Abstract
A closed system of portable cardiopulmonary bypass (PCPB) with centrifugal pump and membrane oxygenator was developed and used in 5 patients. This system was designed for femoral artery and femoral venous approach either percutaneous or open method. Successful circulatory support was performed in 3 high risk patients with coronary artery disease during PTCA and cardiopulmonary resuscitation in the other 2 patients with profound shock, one from pulmonary embolism, and the other from left ventricular rupture following acute myocardial infarction. In the supported PTCA, left main coronary stenosis was safely dilated under the PCPB support ranging in period from 58 to 160 minutes (average 93 minutes). In the other 2 patients with shock, resuscitation was performed by this system and open heart surgery was possible in both patients subsequently. PCPB was confirmed as a useful method for circulatory support in high risk PICA and cardiopulmonary resuscitation for profound shock.
