Abstract
We have already experienced the many complications such as sepsis, abscess, infection etc, when the postoperative hemorrhagic effusion failed to be eliminated from thoracic or abdominal cavity through the drainage tube. the main cause of its failure is based on the occlusion of drainage tube, due to the thrombus formation. This report presented the possibility of clinical application of new polyvinyl chloride drain, on which urokinase was immobilized via Gantrez. The urokinase-treated drain had the high anithrombogenicity and followed the superior clinical results.
