Aim: To evaluate the importance of long-term follow-up of patients after stent graft implantation for abdominal aortic aneurysm in terms of the incidence of late complications. Methods: From 1996 to 2021, 649 patients with aneurysms of the abdominal aorta and iliac arteries were treated endovascularly at our institution. Sixty-nine patients were followed ten or more years after stent graft implantation, 61 men and 8 women aged 50 to 81 years, the average age was 67 years. Patients were followed up with CT angiography and an X-ray of the stent graft skeleton at one-year intervals. Follow-up duration was 10-22 years, mean follow-up was 14 years, median was 13 years. Results: During follow-up in a group of 69 patients, 29 complications (42%) were detected in 22 patients (31%), which were indicated for treatment. In 8 (11.5%) patients type II endoleak without enlargement of the aneurysm sac were diagnosed, i.e. without indication for therapy. Twenty-nine late complications occurred in 1 to 18 years after stent graft implantation, 6 in less than 5 years, 12 complications in 5-10 years. Eleven complications in more than 10 years (18%), of which 9 complications in 7 patients who had no complications in the first 5 years and reduced or stationary sac aneurysm. One patient had stent graft migration, 4 patients had migration and Ia endoleak, 3 had Ib endoleak, 8 patients had type III endoleak, 3 had type II endoleak with aneurysm sac growth, 5 had endotension, and two patients had iliac limb thrombosis, stent graft thrombosis in one, and abscess in the retroperitoneum in 2 patients. Most complications were indicated for endovascular treatment. Conclusion: Late complications after stent graft implantation for abdominal aortic aneurysm at risk of aortic rupture can occur at any time during follow-up, even in patients who had no complication in the first five years after implantation and even had a reduced aneurysm sac. Long-term follow-up of patients after endovascular treatment of abdominal aortic aneurysm is therefore essential, and patients cannot be excluded from follow-up. [ABSTRACT FROM AUTHOR]
