New Treatment Applying Low Level Laser Therapy for Acute Dehiscence Saphenectomy in Post Myocardial Revascularization

摘要

Introduction: In Brazil, the main cause of death is the coronary heart disease and the surgical treatment applied in such cases is the Myocardial Revascularization (MR). Patients undergoing to MR through saphenous vein bypass development dehiscence in 10% of the cases. Dehiscence of surgical incision through Biomodulation treatment with Low Level Laser Therapy (LLLT) in patients who underwent to MR seems to be an unprecedented new therapy and a less invasive technique, which can benefit patients and Institutions, reducing costs. Methodology: It was analyzed 7 diabetic patients, mean age 51, 8 years old that post MR surgery presented dehiscence of the saphenectomy incision on lower limb with erithema, edema and pain. The wounds area varies from 2,2 until 34,8 cm and deep from 0,1 until 1,1 cm. It was used only Diode Laser C.W. (655 nm wavelength), Power = 25 mW, Time = 30 s, Fluence = 4 J/cm2 applied punctually around surgical wound's sore, by 2 cm distance. Results: It was observed granulated tissue all around the incision, as well as decreased inflammatory process, reduction fibrin and wound's size, besides analgesic effect since the first application. It was required in superficial wounds only 3 applications, while in the extensive wounds 8–10 applications were necessary. The LLLT has shown a remarkable role as a wound healing facilitated agent, reflecting the reduction of inflammatory process and improving analgesia. Conclusion: LLLT assisted dehiscence post saphenectomy showed a substantial improvement to the patient's quality of life, with a cost-effectiveness treatment that can benefit both patients and Institutions as an effective and less invasive therapy.
