Spontaneous hemothorax during general anesthesia.

We report a case of spontaneous hemothorax in a healthy 27-year-old man undergoing elective reconstruction of the right anterior cruciate ligament (ACL) under general anesthesia. In the postanesthesia care unit (PACU), the patient became hypotensive and tachycardic with mid-sternal chest discomfort. A chest roentgenogram revealed an almost complete opacification of the right hemithorax.
