    Abstract:
    OBJECTIVES: Partial upper sternotomy is a routine approach to aortic valve surgery. For surgery of the ascending aorta or the aortic arch, this method is not well established yet. METHODS: From October 2007 to October 2010, 50 consecutive patients underwent procedures of the ascending aorta and the aortic arch using partial upper sternotomy. Thirty-six patients underwent replacement or tightening of the ascending aorta, 11 patients received additional replacement of the proximal arch and in 3 cases, a complete replacement of the aortic arch was performed. Thirty-nine patients underwent additional aortic valve surgery. RESULTS: Mean operation time was 249 ± 51 min. Mean aortic cross-clamp and cardiopulmonary bypass time were 95 ± 27 and 141 ± 35 min, respectively. No conversion to conventional sternotomy was performed. All valves appeared competent on postoperative echocardiography. Survival was 100%. One re-exploration for bleeding was necessary. One stroke (2%) occurred, one pacemaker was implanted due to third-degree AV block and 16 patients (32%) experienced atrial fibrillation. One patient suffered from sternal wound infection. One patient needed reoperation due to severe aortic insufficiency on postoperative day 13. Median postoperative ventilation time was 13 h, median intensive care unit (ICU) and hospital stay were 22 h and 7 days, respectively. CONCLUSIONS: Results show that minimally invasive surgical procedures of the ascending aorta and the aortic arch may be performed safely, with an excellent clinical outcomes and superior cosmesis. Short ICU and hospital stay indicate the beneficial effects of reduced surgical trauma for patient recovery.
