BackgroundThere is insufficient evidence to guide stent usage following angioplasty in subclavian artery stenosis. This is an update of a review first published in 2011.ObjectivesThe aim of this review was to determine whether stenting is more effective than angioplasty alone for stenosis of the subclavian artery.Search MethodsFor this update the Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator searched the Specialised Register (last searched February 2014) and CENTRAL (2014, Issue 1). There was no restriction on language.Selection CriteriaRandomised controlled trials of endovascular treatment of subclavian artery lesions comparing angioplasty alone and stent implantation.Data Collection And AnalysisTwo authors independently evaluated studies to assess eligibility. Discrepancies were resolved by discussion. If there was no agreement, the third author was asked to assess the study for inclusion.Main ResultsTo date we have not identified any completed or ongoing randomised controlled trials comparing percutaneous transluminal angioplasty and stenting for subclavian artery stenosis.Authors' ConclusionsThere is currently insufficient evidence to determine whether stenting is more effective than angioplasty alone for stenosis of the subclavian artery.
