Complications of FNAB are few and generally minor. The most common complications are minor hematoma, ecchymosis, and local discomfort. Clinically significant hematoma and swelling is exceedingly rare. Inadvertent puncture of the trachea, carotid artery, or jugular vein usually does not cause clinically significant problems and is managed with the application of local pressure.
