Aim. Two-years experience related to endoluminal treatment of pseudoaneurysms and isolated iliac aneurysms are reported.
Methods. Between January 99 and December 2001, 10 male patients with a mean age of 70 years (range 60-87 years) underwent endoluminal repair for 4 primary iliac aneu-rysms, 3 pseudoaneurysms and 3 aneurysms developed after aorto-iliac bypass. The mean diameter of the treated aneurysms was 42.6 mm range 30-85 mm. Based on surgical risk the patients were classified as follows 1 patient ASA 2,7 patients ASA 3 and 2 patients ASA 4. General anesthesia was used in 3 patients whereas local anesthesia and assisted local anesthesia were used in 2 and 4 patients, respectively. The procedure was performed via surgical femoral access in 9 patients and percutaneous femoral access in 1. A total number of 11 various types of stent-grafts were implanted.
Results. The technical success of primary endograft implantation was 100%; the mean postoperative hospitalization time was 3.8 days (range 2-8 days). The mean follow-up period was 6 months (range 5-30 months). No immediate or late complications occurred. Primary stent-graft patency relating to 2 years follow-up was 100%. Mean reduction of the aneurysmal sac diameter was 4.5 mm.
Conclusion. The endovascular treatment of isolated iliac aneurysms is safe and effective and it is particularly suitable for high risk surgical patients. However, a longer follow-up and larger series are required to evaluate stent-graft patency and stability.
