A 7-year-old boy falls from playground equipment and lands on his outstretched hand. Radiographs show a supracondylar fracture of the humerus. His forearm is cool, radial pulse is diminished, and several hours later he develops severe pain with passive finger extension. Injury to which of the following vessels is most likely responsible?
- A)Radial artery
- B)Brachial arteryGABARITO
- C)Ulnar artery
- D)Axillary artery
- E)Profunda brachii artery
