Abstract:

The aim was to study the factors related with placenta increta and treatment by retrospectively. The etiology of the placenta incr eta and t he treatments were studied by retrospectively analyzing 40 cases. The incidence of placenta increta in our hospital approxi mated to 1:1 011 and the related risk factors include placenta previa, previou s cesarean delivery, and multiple induced abortion. There were about 75% cases w ith above 2 times of induced abortion, 27.5% cases with cesarean and 55% cases with placenta previa. The incidence of h emorrhage (>500 mL) was up to 62.5% when the patients had the completely placent a pr evia and the diameter of the implanted placenta >5 cm. There were about 86% case s of placen ta previa with serious hemorrhage and the amount of bleeding of above 2 000 mL in the 5 cases in which the placenta was implanted the previous cesarean sectio n scar.The incidence of placenta increta was increased with placenta previa, previous cesarean delivery, and multiple induced abortions. Placenta increta ind uces serious puerperal hemorrhage, especially, the placenta implanted in the pre v ious cesarean section scar. The conservative therapies are very important as we ll as hysterectomy.
