A study was designed to compare platelet deposition between knitted and woven Dacron grafts in the same patient. Twenty patients received aortoiliac or aortofemoral bifurcated Dacron grafts, each composed of one woven and one double-velour knitted limb. External nuclear graft imaging was carried out after injection of autologous platelets labeled with indium 111. The patients were studied postoperatively in time periods ranging from 6 days to 42 months. Platelet accumulation was almost identical in knitted and woven limbs in all patients. This study appears to indicate that there is no difference in thrombogenicity between knitted and woven bifurcated Dacron grafts in the aortoiliac or aortofemoral positions measured by platelet accumulation.

To investigate the difference in patency rate between woven and knitted aortofemoral or aortoiliac prosthetic grafts, a special vascular prosthesis was manufactured with one limb of the graft knitted and the other, woven. The prosthesis was implanted in 143 consecutive patients with occlusive aortoiliac arteriosclerotic disease or aneurysms. Detailed statistical analysis failed to reveal any difference in the patency rate between the woven and knitted limbs of the grafts during an observation period ranging from one month to two years.
