Abstract:
Objective: To investigate the ultrasonic features of placental abruption (PA) and its outcomes of pregnancy. Methods: Prenatal ultrasonic data of 132 pregnant women diagnosed as PA after delivery were collected, and the ultrasonic findings and pregnancy complications were analyzed. Results: PA was detected with ultrasonography in 48 patients while misses in 84 patients, the detection rate was 36.36% (48/132), and the missed diagnosis rate was 63.64% (84/132). Ultrasound showed placental thickening in 29 cases, intraplacental abnormal echo in 16, retroplacental abnormal echo in 9, placental marginal abnormal echo in 6, abnormal echo at placental fetal surface in 4, abnormal echo between uterine wall and amniotic membrane in 2, abnormal echo in amniotic cavity in 7 cases. The main complications of PA included cesarean section, uterine placental stroke, disseminated intravascular coagulation, postpartum hemorrhage, premature birth, severe neonatal asphyxia and even perinatal death. The incidences of complications in pregnant women with PA detected with ultrasound were higher than those in pregnant women with PA missed with ultrasound (all P<0.05). Conclusion: Prenatal ultrasonic detection rate of PA is low, and the pregnancy outcomes of pregnant women with PA detected with ultrasound is relatively poor.
