ABSTRACT

Objective. We sought to evaluate the complications of surgical wound in patients undergoing myocardial revascularization with bilateral vs unilateral harvest of the internal mammary artery, from the population of northern Mexico. Material. A total of 178 patients were analyzed. Forty-five consecutive cases of the bilateral internal mammary artery harvested group and 133 randomized patients in the unilateral harvested group, from January 1, 2017 to September 30, 2019 at our institution. The analysis was done by means of inferential statistics of qualitative variables, comparisons of quantitative characteristics between the two groups and estimation of relative risk (RR). Results. We found 4.4% of surgical wound complications in the double internal mammary artery harvested group, 2.2% corresponding to superficial infection of the surgical, 2.2% surgical wound dehiscence. As risk factors, for women who underwent bilateral internal mammary artery grafting have a RR of 1.35 (95% CI 0.19-9.71, p = 0.043), patients with type 2 diabetes mellitus a RR of 1.22 (95% CI, 0.027-5.62, p = 0.551), and patients with BMI › 30 had a RR of 1.29 (95% CI, 0.13-12.96). Conclusions. There are no differences in the incidence of complications related to the type of surgery. Risk factors related to surgical wound complications are the female gender, type II diabetes mellitus, and overweight.
