In vitro fertilization represents a risk factor for vasa praevia.

ABSTRACT

Vasa praevia is a rare but very dangerous obstetrical condition. The purpose of our article is to evaluate data available in literature that indicate in vitro fertilization as a risk factor for vasa praevia. PubMed Library and Cochrane Database were searched using the keywords vasa praevia, in vitro fertilization, velamentous cord insertion, placenta praevia. The conditions related to in vitro fertilization that increase the risk of vasa praevia formation were identified and discussed. Also, the diagnosis and management options were reviewed. In vitro fertilization represents a risk factor for vasa praevia and all such pregnancies should be screened by transvaginal ultrasound for vasa praevia.
