Feto-Maternal Outcome of Placenta Praevia after Previous Cesarean Section in a Tertiary Care Hospital

Placenta praevia is a rare form of impaired placentation where placenta lies low in uterine cavity, covering completely or partially the internal cervical ostium. Thefrequency of placenta praevia at the time of delivery average 1/200 births i.e.0.5%. 

 Low implantation is observed in 28% of pregnancies before 24 weeks, 18% after 24 weeks but at term it is only 3%. The prevalence of placenta praevia is significantly over estimated due to practice of routine mid-pregnancy scan, and many women currently undergo a repeat scan in late pregnancy for placental localization. The prevalence of placenta praevia (2.58%) was seen in 3rd and higher gravida group. It also showed an increase with age; the highest number of the patient (38.8%) was between 31-36 years and the lowest between 26-29 years (16.7%). Endometrial trauma due to abortion followed by Dissection & Evacuation (D&E), diagnostic D & E, uterine scar from myomectomy, uterine adhesion, endometritis are predisposing factor to placenta praevia.
