Abdominal aortic balloon occlusion in the pelvic and sacral tumor resection: An updated review / 中华骨科杂志

ABSTRACT

Surgical treatment for bone and soft tumors of pelvis and sacrum presents a big challenge, because of the complex anatomy of sacropelvic region, large tumor volume at presentation, rich blood supply to the tumor and visceral involvemen, et al. Therefore, surgical excision and reconstruction are technically difficult for sacropelvic tumors. Extensive intraoperative haemorrhage could be life-threatening, and this issue remains a major concern. How to effectively control bleeding during surgery is critical for successful operation and patient's favorable prognosis. Some previous attempts, such as interventional selective internal iliac artery embolization or manual ligation through an additional anterior approach, were tested to be ineffective. Inspired by the success of resuscitative endovascular balloon occlusion of the aorta (REBOA) which resemble an endovascular tourniquet for traumatic hemorrhagic shock, some researchers have applied this techinique to control surgical bleeding during pelvic or sacral tumor resection.The authors have performed REBOA for more than 1 500 sacropelvic tumr surgeries since 2003 in Peking University People's Hospital. The patient age, the diameter of femoral artery and aorta, atherosclerosis, as well as tumor location, volume and expansion and blood suppy, have to be thoroughly evaluated prior to REBOA administration. Admittedly, the application of REBOA do reduce intraoperative bleeding, shorten the operation duration, improve the safety of surgery, yet some complications were observed including local hematoma at the puncture site, acute arterial thrombosis, femoral artery pseudoaneurysm or occlusio, et al. The purpose of this study is to review the literature on REBOA administration in pelvic and sacral tumors excision, with the focus on its indications, performing procedure, the safety and efficacy, and complications. Moreover, in order to popularize the clinical application of aortic balloon occlusion in the future, we summarize our experience of abdominal aortic balloon occlusion over 10 years.
