Valsalva Maneuver후 발생한 자발성 상갑상동맥 파열 1예

Spontaneous arterial rupture in the neck resulting in cervical hemorrhage and hematoma is rare and may progress to life-threatening conditions. We describe a case of 59 year old man who visited the emergency department, presenting with acute right neck swelling after repetitive Valsalva maneuver. Computed tomography scans revealed a hematoma in the right upper neck and a leakage of the contrast media at the first branch of the external carotid artery which is the superior thyroid artery. Although the patient developed cervical hemorrhage and hematoma, but spontaneously subsided with no intervention in 4days. Here we report, with a literature review, this extremely rare case of spontaneous superior thyroid artery rupture. (J Clinical Otolaryngol 2016;27:375-378)
