RESUMO

After cardiac surgery, healing can be delayed by sternal wound infection, particularly if mediastinitis develops. Because of the technical simplicity of omentopexy, we recommend the use during open-heart surgery of an omental pedicle graft in selected cases to prevent postoperative complications. This article describes our experience over a 4-month period (from 30 March 1989 through 2 August 1989) with this technique in 50 consecutive patients at moderate-to-high risk for postoperative sternal and mediastinal problems. The patients included 39 men (78%) and 11 women (22%), whose ages ranged from 22 to 83 years (mean, 55 years). Preoperative risk factors included extreme obesity, 13 patients (26%); chronic obstructive pulmonary disease, 13 patients (26%); diabetes mellitus, 6 patients (12%); obesity and diabetes, 8 patients (16%); and obesity, diabetes, and chronic obstructive pulmonary disease, 3 patients (6%). Operative risk factors included cardiac reoperation involving prolonged surgery, 6 patients (12%); bilateral mammary grafting, 17 patients (34%); and the need for prolonged (greater than 72-hour) mechanical respiratory assistance, 2 patients (4%). Three of the 50 patients (6%) were considered to be at moderate risk due to an increase in nosocomial infections at the time of their surgical procedures.
