Infection usually begins as endometritis and involves the endometrium and any retained products of conception. If not treated, the infection may spread further into the myometrium and parametrium. Parametritis may progress into peritonitis. The patient may develop bacteremia and sepsis at any stage of septic abortion. Pelvic inflammatory disease (PID) is the most common complication of septic abortion.
Hysteroscopy is the method of choice or the evacuation of retained products of conception as it offers the warranty that not even the slightest amount of tissue has been missed.
