[Modified cesarean hysterectomy for placenta previa percreta in the third trimester via peritoneum lateral approach]

To investigate the application of modified cesarean hysterectomy for placenta previa percreta in the third trimester via peritoneum lateral approach.

Data of 8 patients at 34 weeks or more gestation, who underwent cesarean hysterectomy for placenta previa percreta in Xiangya Hospital, Central South University, between January 2008 and December 2011, were analyzed retrospectively. The patients were divided into a modified cesarean hysterectomy by peritoneum lateral approach group (modified group, n=4) and a conventional cesarean hysterectomy group (conventional group, n=4), according to the principles of the case-control and the operation performed by the same doctor. The incidence of blood loss, the number of transfusions of RBC, and the ocurrnce of complications were compared between the 2 groups.

The blood loss in the modified group and the conventional group was (2280±687) mL and (6150±2023) mL, and the number of transfusions of RBC was (4.5±2.1) U and (11.7±8.9) U, respectively. There was no coagulation disorder and ureteral injury in the modified group whereas there were 2 disorders and 1 injury in the conventional group. Two patients with bladder laceration were observed in the 2 groups.

Large amounts of bleeding will be onset in the placenta previa percreta. Modified cesarean hysterectomy for placenta previa percreta can reduce the blood loss and the incidence of related complications in the operation.
