 Although carotid endarterectomy is typically preferred over carotid artery stenting, stenting is indicated in select patients with radiation-induced stenosis or a carotid lesion not suitable for surgery.Angioplasty is used to treat venous stenosis affecting hemodialysis access, with drug-coated balloon angioplasty proving to have better 6 month and 12 month patency than conventional balloon angioplasty.Angioplasty is occasionally used to treat residual subclavian vein stenosis following thoracic outlet decompression surgery for thoracic outlet syndrome.
