Unilateral pulmonary edema after two-jaw surgery - A case report

Pulmonary edema is usually bilateral, but can be uncommonly unilateral. Although unilateral pulmonary edema (UPE) can occur owing to various etiologies, it usually occurs at a patient who has an underlying defect or abnormality in the cardiopulmonary system except a case of negative-pressure pulmonary edema. Especially UPE following general anesthesia is a rare complication in a healthy patient. Re-expansion pulmonary edema (REPE) as a cause of UPE mostly occurs when a chronically collapsed lung is rapidly re-expanded after pneumothorax. There are some reports associated with REPE following one-lung ventilation used to facilitate surgery, in which there is no chronically collapsed lung. There are, however, little reported cases of a more acute form of this complication following re-expansion after atelectasis due to only several minutes of an inadvertent main stem bronchial intubation during operation. A report of the occurrence of UPE in a healthy, young male undergoing two-jaw surgery is described.
