We also report our experience with transluminal angioplasty (PTA) to restore patency to stenotic subclavian veins. The information indicates that subclavian vein stenosis occurs frequently in hemodialysis patients and is amenable to PTA. Subclavian artery stenosis is an uncommon vascular disease, showing a 4-fold left, rather than right-sided predisposition.
