Effectiveness of Low-Intensity Laser Therapy on Tissue Repair Following Saphenectomy in Patients Who Underwent Coronary Artery Bypass Graft: A Randomized, Double-Blind Study.

Objective: To verify the effectiveness of low-intensity laser therapy (LLLT) on tissue repair following saphenectomy during postoperative period in patients having undergone coronary artery bypass graft (CABG).

Materials And Methods: A randomized clinical trial, controlled and double-blind study was conducted with 40 volunteers, divided into 2 groups: a placebo group (PG, n = 20) and a laser group (LG, n = 20). The patients in the LG group were irradiated with laser during saphenectomy (InGaAlP, λ 660 nm, energy density 6 J/cm) daily from the first to the fourth postoperative day.
