Abstract:
OBJECTIVE:To evaluate the value of selective arterial occlusion in the treatment of placenta percreta in late trimester of pregnancy.
METHODS:Fifteen clinical patients ( gestational age ≥34 weeks), diagnosed with placenta percreta in Xiangya Hospital of Central South University from January 2003 to December 2010, were retrospectively analyzed. According to whether the selective arterial occlusion was used or not, the 15 patients were divided into 2 groups: an arterial occlusion group (n=8) and a non-arterial occlusion group (n=7). Based on the time of occlusion, the arterial occlusion group was divided into a prophylactic occlusion subgroup (n=4) and a remedial occlusion subgroup (n=4) (including 1 patient who was performed after the iliac artery balloon was taken out ). The blood loss, the rate of hysterectomy and complications were compared between the arterial occlusion group and the non-arterial occlusion group.
RESULTS:In all 15 patients, the average amount of blood loss was 3813 mL, and the rate of hysterectomy was 73.3% (11/15). The recent complication rate was 20.0% (3/15, including 2 blood coagulation dysfunctions and 1 lower extremity thrombosis), and long-term complication was not found. The average amount of blood loss in the occlusion group was 2512 mL, the hysterectomy rate was 62.5%(5/8); while the average amount of bleeding was 5549 mL and the hysterectomy rate was 85.7% in the non-occlusion group (6/7). There was significant difference between the 2 groups (P<0.05). The average amount of blood loss and the rate of hysterectomy in the prophylactic occlusion subgroup were lower than those in the remedial occlusion subgroup (1350 mL vs 3600 mL, 60.0% vs 66.7%, P<0.05).
CONCLUSION:Patients with placenta percreta in the third trimester of pregnancy may encounter severe postpartum hemorrhage, and the rate of hysterectomy is high. The amount of blood loss and the rate of hysterectomy may be reduced by the selective arterial occlusion before or in the cesarean section, but cannot be avoided completely.
