Antepartum haemorrhage, especially in cases of placenta praevia, can present challenges in pregnancy. This condition, where the placenta covers or is near the cervix, requires careful monitoring and may necessitate interventions like ultrasound scans and potential hospital admissions. Risk factors f

Placenta Accreta Syndrome (PAS) is characterized by abnormal placental implantation with firm adherence to the uterine muscle due to the absence of certain layers. Risk factors include previous cesarean section, placenta previa, advanced maternal age, and uterine anomalies. Diagnosis involves ultras

During pregnancy, endocrinological structures like the corpus luteum and placenta play vital roles in the production of hormones such as progesterone and estrogens. Progesterone maintains pregnancy by controlling essential functions like endometrial differentiation, myometrial quiescence, and local

Caesarean section (C/S) is an operative procedure done under anesthesia to deliver the fetus, placenta, and membranes through an incision in the abdominal wall and uterus. The history of C-section dates back to the 17th century, with significant advancements in the modern era. Understanding the anat
