A CLINICAL USE OF A NEW WOVEN VELOUR DA CRON VASCULAR PROSTHESES (VELEX^TM)

-AS COMPARED WITH A KNITTED VELOUR DACRON VASCULAR PROSTHESES (USCI SAUVAGE^TM BIONIT II)-

Abstract

We used a new woven velour Dacron vascular prostheses (Velex^TM) in ten cases of replacement of abdominal aortic aneurysm. As compared with a knitted velour Dacron vascular prostheses (USCI Sauvage^TM Bionit II) used in thirty cases of the same operation, the handling of Velex^TM was as easy as that of Sauvage^TM. The intra-operative blood loss of Velex^TM group was significantly lesser than that of Sauvage^TM group (382±185gm vs. 760±326gm, p=0.048). And the operation time was significantly shorter in Velex^TM group than that in Sauvagegroup (151±33 min. vs. 215±38min., p=0.012). There was no complication caused by prostheses in each groups in early post operative period. So it is concluded that the usage of Velex^TM vascular prostheses may decrease the intraoperative blood loss, and may shorten the operation time during replacement of abdominal aortic aneurysm compared to Sauvage^TM vascular prostheses.
