Autotransfusion of the ascitic fluid in the treatment of severe ovarian hyperstimulation syndrome.

Three cases of severe OHSS were treated by transvaginal aspiration of the ascitic fluid and autotransfusion of the aspirated fluid. Marked improvement of the symptoms, general condition, and urine output followed the aspiration shortly. No reactions were noticed during or after the autotransfusion. The blood parameters were corrected, and the general condition and urine output continued to improve. The procedure is simple, safe, and straightforward that showed a striking physiological success in correcting the maldistribution of fluid and proteins without the use of heterogeneous biological material.
