I-30: Late Onset Severe Hemoperitoneum after Transvaginal Oocyte Retrieval: Incidence, Course, and Management

Background Severe ovarian bleeding after transvaginal oocyte retrieval is a rare but potentially life-threatening complication. A late-onset is common and may be associated with an increased risk for ovariectomy. In the present study we analyzed our cases of ovarian bleeding (OB) after oocyte retrieval and compared it with the published cases and studies, including 31 patients. Main outcome measures were how often it happens, risk factors, course, and findings during surgery. We could find that this complication occurs in 0.08% of the cases. The first sign of OB was evident in 33.3% within the first hours after retrieval, and in 93.3% within 24 hours. During surgery, a diffuse OB was found in 13.3%. In four patients, the ovary could not be preserved which was associated with longer time intervals between retrieval and the onset of symptoms as well as between retrieval and surgical intervention In conclusion, severe OB occurs in 0.08% after oocyte retrieval. Late-onset bleedings are common. A longer time interval between retrieval and surgical intervention might put a patient at risk for removing the ovary. MaterialsAndMethods N;Results N;Conclusion N;
