Abstract：Objective To discuss the influence of multi-layer bare stent technology on blood pressure[diastolic blood pressure(DBP)and systolic blood pressure(SBP)]and safety in patients with aortic dissecting aneurism(ADA),and to investigate relative intervention therapies.Methods ADA patients(n=27)undergone treatment of multi-layer bare stent technology were chosen from the Third People's Hospital of Chengdu City from Jan.2020 to Jan.2023.The levels of DBP,SBP,diameters of true and false lumens,patency rate of branch artery and thrombosis ratio(STR)in false lumen of dissection were statistically analyzed by using SPSS 23.0 software before and after treatment.The short-term and mid-term curative effects and operative safety were comprehensively reviewed in ADA patients.Results After the operation and followed up for 3 months,the levels of 24h SBP,24h PP,24h DBP,dSBP,dDBP,nSBP and nDBP were lower,and levels of dPP and nPP were higher compared with before operation(P＜0.05)in 27 ADA patients.After the operation,partial thrombosis in dissection decreased gradually from 3,6,12 to 18 months,and complete thrombosis in dissection increased gradually from 3,6,12 to 18 months,and pair-wise comparison at the same time point showed significant difference(P＜0.05).After the operation,diameter of thoracic aorta decreased significantly,and diameter of abdominal aorta and the maximum diameter of true lumen increased significantly at 3,6,12 and 18 months(P＜0.05).The observation on postoperative complications showed that percentage of re-thoracotomy for hemostasis was 7.41%,that of transient disturbance of consciousness was 3.70%and that of hemofiltration was 7.41%.The total incidence of postoperative complications was 18.52%.Conclusion The safety,short-term and mid-term curative effects of multi-layer bare stent technology are higher in ADA treatment,which is beneficial to aortic dissection stability and branch arteries patency.The perioperative application of precise nursing mode for aortic diseases is also beneficial to reducing high expression of blood pressure and stabilizing blood pressure in ADA patients.
