Postpartum uterine infection with Clostridium perfringens

Clostridium perfringens is commonly present in the female genital tract. Uterine infection with this organism is a potentially fatal disease infrequently seen in obstetric practice. The manifestations of C. perfringens uterine infection are variable, ranging from endometritis to gas gangrene with fulminant septicemia. The usual precipitating event has been septic abortion, but such infections can also occur spontaneously in uterine tumors and after complicated deliveries requiring mechanical intervention. Diagnosis may be aided by radiologic techniques, and treatment involves high-dose penicillin and possibly surgery. We report two cases and review the clinical presentation and the diagnostic and therapeutic aspects of this disease.
