Placenta accreta spectrum disorder complicating a second trimester miscarriage.

Placenta accreta spectrum (PAS) disorder is a potentially life-threatening condition which rarely complicates second trimester miscarriages. This report describes a woman who was pregnant at 17 weeks with a history of previous caesarean section and uterine curettage. She presented with hypovolaemic shock following massive per-vaginal bleeding at home. A 180 g fetus was spontaneously aborted, but the placenta was retained in the uterus. After resuscitation, she underwent surgery, during which a morbidly adherent placenta was identified necessitating an emergency hysterectomy. Histopathological examination confirmed placenta accreta. This case highlights the risk of PAS complicating second trimester pregnancies and underscores the importance of early recognition and intervention to enhance maternal outcomes.
