Pseudoaneurysm in arteria temporalis treated by thrombin infusions

A patient presented with a pseudoaneurysm (PA) in the frontal branch of the temporal artery following blunt trauma. The chosen treatment method was percutaneous ultrasound-guided thrombin injection. Several weeks after the initial infusion, Doppler imaging revealed residual flow within the PA, prompting a second injection. At the final follow-up, the PA was partially thrombosed, and it was determined that it would resolve over time. Several months later, the patient reported a continued reduction in the size of the PA.
