AbstractA patient with a large airway venous malformation underwent anesthesia for a tooth extraction. The procedure was uneventful until extubation, immediately after which complete airway obstruction resulted. After unsuccessful attempts to relieve the problem, the patient's trachea was reintubated. Laryngoscopy showed that the venous malformation in the airway had enlarged and was responsible for the airway obstruction. Another attempt at extubation after corrective maneuvers was again unsuccessful. A tracheostomy was required, which was eventually removed after a complete recovery. Anesthesiologists must be concerned with any airway vascular abnormality. Most abnormalities involving the airway are either hemangiomas or venous malformations. The anesthesiologist must diagnose the problem correctly because even minor manipulation of a venous malformation may result in exsanguination, or the malformation may become engorged and compromise the airway.
