Purpose:
To retrospectively review and to report the results of stent placement for focal mid-abdominal aortic stenoses.
Materials And Methods:
During a 4-year period, 10 focal mid-abdominal aortic stenoses were treated with stent placement in nine patients (six women and three men; mean age, 61 years; range, 49-73 years). All of the stenoses were atherosclerotic in nature except for one at the proximal anastomosis of an aortobi-femoral graft, which may have been from fibrointimal hyperplasia. Seven of the 10 stenoses were treated with primary stent placement, whereas three were treated with stent placement after suboptimal angioplasty.
Results:
The technical success rate was 100%. Clinical success, defined as complete elimination or improvement of symptoms present before stent placement, was achieved in eight of the nine patients with a mean duration of follow-up of 1.6 years (range, 0.2-3.0 years).
Conclusion:
In view of the excellent technical and clinical success, the authors believe that stent placement should be considered as an adjective therapy to angioplasty or as a primary method of treatment in properly selected patients with focal mid-abdominal aortic stenoses.
