Abstract
Superficial temporal artery (STA) pseudoaneurysm is a very rare disease. We report the treatment of an STA aneurysm by ultrasound-guided thrombin injection (UGTI). The patient was an 85-year-old woman, who had hit her temple 3 weeks ago. Subsequently, a pulsating mass formed at the site of injury, and she developed a throbbing pain. STA pseudoaneurysm was diagnosed by ultrasonography and CT angiography, and UGTI was performed. The aneurysm was successfully occluded by injection of 1,200 units of thrombin into the aneurysm sac. There were no complications or side effects, and she did not require hospitalization.
