Objective: To know the prevalence and risk factors for complications of saphenous vein harvesting for myocardial revascularization in patients operated at the Department of Cardiothoracic Surgery. Design: Prospective, cross-sectional, descriptive, and comparative study. Statistical analysis: Central tendency measures and Student's t test. Patients and methods: We studied patients subjected to myocardial revascularization between January 1st and October 31st 2011, in whom the saphenous vein was harvested to be used as free graft, with or without using additionally the left internal mamary artery. The graft was obtained through multiple incisions. Hematoma, infection, edema, suture material rejection, dehiscence, necrosis, cellulitis, dermatitis, thrombosis, seroma, compartmental syndrome were considered complications. We compared the number of incisions, length of incisions, inverse saphenous vein obtainment, surgical time and aorta clamping between complicated and non-complicated patients. Results: In the studied period, 150 patients (129 men and 21 women) were subjected to saphenous vein harvesting to be used as a free graft. Average age was of 61 ± 9.48 years. Prevalence of complications was of 29%, corresponding 19% (n = 29) to hematoma, 4.6% (n = 7) to infection of the surgical site, 2% (n = 3) to edema, 1.3% (n = 2) to reaction of the suture material, and 2% (n = 3) to dehiscence. No statistical difference was found in the variables between complicated and non-complicated patients. Conclusions: Prevalence of complications in saphenous vein harvesting for myocardial revascularization was low, and was within the ranges accepted in the medical literature. We did not identify risk factors.
