A patient with placenta percreta at 28+3 weeks of gestation, whose placenta invaded the bladder was reported in this article. Under a multidisciplinary collaboration mode, combined with obstetric ultrasound evaluation, an abdominal aortic balloon was pre-installed before surgery, and cesarean delivery followed by total hysterectomy and partial bladder resection and repair were performed during the operation. Although the balloon was not inflated intraoperatively, the patient still developed arterial thrombosis at the puncture site postoperatively and recovered well after thrombectomy treatment. This case can provide clinical references for perinatal management of similar high-risk pregnancies.
