Placenta accreta is a relatively rare event, in which the placenta is abnormally implanted into the uterine myometrium. The most significant complication is intense bleeding, mainly during labor. The incidence of placenta accreta increased during the last years due to the increase in cesarean delivery rate, which is the main risk factor. Pre-cesarean diagnosis of placenta accreta may improve surgical outcome. Early diagnosis allows appropriate preparation of multidisciplinary team (including, among others; OB-GYN, urologists, anesthesiologists, neonatologists) and massive blood products. Pre-cesarean diagnosis is based on imaging, mainly ultra-sound. This modality has significant false positive rate which may result in extreme sources investment and even indicated pre-term labor, in vain. Volatolome is a complex of volatile markers emitted in several processes in the human body and collected from breath, skin, urine, blood, feces and more. This profile may be used to identify volatile markers for specific medical conditions. NA-NOSE is an electronic device knowing to identify differences in the Volatolome between "healthy" and "sick" subjects. The objective of this study is to identify specific volatile profile for placenta accreta which will help to distinguish between women with placenta accreta and those without.
