title: Ultrasound-guided thrombin injection of genicular artery pseudoaneurysm.
abstract: Pseudoaneurysm is a rare complication after arthroscopic procedures involving the knee. A 38-year-old man presented 1 month after right-knee arthroscopy with a 2-cm pulsating mass on the medial side of the right knee. Duplex ultrasound evaluation revealed 2.5 × 2.1-cm pseudoaneurysm just distal to the patella with arterialized flow communicating with the inferior medial genicular artery. Ultrasound-guided thrombin injection was performed in an office setting, and the resolution of active flow within the pseudoaneurysm was confirmed with duplex ultrasonography.
