[Stenting for dissecting restenosis of the subclavian artery after balloon angioplasty: a case report].
A 51-year-old male presenting with dizziness and arm claudication was admitted to our hospital. The angiogram showed severe stenosis of the left subclavian artery accompanied by to and fro motion of left vertebral artery flow. He was treated at first by percutaneous transluminal angioplasty (PTA) resulting in satisfactory dilatation of the stenosis and transient amelioration of the symptoms. However, the symptoms recurred five months later and the angiogram revealed restenosis with subintimal dissection. We chose stent implantation as the second treatment, and, hemodynamically, it produced a good result. As some reports have suggested, because of the therapeutic limitation of surgery or PTA, stenting could be a good alternative for the treatment of such disease, since it is less invasive and safe even in patients with a wide range of systemic atherosclerosis.
