A case report: Multiple air embolism after the laryngopharyngoesophagectomy occurred by the cervical infection from postoperative fistula

Abstract

Systemic air embolism, a very rare clinical condition, has many causes. We report a case of multiple air embolisms following laryngopharyngoesophagectomy salvage surgery for hypopharyngeal residual cancer after concurrent chemoradiotherapy. Cervical infection arose from a fistula caused by postoperative suture failure in which the 56-year-old man suddenly lost consciousness and went into shock. A few days post operation, an air embolism happened and caused in the brain, pulmonary, myocardiac and cerebral infarction. The man died two months after initial occurrence. We suspect that air entered through the ruptured left internal jugular vein via infection due to aspiration at the injury site. Air embolisms are associated with different medical maneuvers, and it is necessary to recognize that they may become a serious perioperative complication.
