The centrifugal pump (bio-pump) as a temporary shunt during the operation of the descending thoracic aortic aneurysms was used as effective means of providing adequate circulation to the lower body. But in the acute excessive bleeding, estimates of the flow to the abdominal viscera as well as spinal cord are variable. We employed bio-pump with an interposed soft reservoir under low dose systemic heparinization in 2 cases of the descending thoracic aortic aneurysms. Both cases had been maintained adequate flow and perfusion pressure in the time of acute excessive hemorrhage, and there were no evidence of the organ failures due to microembolism. Furthermore, postoperative hemorrhage by using low dose heparin seemed to be unrisky. Compared with the previous method, bio-pump with an interposed soft reservoir provides adequate circulation to the lower body even if acute excessive bleeding occurred.
离心泵（生物泵）在降主动脉瘤手术中作为临时分流装置，是为下半身提供充足循环的有效手段。但在急性大出血时，流向腹腔脏器和脊髓的血流量估计值存在差异。我们对2例降主动脉瘤患者在低剂量全身肝素化情况下使用了带有插入式软储液器的生物泵。在急性大出血时，两例患者均维持了充足的血流和灌注压力，且没有因微栓塞导致器官衰竭的证据。此外，使用低剂量肝素术后出血似乎没有风险。与之前的方法相比，即使发生急性大出血，带有插入式软储液器的生物泵也能为下半身提供充足的循环。
