however , 4 weeks later the vessels treated with laser thermal angioplasty had less restenosis , defined as a 20 % or greater reduction in luminal diameter ( two of nine vessels [ 22 % ] vs 10 of 10 vessels [ 100 % ] ; p less than .001 ) , and a significantly larger mean luminal diameter ( 1.6 +/- 0.5 vs 1.0 +/- 0.4 mm ) than those treated with conventional balloon angioplasty ( p less than .02 ) .
