Pathophysiology
Placenta previa is initiated by implantation of the embryo (embryonic plate) in the lower (caudad) uterus.
With placental attachment and growth, the cervical os may become covered by the developing placenta.
A defective decidual vascularization exists, possibly secondary to inflammatory or atrophic changes.
Symptoms
Bright red bleeding from the vagina during the second half of your pregnancy. It can range from light to heavy, and it's often painless.
Contractions along with the bleeding. You might feel the cramping or tightening that comes with contractions, or feel pressure in your back.
Diagnosis
To diagnose placenta previa, the patient must undergo the following diagnostic procedure.
Ultrasound. Early detection of placenta previa is always possible through ultrasonography. It is the most common and initial diagnostic test that could confirm the diagnosis.
