing in freestanding children's hospitals that frequently do not have adult vascular surgery coverage. The purpose of this review is to provide an overview of torso vascular trauma, with a specific emphasis in rapid recognition of torso vascular injury as well as both open and endovascular management options. Specific injuries addressed include blunt and penetrating mediastinal vascular injury, subclavian injury, abdominal aortic and visceral segment injury, inferior vena cava injury, and pelvic vascular injury. Operative exposure, vascular repair techniques, and damage control options including preperitoneal packing for pelvic hemorrhage are discussed. The role and limitations of endovascular treatment of each of these injuries is discussed, including endovascular stent graft placement, angioembolization for pelvic hemorrhage, and resuscitative endovascular balloon occlusion of the aorta (REBOA) in children.
