We reviewed the effect of obesity in the repair of type A acute aortic dissection (AAD). Between January, 2009 and June, 2010, repair of type A AAD was performed in 51 patients. We divided these patients into 2 groups according to body mass index( BMI). Twenty-two patients whose BMI was≥25 were classified as group O, and 29 patients whose BMI was<25 were classified as group N. The mean age of group O was younger than that in group N(60.2±11.9 versus 68.3±10.2 years, p=0.01). The incidence of postoperative hypoxemia was greater in group O than that in group N(81.8% versus 53.6 %, p=0.036). The intubation period was longer in group O than that in group N(8.0±7.1 days versus 3.7±3.1 days, p=0.014), and the intensive care unit (ICU) stay was longer in group O than that in group N(13.7±8.8 days versus 9.3±5.9 days, p=0.04). Obesity is thought to be a risk of young-onset of AAD and postoperative hypoxemia, as well as a prolonged intubation period and ICU stay.
我们回顾了肥胖对A型急性主动脉夹层（AAD）修复的影响。在2009年1月至2010年6月期间，对51例患者进行了A型AAD修复术。我们根据体重指数（BMI）将这些患者分为两组。BMI≥25的22例患者被归类为O组，BMI<25的29例患者被归类为N组。O组的平均年龄低于N组（60.2±11.9岁对68.3±10.2岁，p = 0.01）。O组术后低氧血症的发生率高于N组（81.8%对53.6%，p = 0.036）。O组的插管期长于N组（8.0±7.1天对3.7±3.1天，p = 0.014），O组在重症监护病房（ICU）的停留时间长于N组（13.7±8.8天对9.3±5.9天，p = 0.04）。肥胖被认为是AAD年轻发病、术后低氧血症的危险因素，也是插管期延长和ICU停留时间延长的危险因素。
