Background: Though an extremely rare complication of arterial cannulation, the incidence of radial pseudoaneurysm may increase with the growing use of extended radial artery access for coronary angiography. Case report: A 57 year-old female presented to the emergency department with painful swelling to the volar radial surface of her right wrist 5 days after a non-emergent transradial coronary angiography. An emergency physician used point-of-care ultrasound to diagnose a radial artery pseudoaneurysm. The high-frequency linear transducer allowed visualization of the arterial wall defect and connection between artery and hematoma on B-mode, turbulent pulsatile flow into the adjacent hematoma using color flow Doppler, and a to-and-fro waveform at the wall defect using spectral Doppler. Due to the size and characteristics of the pseudoaneurysm, as well as her pain and mild distal sensory deficits, it was determined that the patient required prompt operative repair. Discussion: Bedside ultrasound is the most rapid and dynamic imaging modality for making diagnosing a radial artery pseudoaneurysm. Different techniques for treating this condition include conservative care, extended compression, thrombin injection, and surgery. Management primarily depends on the size of the pseudoaneurysm and its associated symptoms. Conclusion: In addition to understanding the pathophysiology and risk factors for this condition, the emergency physician must be adept at using point-of-care ultrasound to both make the diagnosis and characterize its findings to determine management.
