ABSTRACT
@#Objective    To investigate the effect of optimized arterial perfusion strategy on total arch replacement for acute type A aortic dissection (AAAD) with malperfusion syndrome (MPS). Methods    From 2017 to 2019, 51 patients with AAAD and MPS who had received total arch replacement with optimized arterial perfusion strategy in our hospital were included in the optimized perfusion group, including 40 males and 11 females, with an average age of 47.43±13.39 years. A total of 40 patients with AAAD and MPS who had been treated with traditional Sun's surgery were taken as the traditional control group, including 31 males and 9 females, with an average age of 50.66±12.05 years. The perioperative clinical data of the two groups were compared. Results    The preoperative baseline data of the two groups were basically consistent (P>0.05). The comparison of operative data between the optimized perfusion group and the traditional control group showed that in the optimized perfusion group, the extracorporeal circulation time, aortic occlusion time, and circulation-out cerebral perfusion time were significantly less than those in the traditional control group (223.64±65.13 min  vs. 266.77±87.04 min, 114.48±27.28 min vs. 138.20±39.89 min, 8.28±3.81 min vs. 50.53±23.60 min, all P≤0.05). The lowest intraoperative nasopharyngeal temperature in the optimized perfusion group was significantly higher than that in the traditional control group (27.10±1.18℃ vs. 23.6±3.30℃, P=0.000). Postoperative wakefulness time of the optimized perfusion group was earlier than that of the traditional control group (4.50±1.35 h vs. 5.27±1.15 h, P=0.019). The volume of blood transfusions in the optimized perfusion group was significantly less than that in the traditional control group (13.25±9.06 U vs. 16.95±7.53 U, P=0.046). There was no significant difference in ICU time and invasive ventilation time between the two groups (P>0.05). Postoperative complications of the two groups showed that the incidence of postoperative continuous renal replacement therapy in the optimized perfusion group was significantly lower than that in the traditional control group, with a statistically significant difference (21.6% vs. 42.5% P=0.003). The incidence of postoperative delirium, coma, low cardiac row syndrome and limb ischemia in the optimized perfusion group was lower than that in the traditional control group, but the difference was not statistically significant (P>0.05). The incidence of postoperative hemiplegia, sepsis, and secondary thoracotomy in the optimized perfusion group was higher than that in the traditional control group, and the difference was not statistically significant (P>0.05). Postoperative mortality in the optimized perfusion group was significantly lower than that in the traditional control group (13.7% vs. 27.5%), but the difference was not statistically significant (P=0.102). Conclusion    Optimized arterial perfusion strategy and its related comprehensive surgical technique reduce surgical trauma, shorten the operation time, reduce perioperative consumption of blood products. Postoperative wakefulness is rapid and the incidence of complications of nervous system, kidney and limb ischemia is low. Optimized arterial perfusion strategy is suitable for operation of AAAD with MPS by inhibiting the related potential death risk factors to reduce operation mortality.
