“Half and Half” Woven and Knitted Dacron Grafts in the Aortoiliac and Aortofemoral Positions: Seven and One-Half Years Follow-Up

One-hundred fifty-eight patients received specially manufactured aortoiliac or aortofemoral bifurcated grafts with one limb woven, the other knitted from Dacron. During an observation period ranging from 1,567 to 2,555 days (average 2,130 days) no statistically significant difference was found in either platelet adherence (30 patients studied) or in clinical patency. According to the results of the study, the type of graft (woven or knitted) did not seem to influence either platelet adherence or patency rate in the aortoiliac or aortofemoral positions.
