Prevention and therapy of massive obstetric bleeding with placenta percreta 3b

Abstract

The objective: to reduce the intra- and postoperative complications, massive intraoperative blood loss during abdominal delivery of pregnant women with placenta percreta 3b using endovascular technique of temporary balloon occlusion of the infrarenal abdominal aorta. Materials and methods. Caesarean section in the uterus fundus was performed in 21 pregnant women with placenta percreta and invasion of perivesical tissue, partial invasion to the posterior wall of the bladder (degree of invasion 3b). The main group included 7 pregnant women who had lower median laparotomy and caesarean section in the uterine fundus with balloon occlusion of the infrarenal abdominal aorta after fetal removal and subsequent hysterectomy without uterine appendages and bladder fundus plastics. The comparison group included 14 pregnant women with caesarean section in the uterus fundus without prior balloon occlusion of the abdominal aorta with subsequent hysterectomy without uterine appendages and suturing of the bladder fundus defect in the area of ​​its invasion of placental tissue. Pregnant women of both groups were representative for age, parity, somatic pathology. The diagnosis in all cases was confirmed by ultrasound examination with Doppler and magnetic resonance imaging. All pregnant women were delivered in 36-37 weeks of gestation. The article also presents a clinical case: delivery of a pregnant woman with placenta percreta and invasion in the posterior wall of the bladder using an innovative technique to minimize blood loss, which was conducted at the Kyiv Regional Perinatal Center. Results. It was determined that delivery by caesarean section with balloon occlusion of the abdominal aorta and subsequent hysterectomy without uterine appendages and bladder fundus plastics reduces blood loss (from 1758.0±110.0 ml to 955.0±70.0 ml), duration of surgery (from 112.0±11.0 min to 87.0±9.0 min), duration of hospitalization (from 11±2 days to 7±1 days), the need for blood transfusions and improves long-term consequences. Conclusions. Innovative technology for temporary balloon occlusion of infrarenal abdominal aorta after cesarean section in the uterus fundus and subsequent hysterectomy without uterine appendages in women with placenta percreta 3b significantly reduces blood loss, the likelihood of massive bleeding, organ damage, duration of hospitalization.
