However, the implications of AKI before thoracic endovascular aneurysm repair （TEVAR） of type B acute aortic dissection （AAD） remain unclear. This study evaluated the incidence, predictors, and in-hospital outcomes of AKI before TEVAR in patients with type B AAD. Methods Between 2009 and 2013, 76 patients were retrospectively evaluated who received TEVAR for type B AAD within 36 h from symptom onset. The patients were classified into no-AKI vs. AKI groups, and the severity of AKI was further staged according to kidney disease： im- proving global outcomes criteria before TEVAR. Results The incidence of preoperative AKI was 36.8%. In-hospital complications was significantly higher in patients with preoperative AKI compared with no-AKI （50.0% vs. 4.2%, respectively; P 〈 0.001）, including acute renal failure （21.4% vs. O, respectively; P 〈 0.001）, and they increased with severity of AKI （P 〈 0.001）. The maximum levels of body tem- perature and white blood cell count were significantly related to maximum serum creatinine level before TEVAR. Multivariate analysis showed that systolic blood pressure on admission （OR： 1.023; 95% CI： 1.003-1.044; P ： 0.0238） and bilateral renal artery involvement （OR： 19.076; 95% CI： 1.914 190.164; P = 0.0120） were strong predictors of preoperative AKI. Conclusions Preoperative AKI frequently occurred in patients with type B AAD, and correlated with higher in-hospital complications and enhanced inflammatory reaction. Systolic blood pressure on admission and bilateral renal artery involvement were major risk factors for AKI before TEVAR.展开更多

Veno-venous (VV) extracorporeal membrane oxygenation (ECMO) is reported as one of the treatments for this life-threatening complication. A 78-year-old male patient was admitted to our hospital for Stanford type A acute aortic dissection. He underwent emergency replacement of the ascending aorta, after which he developed acute lung injury. It was difficult to maintain oxygenation with a respirator mask. Therefore, VV-ECMO was initiated on postoperative day 1. The oxygenation gradually improved, and VV-ECMO was continued until postoperative day 13. On postoperative day 25, mechanical ventilation was withdrawn. The patient was discharged from the hospital on postoperative day 149. We report a case of successful treatment of acute lung injury with VV-ECMO initiated after surgery for aortic dissection. VV-ECMO can be considered as a treatment option for severe acute lung injury after surgery for aortic dissection.展开更多

文摘目的:探讨急性Stanford A型主动脉夹层围术期急性肺损伤(ALI)的发生与D-二聚体(DD)的相关性。方法:2011年6月至2012年5月,连续收治59例急性主动脉夹层患者,均行全弓置换+支架象鼻手术。根据围术期发生ALI的情况分组:a组(10例):术前、术后均发生ALI;b组(17例):术前未发生ALI,但术后发生ALI;c组(32例):术前术后均未发生ALI。各组间结果比较采用方差分析,各因素与氧合指数的相关性采用多元线性回归分析。结果:三组术前DD比较:a组与b组、a组与c组P<0.05;b组与c组均P>0.05。术后24 h、48 h DD比较:a组与c组、b组与c组均P<0.05,a组与b组P>0.05。多元线性回归分析DD升高水平与PaO2/FiO2呈负相关性(γ=-0.032,P<0.001)。三组术后呼吸机使用时间和ICU停留时间比较:a组与c组、b组与c组均P<0.05;a组与b组P>0.05。术后有3例患者死亡,2例术后二次开胸探查,6例术后存在并发症,此11例术后均为ALI患者。结论:急性夹层围术期发生ALI的患者,有一个高的DD水平,且DD与PaO2/FiO2呈负相关性;术后发生ALI的患者,呼吸机使用时间与ICU停留时间显著延长。
文摘目的探讨急性主动脉夹层围术期急性肺损伤(ALI)的发生与循环血中血管紧张素Ⅱ(AngⅡ)的相关性。方法纳入急性主动脉夹层并行急诊手术治疗患者109例(其中Standford A型23例,Standford B型86例)。根据围术期发生ALI的情况分组:a组(13例)术前、术后均发生ALI;b组(25例)术前未发生ALI,但术后发生ALI;c组(71例)术前术后均未发生ALI。各组结果组比较采用方差分析方法,AngⅡ与氧合指数(PaO2/FiO2)相关性采用Pearson相关分析。结果术前三组AngⅡ水平比较差异有统计学意义(F=29.03,P<0.01),a组与b组和c组比较差异有统计学意义(均P<0.05);b组与c组比较差异无统计学意义(P>0.05)。三组术后24、48 h AngⅡ浓度比较,差异均有统计学意义(P<0.05);组间两两比较:a组与c组、b组与c组差异有统计学意义(P<0.05),a组与b组差异无统计学意义(P>0.05)。三组患者术后呼吸机使用时间和ICU停留时间比较:a组与c组、b组与c组均差异有统计学意义(P<0.05);a组与b组差异无统计学意义(P>0.05)。AngⅡ与氧合指数(PaO2/FiO2)呈负相关(r=-0.602,P<0.05)。术后有3例患者死亡,2例二次开胸探查,6例存在其他系统严重并发症。此11例患者术后均合并ALI。结论急性夹层围术期合并ALI的患者,循环血中均有一个较高的AngⅡ水平,而且AngⅡ与PaO2/FiO2呈负相关性;术后发生ALI的患者,呼吸机使用时间与ICU停留时间显著延长。
