Ultrasound-guided Thrombin Injection to Treat a Traumatic Occipital Artery Pseudoaneurysm

Abstract

We report the use of an ultrasound-guided thrombin injection (UGTI) for the treatment of a traumatic occipital artery pseudoaneurysm. We treated a 96-year-old woman who presented with dementia and difficulty with communication. She crumbled and hit the back of her head and was admitted to our hospital. On the fourth day after hospitalization, she was diagnosed with a traumatic occipital pseudoaneurysm based on ultrasonographic examination and computed tomographic angiography. We performed an UGTI with the injection of 100 units of thrombin into the aneurysmal sac. No complications or adverse effects were reported, and she soon showed disappearance of the aneurysm.
