Abstract:
We reviewed the results of 14 patients who underwent the operation of thoracic aneurysms using a centrifugal pump. Nine patients had atherosclerotic aneurysms and 5 had aortic dissections. The autotransfusion system (ATS) was used to keep hemodynamic stability by rapid transfusion. The ATS consisted of a roller pump, a 2, 000ml reservoir and a heat exchanger. Two mg/kg of heparin was given to the patients to keep ACT over 400 seconds. All patients survived. Body temperature increased 0.08±0.59°C during bypass with the ATS, and no patients showed hemodynamic instability after aneurysmotomy under the help of the ATS. We conclude that 1) the centrifugal pump is a useful and safe assisting means for the surgery of thoracic aneurysms, 2) the autotransfusion system has advantages as follows: keeping stable circulation and preventing loss of body temperature during bypass.
