There are few reports of nonpenetrating blunt chest trauma causing traumatic lung cyst. Three young male cases of traumatic lung cysts from motor vehicle accident were reported. Two of them, 25 and 17 years old male, had benign clinical courses by conservative management. ⋯ A left lower lobectomy and a partial resection of left upper lobe was performed 46 days after the injury. Culture of the contents of the abscess confirmed Acinetobacter. His subsequent recovery was uneventful and he was discharged one month after the operation.

The mechanism of complement activation during cardiopulmonary bypass was studied for the prevention. In ten patients undergoing open-heart procedures, the serum levels of complement fractions (C3, C4, and C3 activator) were measured by a single radial immune diffusion method. In four of ten patients, the plasma levels of C3a, C4a, and C5a fractions were studied by the radioimmunoassay 2 antibodies method. ⋯ The lower level of C3 activator shows that C3 activator was not excessively produced during cardiopulmonary bypass. Therefore it can be thought that much C4b2a from classical pathway as well as C3a over-production localizing extra-corporeal circuits and little inhibitors on alternative pathway resulted in increased complement activation. The prevention should be done from these etiologies.
