O43.21
Placenta accreta
Clinical Classification Guidelines
Medical Intelligence & Overview
Placenta accreta is a serious pregnancy condition characterized by the abnormal attachment of the placenta to the uterine wall. In this condition, the placental tissue invades the uterine muscles more deeply than normal, which can lead to complications during delivery. Recognizing and understanding placenta accreta is essential for expecting mothers and healthcare providers to manage pregnancies safely and effectively.
Causes & Symptoms
Clinical Causes: Previous cesarean section deliveries Multiple uterine surgeries or procedures, such as dilation and curettage (D&C) Placenta previa (when the placenta covers the cervix) Advanced maternal age (typically over 35 years) Uterine abnormalities or scarring In-vitro fertilization (IVF) pregnancies History of placenta accreta in previous pregnancies
Key Symptoms: Heavy or abnormal vaginal bleeding during or after delivery Difficulty detaching the placenta after childbirth Excessive bleeding that requires medical intervention Uterine tenderness or unusual pain Signs of maternal shock in severe cases No symptoms in early stages; diagnosis often occurs during delivery or imaging studies
Diagnostic & Treatment
Diagnosis Path: Ultrasound examination: often the first step, revealing abnormal placental attachment or increased blood flow Magnetic Resonance Imaging (MRI): provides detailed images of placental invasion, especially when ultrasound results are inconclusive Assessment during cesarean section: direct visualization and examination of the placenta Histopathological examination: analysis of placental tissue after delivery or miscarriage, confirming invasion patterns
Treatment Protocols: Scheduled cesarean delivery: often performed around 34-36 weeks of pregnancy to minimize complications Surgical interventions: including removal of the placenta or hysterectomy in cases of severe invasion Blood transfusions: may be necessary due to potential heavy bleeding Interventional radiology: procedures like uterine artery embolization to control bleeding Postpartum care: close monitoring for bleeding or signs of infection Future pregnancies: may require extensive counseling, and risks should be discussed with healthcare providers
