Abstract
It is well known that there are many complications in stellate ganglion block (SGB). But many of them are transient and severe cases are rare.
We encountered a case of cervical and mediastinal hematoma after SGB which had been performed for a 45-year-old-woman with sudden deafness. On the day of 11th treatment, 9 hours after SGB and hyperbaric oxygen therapy, she felt chest compression and suffered severe dyspnea due to hemothorax and cervical hematoma. Emergency intubation was done and she was on artificial ventilation management for 5 days. Probable cause in this case was bleeding from any cervical vessel flowing into the mediastinum, and then through the pleura, finally causing swelling of the neck and obstruction of the airway.
