Placenta accreta spectrum (PAS) is a leading cause of massive obstetric hemorrhage, particularly when the placenta is removed or unintentionally disrupted during cesarean hysterectomy. In this video, we demonstrate an alternative surgical approach via the posterior vaginal fornix for performing cesarean hysterectomy in patients with PAS.
A cesarean hysterectomy for a case of placenta percreta was performed using the posterior vaginal fornix approach. This technique focuses on avoiding bleeding due to placental disruption and preventing urinary bladder injury.
We summarize the steps of the procedure, including ligation of the vascular pedicles, entry into the retroperitoneal space to identify vital structures and control bleeding, dissection along avascular plane to delineate organ borders, and posterior culdotomy followed by en bloc uterine amputation to avoid urinary bladder injury and minimize blood loss.
The posterior vaginal fornix approach for cesarean hysterectomy in patients with PAS is an effective technique for minimizing bleeding from the highly vascular placental area. Additionally, it offers the advantage of reducing the risk of unintentional urinary bladder injury, thereby improving surgical outcomes in these challenging cases.
胎盘植入谱系疾病(PAS)是产科大出血的主要原因,尤其是在剖宫产子宫切除术中胎盘被切除或意外受损时。在本视频中,我们展示了一种经阴道后穹窿的替代手术方法,用于对患有PAS的患者进行剖宫产子宫切除术。
采用经阴道后穹窿入路对一例穿透性胎盘植入患者实施剖宫产子宫切除术。该技术着重于避免因胎盘受损导致的出血,并防止膀胱损伤。
我们总结了该手术步骤,包括结扎血管蒂、进入腹膜后间隙以识别重要结构并控制出血、沿无血管平面进行解剖以界定器官边界,以及进行后穹窿切开术,随后整块切除子宫以避免膀胱损伤并减少失血。
对于患有PAS的患者,经阴道后穹窿入路进行剖宫产子宫切除术是一种有效的技术,可最大程度减少来自高血管化胎盘区域的出血。此外,它还具有降低意外膀胱损伤风险的优势,从而改善这些具有挑战性病例的手术效果。
