| Popis: | Purpose This report describes the early clinical experience with use of a transluminally placed endovascular graft (TPEG) covered with pre-expanded polytetrafluoroethylene (PTFE) to treat iliac artery aneurysms and fistulas. Materials and Methods Eight patients with iliac artery aneurysms ( n = 7) and common iliac artery to common iliac vein fistula ( n = 1) were treated with TPEGs. The iliac artery aneurysms were either common iliac ( n = 6) or hypogastric ( n = 1). All of the patients had significant comorbid diseases. The TPEG devices were made with pre-expanded PTFE sutured to Palmaz stents and delivered through 10- or 12-F sheaths. Results The aneurysms were successfully excluded in six of seven patients and the one iliac artery-to-vein fistula was successfully occluded. There were no immediate procedural complications related to the TPEG devices. Follow-up was limited (mean, 12 months), but no stenoses or occlusions of the TPEG devices were detected. The one failure was probably due to the marked tortu-ousity of the iliac artery, which prevented an adequate seal. Conclusion In the authors' early clinical experience, the use of TPEG devices with pre-expanded PTFE successfully treated iliac artery aneurysms and an iliac artery-to-vein fistula. Although the results are encouraging, longer follow-up is necessary to better evaluate this type of treatment. |
