Abstract
Nineteen canine carotid arteries were replaced with teflon mesh reinforced vein grafts. Twenty-six per cent were found, by arteriography, to be occluded at the end of 5 weeks. The rest were followed from 5 weeks to 6 months and all remained patent. This method was used in 5 patients for the replacement of diseased carotid artery segments. One of these thrombosed and 4 have remained patent. In 2 additional cases, a covering of 9 mm crimped teflon tubes, containing multiple 1.5 mm perforations, was used, instead of the mesh, to provide added resistance to compression. One of these thrombosed and the other remained patent.
