Abstract
A knitted Dacron velour externally supported prothesis was broken in two pieces at the supported portion 3 years after femoroposterior tibial bypass grafting. This type of graft problem has never been reported. Details of the clinical course, angiogram, CT scan, and scanning electron micrograph of a portion of the graft are shown. The externally supported Dacron prosthesis broke into two pieces along the broken coil of the middle portion. A possible cause of this failure may have been due to damage of the Dacron fibers in the process of heat fusing the coil. This presentation emphasizes the possibility of this rare externally supported graft complication, and the necessity for careful follow-up not only of the graft patency but also for the mechanical defects of the implanted externally supported Dacron graft itself.
