Ultrasound-guided thrombin injection for the treatment of iatrogenic pseudoaneurysm of the right brachial artery

Iatrogenic vascular injury is an abnormal state that occurs in patients as a result of inadvertent or erroneous treatment by physicians or surgeons. Pseudoaneurysms need to be distinguished from true aneurysms. Pseudoaneurysm is a dilatation of an artery with actual disruption of one or more layers of its wall, rather than with expansion of wall layers. Recently, several reports have suggested that ultrasound-guided thrombin injection is a safe, effective, and rapid therapy for the treatment of pseudoaneurysm and without being associated with the limitations of ultrasound-guided manual compression.We report a case of a 38-year-old patient who had brachial artery pseudoaneurysm and was successfully managed with ultrasound-guided thrombin injection.
