Common Carotid Artery Hematoma Following Parathyroid Adenoma FNA.

We present a rare case of a common carotid artery wall hematoma after ultrasound-guided parathyroid fine-needle aspiration. The hematoma was detected within seconds from needle insertion, extending along the common carotid artery wall from the lower neck to the common carotid artery bifurcation, and it was quickly restricted with firm pressure. The patient only reported mild discomfort.
