Clinical complications after transvaginal oocyte retrieval: a retrospective analysis.

There are little systematic data reported in the literature on complications observed after transvaginal oocyte retrieval (OR) guided by ultrasound. We report our experience in 542 in vitro fertilisation cycles. The frequency of severe complications in our patients was 0.72%; of these, two cases were bronchospasm during anaesthesia (0.36%) and two were cases of intraperitoneal bleeding (0.36%); minor vaginal bleeding was the most frequent complication (18.08%), which was treated easily. Through this retrospective analysis, it is evident that clinical suspicion is of particular importance in detecting post-OR complications on one hand, but on the other these complications are rare and most are treated conservatively.
