Failure of ultralightweight knitted Dacron grafts in arterial reconstruction

• We have observed 11 cases in which the use of the ultralightweight knitted Dacron arterial graft made by the United States Catheter and Instrument Co. (USCI) was complicated by interstitial hemorrhage, dilation, or both. Although the incidence and specific cause of failure of this graft are unknown, we have discontinued its use on the basis of this experience. ( Arch Surg 111:146-149, 1976)
