A New Temporary Tube in Aortic Surgery

An application of Heparinized Hydrophilic Polymer(H-PSD)

Abstract

As previously reported, H-PSD polymer shows excellent antithrombogenecity due to the continuous release of heparin from its surface into blood stream for a longer period.
In this study, an application of the H-PSD polymer to bypass tubes was investigated in the animal and clinical experiments. 3 cases (1 dissecting aneurysm, 2 coarctation of the aorta) was operated on using this bypass tubes. It was found that during and after the bypass the hematologic parameters remained in the normal levels and SEM studies showed no thrombus formation. This H-PSD polymer seems a promising material for the temporary bypass tubes in aortic surgery.
