Study Comparing Coronary Stenting in Smaller Vessels Versus Large Vessels

Angiographic and clinical outcome following coronary stenting of small vessels: a comparison with coronary stenting of large vessels.

OBJECTIVES Stent implantation reduces restenosis in vessels > or =3 mm compared with balloon angioplasty, but few data are available for stents implanted in vessels <3 mm. The aim of this study was to evaluate immediate and follow-up patient outcomes after stent implantation in vessels <3 mm compared to stent implantation in vessels > or =3 mm. METHODS Between March 1993 and May 1996, a total...

The smaller intracerebral vessels.

The Smaller Intracerebral Vessels • A pathological study of the smaller intracerebral arteries of 150 to 600 /A was made in 336 cases, ranging in age from 1 day to 96 years. The changes involved the media and adventitia in contradistinction to the large cerebral vessels which showed predominantly intimal changes. The degree of change in the smaller intracerebral arteries was age related but not...

Coronary microvasculature: small vessels with large impact.

Coronary stenting versus balloon angioplasty in small vessels: a meta-analysis from 11 randomized studies.

OBJECTIVES A meta-analysis of 11 randomized trials was done to compare stenting versus balloon angioplasty (BA) in small coronary vessels. BACKGROUND Randomized studies on coronary stenting (CS) in small vessels have yielded controversial results. METHODS Eleven randomized trials on CS versus BA in small vessels, including angiographic re-evaluation at six months, were analyzed. RESULTS T...

Stenting for small coronary vessels: a contestable winner.

Stents were initially used to manage or prevent acute vessel closure after percutaneous transluminal coronary angioplasty (PTCA). The first direct randomized comparison with respect to restenosis showed the superiority of stenting to PTCA for de novo lesions situated in native vessels 3 mm or larger (1,2). In these trials, stenting was associated with a 25% to 30% reduction of restenosis as com...
