CLINICAL EXPERIENCE WITH LEFT HEART BYPASS WITHOUT SYSTEMIC HEPARINIZATION FOR THORACIC ANEURYSMS

Experience with 7 patients undergoing graft replacement of a thoracic aortic aneurysm by means of Bio-Pump and Heparinized Hydrophilic Polymer (H-PSD) tube is presented. During aortic cross-clamp (46-165min, average 87min), hemodynamics were stable and the maximum bypass flow of the Bio-Pump average...

Summary:Experience with 7 patients undergoing graft replacement of a thoracic aortic aneurysm by means of Bio-Pump and Heparinized Hydrophilic Polymer (H-PSD) tube is presented. During aortic cross-clamp (46-165min, average 87min), hemodynamics were stable and the maximum bypass flow of the Bio-Pump averaged 2.0±0.4L/min. A considerable reduction in the operative blood loss could be achieved. Thrombo-embolic complication was not recognized. Platelet counts, blood coagulation test (PT, APTT), and hepato-renal function immediately after operation were satisfactory. We believe that the nonthrombogenic left heart bypass provides the safest available technique for prolonged cross-clamping of the thoracic aorta.
