| Abstract |
|
1)Among the 24 involved vessels, 5 renal arteries and one left suclavian artery were occulded totally and they were not candidate for angioplasty.
2)Four brachiocepholic branches, three renal artery, and two abdominal aorta were short segmental narrowing in nature and they were feasible for balloon dilatation,
3)Eight sites of thoracic or abdominal aorta in 5 patients were involved in diffuse long segment and they were more resistant to balloon angioplasty compraing with short segmental lesions.
4)Three patients (4 arteries) needed angioplasty again because of the restenosis at the previous sites on the angiographic re-evaluation 1 or 2 year later. They all showed the persistent inflammatory process with elevated ESR(<20) and positive CRP.
5) The remaining three patients showed no evidence of restenosis with low ESR(<20) and negative CRP.
6) Four carotid artery involvements needed gradual dilatation with increasing the size of the balloon and there were no episodes of brain embolism. |
