Modified Transabdominal Oocyte Retrieval Guided by Vaginal Ultrasound Probe: A Case Report and Literature Review

For patients with ectopic ovaries undergoing in vitro fertilization-embryo transfer, transabdominal ovarian puncture remains necessary for selected cases. Despite advancements in the procedure, transabdominal oocyte retrieval demands higher operational skills compared to transvaginal retrieval. In this study, a retrospective analysis was conducted on the clinical data and treatment process of a patient with a unilateral ectopic ovary, undetectable by vaginal ultrasound, who underwent transabdominal ovarian puncture for oocyte retrieval under the guidance of a vaginal ultrasound probe. By employing a towel clip to grasp and indent the abdominal skin, simulating a vaginal fornix-like structure, the vaginal ultrasound probe was flexibly positioned on the smooth abdominal wall, facilitating the oocyte retrieval process and ensuring its smooth execution. A significant number of oocytes were successfully retrieved, resulting in a successful pregnancy and term live birth. This modified technique, which further optimizes the operational process, is an efficient and reliable method for transabdominal oocyte retrieval.
