Pseudoaneurysm of the radial artery diagnosed by bedside ultrasound.

A 42-year-old male presented to the emergency department with pain and swelling of his distal right wrist. Bedside ultrasound placed over the swelling revealed a pseudoaneurysm of the radial artery. The patient received percutaneous thrombin injection of the aneurysm sac followed by direct ultrasound compression therapy of the pseudoaneurysm neck, resulting in thrombosis of the sac. The use of bedside ultrasound by the emergency physician led to appropriate care and proper disposition for definitive management.
