Data on baseline characteristics of pregnant<br>women, pregnancy course and the outcomes during delivery were collected. Placenta previa was diagnosed by ultrasonographgy<br>and /or direct visualization of placental location during cesarean section.<br><strong>Results:</strong> The mean age of the population was 28.4 ± 6.0 years old. Most of these delivered at term gestation (87.4%). The<br>modes of delivery were normal vertex delivery, emergency cesarean section and elective cesarean section which presented<br>in 60.5%, 26.5% and 12.1% of pregnancies respectively. The prevalence of placenta previa was 0.7% (6/843). The factor<br>significantly associated with placenta previa was previous uterine curettage (p = 0.001). The significant outcomes of pregnancy<br>with placenta previa were maternal blood loss >500 mL (P = 0.008) and baby’s APGAR score at 1st minute ≤7 (p = 0.006).<br><strong>Conclusion:</strong> The prevalence of pregnancy with placenta previa in Siriraj Hospital was 0.7%.</p>}, number={6}, journal={Siriraj Medical Journal}, author={Bhutia, Pema Choden and Lertbunnaphong, Triphop and Wongwananuruk, Thanyarat and Boriboonhirunsarn, Dittakarn}, year={2020}, month={Apr.}, pages={191–195} }
