Objective:
To assess the initial results of insertion of a new woven Dacron graft coated with a polymer for occlusive and aneurysmal aortoiliac disease.
Design:
Open study.
Setting:
Four Swedish vascular surgical units.
Subjects:
28 patients who required aortoiliac or aortofemoral reconstruction between September 1988 and June 1989.
Main Outcome Measures:
Incidence of, and time to, occlusion; type of intervention; whether the graft needed to be replaced; and mortality.
Results:
Two patients died in the postoperative period, and five during follow-up, giving an overall mortality of 25%. None of the tube grafts occluded but 17 of 24 bifurcation grafts did (71%), the median time to occlusion being 126 days (range 10-820). Our results have led to this graft being removed from the market while modifications are made in the process of impregnation of polymer.
Conclusions:
Strict protocols for the assessment of new graft materials should be introduced and enforced.
