  • Title: Supra-aortic arterial stenoses: management with Palmaz balloon-expandable intraluminal stents.
    Author: Lyon RD, Shonnard KM, McCarter DL, Hammond SL, Ferguson D, Rholl KS.
    Journal: J Vasc Interv Radiol; 1996; 7(6):825-35. PubMed ID: 8951749.
    Abstract:
    PURPOSE: The authors report on the use of Palmaz balloon-expandable intraluminal metallic stents to supplement conventional balloon angioplasty and to primarily treat a variety of supra-aortic arterial atherosclerotic lesions manifested by claudication or embolic phenomena. PATIENTS AND METHODS: Results from a series of seven patients are reported. Five patients received stents following percutaneous balloon angioplasty (PTA): four patients received five stents for suboptimal initial result of PTA and one patient received one stent for early restenosis following successful PTA. Two patients received three stents primarily: one patient had one stent placed for a highly eccentric innominate lesion and the other patient had two stents placed for an ulcerated nonocclusive subclavian lesion causing blue digits. RESULTS: Treatment produced immediate angiographic or hemodynamic improvement in all seven patients. Clinical follow-up was obtained on all patients (mean, 10 months; range, 3-18 months). One patient had an episode of vertigo after PTA of a right subclavian lesion that resolved after thrombolytic therapy and stent placement. CONCLUSION: The placement of metallic stents in supra-aortic arteries represented an effective adjunct to PTA of atherosclerotic stenoses in these vessels. Primary stent placement may be an effective treatment for selected lesions.
