Placenta accreta in placenta previa; frequency of previa with or without scarred uterus

ABSTRACT

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.Cross sectional study. Department of Obst and Gynae Allied Hospital, Faisalabad from 1st June 2007 to 31st May 2008. 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. 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. 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
