Background
In recent years, the incidence of placenta implantation has been increasing with the increase in the proportion of second-time pregnancies and older pregnant women after cesarean section. The main risks of placenta implantation are fatal postpartum hemorrhage and high risk rate of hysterectomy, and even death of pregnant and lying-in women in severe cases.
With the maturity and development of interventional medicine, in recent years, the medicine is gradually matured in the treatment of obstetrical hemorrhage, and especially the cesarean section under the abdominal aortic balloon occlusion becomes a research hotspot, so that the bleeding amount in the operation can be obviously reduced, and the hysterectomy rate is reduced. The key to balloon occlusion of the abdominal aorta is to ensure balloon location (located between the renal artery and the bifurcation of the abdominal aorta), adequate occlusion, time of occlusion and monitoring of complications.
The balloon position can be usually positioned under the mediation of X-rays, but the mother fetus and medical care personnel are affected by the radiation, and the required equipment condition is higher, the operation is inconvenient, the cost is higher, and the clinical popularization and the use are not facilitated.
