"All in one" cardiopulmonary bypass circuit for aortic surgery.
We devised an "all in one" cardiopulmonary bypass circuit for aortic surgery, and evaluated its efficacy and safety. The circuit consisted of a venous line, reservoir, single centrifugal pump, membrane oxygenator and arterial line bifurcated into two lines for systemic perfusion and selective branch perfusion. The perfusion volume was regulated by an occluder and measured by a flow sensor. A closed partial bypass was established using a shunt line bypassing the reservoir. We applied this circuit to 25 patients with aortic disease. Regulation of both the selective cerebral perfusion (SCP) and the selective branch perfusion was easily performed. There was neither stroke nor organ dysfunction postoperatively. There are some cases in which it is difficult to decide the necessity for SCP preoperatively; the use of this circuit may resolve this problem. This circuit can be easily and safely applied to any type of aortic surgery.
