title: Can Doppler ultrasound-guided oocyte retrieval improve IVF safety?
abstract: Transvaginal ultrasound-guided oocyte retrieval has gained universal acceptance with an excellent safety record overall. However, even with contemporary ultrasound resolution, the aspiration needle can injure adjacent pelvic organs and blood vessels and result in external and internal bleeding. Although the idea that Doppler ultrasound might reduce the risk of blood vessel injury during follicular aspiration seems to be plausable, measurement of peritoneal blood loss and the validity of this opinion has never been appropriately tested. Using a proposed classification method in an IVF programme, it was estimated that a significant peritoneal bleeding occurred in 56/898 (6%) of IVF patients. Although Doppler ultrasound was routinely used in all patients, it did not predict 24/53 (45%) of the patients with moderate peritoneal bleeding. In 8/53 cases (15%) with moderate peritoneal bleeding, vaginal bleeding was also detected and correctly predicted during oocyte aspiration using colour Doppler vaginal vessel imaging. Colour Doppler ultrasound guidance is an easily accessible technology with a theoretical promise to improve IVF safety and, with proper usage, has the potential to reduce haemorrhagic complications.
