A Case of Pseudoaneurysm of the Superior Thyroid Artery after Core Needle Biopsy

ABSTRACT

A pseudoaneurysm is a collection of blood that locates between the two outer layers of an artery, the muscularis propria and the adventitia. It is resulted from disruption of a portion of the arterial wall. A pseudoaneurysm can be caused by trauma, blood vessel intervention, intravenous drug use, vasculitis, infectious aneurysm, and postoperative anastomotic leakage. The pseudoaneurysm of superior thyroid artery after core needle biopsy is rare. We report a case of pseudoaneurysm caused by thyroid core needle biopsy and treated by surgical treatment.
