Abstract

Transvaginal ultrasound guided oocyte retrieval (TVOR) during in vitro fertilization (IVF) treatment was first described in 1985. By virtue of its simplicity and effectiveness, it has gained widespread popularity and has now become the gold standard for IVF therapy. Nevertheless, despite the advantages, the aspiration needle may injure the adjacent pelvic organs and structures leading to serious complications. The most common complications are haemorrhage, trauma and injury of pelvic structures, and pelvic infection. Other complications described include adnexal torsion, rupture of endometriotic cysts, anaesthetic, and even vertebral osteomyelitis. In the last two decades, several reports have described the complications associated with this technique, and tried to address the risk factors and safety issues. However there is wide variation in the way this common procedure is performed, with room for improvement through published guidelines. This article reviews the most common complications reported in literature, summarizes the recommendations made to minimize their occurrence, and raises some of the controversial issues related to the procedure especially that of pelvic infection.
