Evaluating Placental Thickness and Thickness of Uterine Muscle at Placenta Attachment in Prediction of Postpartum Blood Loss in Placenta Accreta

PPH remains the most common cause of maternal mortality all over the world

PPH is a serious complication ) is a serious complication of labor and delivery with an incidence of approximately 5-10% and a mortality rate 0.5:1%

PPH can also be a cause of long-term severe morbidity and approximately 12% of women who survive PPH will have severe anaemia A significant percentage of deaths due to PPH can be due to a lack in assessing bleeding amount. Clinically assessing bleeding through inspection underestimates the actual bleeding volume and depending on haemodynamic abnormalities may be to late as effective countermeasures are often not taken in time so identifying pregnant women at risk of PPH prior to delivery is crucial to prevent PPH .

The leading cause of PPH is thought to be uterine atony - the failure of the uterus to contract fully after delivery of the placenta. PPH resulting from uterine atony is a major preventable cause of maternal morbidity and mortality, especially in developing countries .(B-Lynch et al., 2006)

Risk factors for PPH and its main causes, including weak uterine contractions, birth canal lacerations, placental factors, and coagulation abnormalities have been relatively well studied .
