Bilateral pectoralis advancement flaps and transverse plate fixation system for sternal reconstruction in the complicated sternal wound

Methods Between 2008 and 2012, 24 patients with a complicated sternal wound underwent a sternal reconstruction with bilateral pectoralis advancement flaps and a transverse plate fixation system. The median age of the cohort (4 female and 20 males), was 65.8 years (range: 33-83 years). In 19 patients, a bilateral internal thoracic artery had been used. Considerable preoperative risk factors were present: morbid obesity with Body Mass Index (BMI) ≥ 35 (range: 35 – 49.7: 13 patients); chronic obstructive pulmonary disease (COPD) without steroid therapy preoperatively (7 patients); diabetes mellitus (7 patients). Concomitant laparoscopically harvested omentoplasty was performed in case of overt mediastinits (4 patients). In 14 cases, the mediastinal wound was prepared with negative pressure wound therapy following surgical debridement. An internal fixation of the sternum by titanium locking plates with sternal and rib-to-rib fixation and bilateral pectoralis advancement flaps were performed in all patients. The postoperative course of was followed by clinical follow-up. Results Early postoperative sternal stability was seen in all 24 patients. The 30-day perioperative mortality rate was zero, with an overall survival of 100% until today. Postoperatively 2 (8.3%) small superficial and 1 (4.1%) deep surgical site infection (SSI) were appreciated. Follow-up ranged from 6.5 to 54.5 months (median: 26.5 months).
