The pregnancy of a patient with placenta membranacea associated with placenta increta and a live-born infant is described, and the literature covering placenta membranacea is reviewed. A total of 26 cases of placenta membranacea in the second and third trimesters have been reported. The condition appears to have an incidence of 1:20,000-40,000, and there have been 14 reported live births associated with this rare placental anomaly. Antepartum and postpartum hemorrhage were reported to complicate 83 and 50% of the cases, respectively. Approximately 30% of the cases involved some form of abnormal placental adherence.

Fetal Circulation01:14

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
