Abstract
Background: Splenic laceration is the most common injury following blunt abdominal trauma. The injury is characterized by the presence of parenchymal laceration; however, vascular lesions may also be seen such as pseudoaneurysms. Multiple pseudoaneurysms are rare complication. Delayed treatment is traditionally with splenectomy, however, small case series of the use of embolization have been described. Case Presentation: A 29-year-old female presented with left upper quadrant pain 22 days after a motor vehicle accident; she was hemodynamically stable. Computed tomography imaging with contrast enhancement demonstrated American Association Staging of Trauma grade IV splenic artery injury with multiple large splenic artery pseudoaneurysms. The patient proceeded to angiography and was treated with proximal coil embolization. Ultrasound demonstrated pseudoaneurysm thrombosis at 4 days and again at 6 weeks after treatment. Conclusion: This case demonstrates the success of splenic artery embolization in achieving non-operative management of blunt splenic injury in a sub-acute setting, even with the presence of multiple large splenic artery pseudoaneurysms.
