Purpose : To evaluate the effectiveness of treatment of aortic aneurysm with endoluminal stent-grafts using Gianturco stent and poly-tetra-fluoro ethylene (PTFE). Materials and Methods : In ten patients with aortic aneurysm, eleven procedures were performed using tubular (n=7) or bifurcated (n=4) Gianturco Z-stents covered with PTFE to treat aortic disease (six atherosclerotic aortic aneurysms, four pseudoaneurysms of abdominal aorta in three patients with Behcet's disease, and one penetrating atherosclerotic ulcer). Spiral CT angiography was used for follow-up from 14 days to 31 months (mean, 12 months). The effectiveness of stent-grafts was evaluated during follow-up. Results : In all cases, implantation of stent-grafts was technically successful ; in five, perigraft leakage was detected on completion of aortography. On initial post-procedural CT images obtained 4 - 24 days after insertion of the stent-graft, complete thrombosis of the aneurysm was seen in seven cases and perigraft leakage in four. Two of the four cases in which leakage was seen on initial CT improved spontaneously during follow-up. Procedure-related thromboembolism occurred in one case, which was managed by thrombolytic therapy without residual sequelae. During follow-up CT, the size of aortic aneurysms of atherosclerotic disease did not change. The pseudoaneurysms of Behcet's disease decreased and eventually completely disappeared, with only residual periaortic soft tissue. Conclusion : For the treatment of aortie diseases, stent grafting using a Gianturco stent and PTFE is clinically feasible, safe, and effective.
