目的:探讨非复杂性Stanford B型急性主动脉夹层患者采用胸主动脉腔内修复术(TEVAR)治疗后的临床效果及患者炎症应激、免疫细胞水平的变化。方法:回顾性分析2014年4月至2016年1月本院心外科收治的急性主动脉夹层患者60例，依据治疗方式不同分为保守治疗组(n n＝30)和TEVAR治疗组(n n＝30)。保守治疗组给予药物治疗，TEVAR治疗组给予胸主动脉腔内修复术治疗。检测两组患者治疗前后炎症指标及免疫细胞水平，对比分析两组患者的近期及中远期治疗效果。n 结果:治疗前两组患者血清白介素-6(IL-6)、IL-8及肿瘤坏死因子-α(TNF-α)水平比较差异无统计学意义(n P>0.05)；治疗后两组患者的IL-6、IL-8及TNF-α水平均较治疗前明显降低(n P0.05). After treatment, the levels of inflammatory cytokines in the two groups were significantly lower than those before treatment (n P<0.05); The levels of IL-6, IL-8 and TNF-α in the TEVAR group were significantly lower than those in the conservative group (n P0.05). After treatment, the number of white blood cells and neutrophils decreased significantly in the two groups; and the number of lymphocytes in the two groups was significantly increased (n P<0.05). The number of white blood cells and neutrophils in the TEVAR group was significantly lower than that in the control group, and the number of lymphocytes was significantly higher than that in the conservative group (n P<0.05). The effective rate of the TEVAR group was significantly higher than that of the conservative group (n P0.05). The 2-year survival rate of the TEVAR group was significantly higher than that of the conservative group. The postoperative complication rate was significantly lower than the conservative group (n P0.05).n Conclusions:TEVAR has a better therapeutic effect, and improve survival rate to some extent.
