PLACENTA ACCRETA IN PLACENTA PREVIA

FREQUENCY OF PREVIA WITH OR WITHOUT SCARRED UTERUS

Abstract

Objective: To calculate the frequency of placenta accreta in placenta previa
with or without scarred uterus and compare clinico demographic features of cases with or
without placenta accreta. Study Design: Cross sectional study. Place and Duration of Study:
Department of Obst & Gynae Allied Hospital, Faisalabad from 1st June 2007 to 31st May 2008.
Methodology: 200 patients of placenta previa, 100 with history of previous cesarean section
and 100 without history of previous C-section fulfilling inclusion criteria were taken. They were
evaluated by history, examination and ultrasound noting placental location and type. Placenta
accreta was diagnosed during delivery. Results: Out of 200 patients, frequency of placenta
accreta was significantly increased with history of previous C-section. It was 20% in patients
with previous C-sections and 6% in patients without previous C-sections. Conclusions: Our
data suggests that frequency of placenta accreta is greater in patients with previous C-section
and its frequency increases with increasing number of C-sections especially with anterior and
central placenta previa.
