主动脉球囊阻塞术在控制骶尾部手术出血中的应用

进行骶尾部肿瘤根治手术时常常会出现危及生命的大出血。当前，有效、安全地控制这类出血仍是一个难题。在此我们报道在骶尾部肿瘤切除手术中应用球囊间歇阻塞腹主动脉远端来控制出血的一种方法。球囊管由股动脉插入，并进入腹主动脉。操作中，通过比较双侧脚趾的氧饱和度信号和超声定位来引导和确保球囊进入腹主动脉中肾动脉远端的位置。腹主动．脉内血流每阻断60分钟就开放10分钟。在进行骶尾部肿瘤切除手术的5例患者使用球囊阻塞后，失血量均小于300ml，手术时间短于2小时。手术后患者的肾脏、盆腔脏器以及下肢功能未出现明显改变。故经皮主动脉球囊阻塞术可对骶尾部肿瘤切除手术中出血进行有效而安全的控制。

Radical sacral surgery can be associated with life-threatening blood loss. Effective and safe methods for controlling this blood loss remain elusive. We here report the use of an inflatable sizing balloon to intermittently occlude the distal abdominal aorta and control blood loss during sacral tumor resections. The balloon catheter was introduced into the abdominal aorta via the femoral artery. Pulse oxygen saturation signals from bilateral toes and ukrasonography were used to guide and confirm the location of the balloon in the abdominal aorta and distal to the renal arteries. The balloon was deflated for 10 min after each 60 min occlusion period. In five patients undergoing sacral tumor resection, the estimated blood loss when using balloon occlusion was 300 ml, and surgical duration was 〈2 h. No significant change in kidney, pelvic organ, and lower extremity function was found after the surgeries. Percutaneous aortic balloon occlusion can provide safe and effective control of blood loss during sacrococcygeal tumor resection.
