1 Indium 111—labeled platelet deposition in woven and knitted Dacron bifurcated aortic grafts with the same patient as a clinical model  Francis Robicsek, M.D., Gordon D. Duncan, Ph.D., Carl E. Anderson, M.D., Harry K. Daugherty, M.D., Joseph W. Cook, M.D., Jay G. Selle, M.D., Philip J. Hess, M.D., Edward J. Easton, M.D., John N. Burtoft, P.A.-C.  Journal of Vascular Surgery  Volume 5, Issue 6, Pages (June 1987) DOI: / (87) Copyright © 1987 Society for Vascular Surgery and North American Chapter, International Society for Cardiovascular Surgery Terms and Conditions

2 Fig. 1 Two types of “half-and-half” aortic bifurcation grafts, one with a woven Dacron body, one limb woven, the other knitted (A); the other graft has a knitted Dacron body, one limb knitted, the other woven (B).

3 Fig. 2 Emission computed tomography scan of 111I-labeled platelet adherence with a counting time of 20 minutes with coronal cuts. There appears to be no difference between the two graft limbs.

4 Fig. 3 Representative 111I plate scan shows equal uptake over graft area. In the two encircled areas counts are compared between the woven and knitted graft limbs. MAX = maximum number of counts per pixel; MIN = minimum number of counts per pixel; TOT = total number of counts per side; PNT = total number of pixels counted; AVG = average number of counts per pixel; %SR = percent uptake ratio on each side; and BKG = background.

5 Fig. 4 Indium 111 total counts by patient groups according to postoperative time periods and by the type of graft limb material. Group I (early) shows the highest uptake. There is no significant difference between the woven and knitted limbs in any given time period.

6 Fig. 5 Indium 111 counts obtained over the graft areas expressed as a percentage of total counts. The time axis is broken to accommodate the large postoperative time differences. Each vertical line represents an individual patient with the position of the circles indicating the percentage of the 111I-labeled platelet uptake by the woven and by the knitted limbs, respectively. Overlapping circles indicate identical uptake by both limbs.
