Polytetrafluoroethylene (PTFE) grafts, 1 mm in internal diameter, were interpositioned in the infrarenal aortas of 20 adult Sprague‐Dawley rats with either continuous or interrupted sutures. The interrupted‐suture (I‐S) technique was used in ten rats, the continuous‐suture (C‐S) technique in the other ten. After followup of 90 days, the overall patency rate for the 20 rats was 95% (19/20); all grafts in the C‐S group were patent; one graft in the I‐S group had occluded on the day of operation. Since excellent patency rates were obtainable with these minute PTFE grafts placed in the rat aorta by either technique, the speed with which the C‐S technique can be accomplished appears to make it preferable.
