摘要
Vascular injuries are a major source of morbidity and mortality in patients with blunt pelvic trauma. Up to 40% of patients with pelvic fractures related to blunt traumatic injury experience intra-abdominal or intrapelvic bleeding, which is the major determining factor of mortality. Sources of hemorrhage within the pelvis include injuries to major pelvic arterial and venous structures and vascular damage related to osseous fractures. Among patients with pelvic fractures, up to 20% require emergent transcatheter embolization, depending on the type of injury. Angiography is the gold standard for the treatment of pelvic arterial hemorrhage associated with pelvic fractures. Transcatheter techniques provide direct identification of sources of bleeding. Selective catheterization and flow-directed particulate emboli can control bleeding from small arteries at sites of injury.
