Pseudoaneurysm and Arteriovenous Fistula in the Radial Artery after Cardiac Catheterization: A Case Report.

We report the case of a 71-year-old man who was experiencing a gradually worsening, dull pain and a cold sensation in his right hand. Three months earlier, he underwent a percutaneous coronary intervention for angina pectoris using a transradial approach in his right wrist and developed an arteriovenous fistula (AVF), a complication of percutaneous coronary intervention. Ultrasonography and computed tomography revealed a pseudoaneurysm and an AVF that were reducing the blood flow in his right hand.
