Severe abdominal complications after transvaginal ultrasonographically guided retrieval of oocytes for in vitro fertilization and embryo transfer.

Severe life-threatening complications as a result of ultrasonically guided ovum pick-up for IVF may rarely occur. We report 14 cases, out of 3,656 patients undergoing the procedure, presenting with a clinical picture of acute abdomen. In 9 patients tubo-ovarian and pelvic abscess were diagnosed; 3 were treated by laparotomy, whereas in the other 6, culdocentesis and drainage were performed. In 3 cases severe intra-abdominal bleeding occurred with 1 requiring laparotomy and hemostasis, whereas in the others laparoscopic drainage and hemostasis were sufficient. Ruptured endometriotic cystic masses caused acute abdomen in 2 patients; partial oophorectomy and drainage were essential operative procedures. We conclude that although severe postovum retrieval complications are rare, one has to be aware of their occurrence with the aim of accurate diagnosis and prompt intervention.
