Abstract: This paper investigated the relationship between in-hospital death after endovascular repair of acute Stanford type B aortic dissection and neutrophil/lymphocyte ratio (NLR), mean platelet volume/platelet ratio (MPR), vasoactive-inotropic score (VIS). Selected 198 patients with acute Stanford type B aortic dissection, and analyzed the differences in clinical data and multi-slice spiral CT (MSCT) image characteristics between in-hospital death and non-death patients. The results showed that age, NLR, MPR, VIS score and the percentage of the false lumen area at the tracheal bifurcation to the total area aortic lumen area of dead patients were significantly higher than those in non-dead patients (P<0.05). Age, NLR, MPR, VIS score and the percentage of percentage of the false lumen area at the tracheal bifurcation to the total area aortic lumen area were the influencing factors of in-hospital death (P>0.05). The area under the ROC curve of the five combined with the prediction of hospital death was 0.801, P<0.05. NLR, MPR, VIS scores and the percentage of percentage of the false lumen area at the tracheal bifurcation to the total area aortic lumen area are significantly increased in patients who died in hospital after endovascular repair of Stanford type B aortic dissection, which has certain application value in predicting prognosis.

Key words: acute Stanford type B aortic dissection, endovascular repair, death, NLR, MPR, vasoactive-inotropic score
