Radiological classification of retroperitoneal hematoma resulting from lumbar vertebral fracture.

Purpose: Lumbar vertebral fracture (LVF) infrequently produces massive retroperitoneal hematoma (RPH). This study aimed to systematically review the clinical and radiographic characteristics of RPH resulting from LVF.

Methods: For 193 consecutive patients having LVF who underwent computed tomography (CT), demographic data, physiological conditions, and outcomes were reviewed from their medical records.

Case Report: Urgent endovascular treatment of subclavian artery injury after blunt trauma.

Subclavian arterial injury is rare and potentially life-threatening, particularly when it leads to arterial occlusion, causing limb ischemia, retrograde thromboembolization and cerebral infarction within hours after injury. Here we report a blunt trauma case with subclavian arterial injury, upper extremity ischemia, and the need for urgent treatment to salvage the limb and prevent cerebral infarction. A 41-year-old man had a left, open, mid-shaft clavicle fracture and left subclavian artery injury accompanied by a weak pulse in the left radial artery, decreased blood pressure of the left arm compared to the right, and left hand numbness.
