RAMIREZ, José L et al. Influence of the use of a less invasive technique that reduces the appearance of complications of safenectomy in myocardial revascularization surgery. Rev. Col. Cardiol. [online]. 2007, vol.14, n.6, pp.389-394. ISSN 0120-5633.

Background: The internal saphenous vein, despite all its limitations, remains the most used duct for myocardial revascularization. However, the complications regarding the extraction of the vein are a big problem in terms of morbidity, length of hospital stay and costs. Material and methods: We present a controlled clinical assay, evaluating a less invasive technique for obtaining the saphenous vein in comparison with the standard technique previously used in our institution. For this purpose, we took 200 patients who underwent surgery and 400 patients in the control group. Results: in hospital saphenectomy infection rate was 0.5% compared to 4% in the control group, resulting a RR=0.125 value with a confidence interval of 95% of 0.016 – 0.916 significantly smaller in the study group: the RRA value was 3.5% and the NNT was 28 which means that with this technique one case of infection is avoided in every 28 patients who undergo surgery. Furthermore, we found that patients who underwent surgery have significant less hospital stay than those in the control group. Mean stay was 7.39 ± 5.8 days for the intervened group and 8.64 ± 8.55 days in the control group. Conclusions: We can conclude that the less invasive saphenectomy technique is safe, easy to learn and offers a great advantage in regard to the morbidity associated to the surgical wound of the legs in coronary artery bypass surgery.
