We performed endovascular stent-graft
placement on 39 patients with abdominal aortic aneurysms between
1996 and March 2002―a period of approximately 5 years (first
half: until the end of June 1998，second half: July 1998 onward).
Three patients in the first half of the period and 8 patients
in the second half were 80 years or older. Two cases of mycotic
aneurysm were observed. During the second half, we encountered
high-risk cases in which the patients had complications such
as coronary artery disease (5 patients), COPD (1 patient) and
thoracic aortic aneurysm (4 patients). Although we had to switch
to surgery in 3 patients during the first half of the period,
we successfully placed stent-grafts in the other 36 cases (92%).
Endoleaks were observed in 6 patients, and dissection of the
iliac artery was observed in 5 patients (stents had been placed
in all patients). In 50% of all cases in the first half of the
period and 89% of all cases in the second half, stent-graft placement
was successful and no endoleak was observed. During the follow-up
period，3 cases required additional treatment, and another 4 cases
required surgery. Four patients died in hospital during the first
half of the period, and 3 patients died during the following
3 years. The 3-year survival rate was 82%. It was considered
that stent-graft placement for abdominal aortic aneurysms is
particularly effective for high-risk patients, and that the results
of this type of therapy will improve in the future.
