placental abruption
Premature separation of the placenta from the uterine wall before delivery, causing maternal and fetal complications.
Full Definition
A serious obstetric emergency characterized by the premature detachment of a normally implanted placenta from the uterine wall before the third stage of labor. This condition can be partial or complete and may present with vaginal bleeding, abdominal pain, uterine tenderness, and fetal compromise. Risk factors include hypertension, trauma, previous abruption, and substance abuse. Diagnosis relies primarily on clinical findings, as ultrasound may not detect all cases. Management depends on gestational age, severity, and maternal-fetal status, ranging from observation to immediate delivery.
