Abstract

New complications are resulting from percutaneous transluminal angioplasty (PTA) and stent deployment. A 43-year-old female, admitted with weakness in the right arm, was diagnosed with right subclavian stenosis. Following PTA and a Palmaz stent deployment, her condition worsened, and symptoms spread. A corrective surgical procedure found the Palmaz stent to be almost completely compressed. The stent and plaques were carefully extracted. The etiology of compressed stent was probably due to an insufficient radial force or Hoop strength of stent. If an occlusion of the subclavian artery occurs at the segment proximal to the orifices of vertebral artery and internal mammary artery, a vertebral-subclavian steal syndrome may occur. This can be diagnosed in patients manifesting symptoms that include vertebral-basilar arterial insufficiency and a difference in brachial systolic blood pressure of at least 30 mm Hg between the two arms, with a bruit at the base of the neck or in the supraclavicular area.
