Impact of intravascular ultrasound for the treatment of calcified infrarenal aortic stenosis: A case report study

We report two cases of heavily calcified infrarenal aortic stenosis that were successfully treated by Intravascular ultrasound‐ (IVUS)‐guided stenting. Two middle‐aged women visited our hospital due to intermittent claudication. Diagnostic arteriography revealed possible infrarenal aortic stenosis even though the findings were equivocal. IVUS demonstrated heavily calcified atherosclerotic lesions and allowed the accurate assessment of the types and extents of the lesions to be treated in both cases. The patients successfully underwent stent implantation according to the findings of IVUS. IVUS significantly contributed to the interventional successes. © 2008 Wiley‐Liss, Inc.
