Abstract:
Aortic endovascular stent infection(AEI)is a rare and potentially fatal complication following endovas-cular aortic repair(EVER).Its occurrence involves multiple factors.Actively preventing the colonization and ad-hesion of pathogenic microorganisms on the stent can significantly reduce the incidence rate of AEI.The clini-cal manifestations of AEI are nonspecific.Patients who develop unexplained fever,fatigue,pain or elevated in-flammatory markers after EVER should be alerted to the possibility of AEI and require laboratory and imaging ex-aminations to be improved actively for further clarification.For patients diagnosed with AEI who can tolerate sur-gery,the preferred treatment is to thoroughly remove infected materials and tissues,and to reconstruct blood sup-ply and administer antibacterial therapy according to the patient's condition.For those who cannot tolerate surger-y,long-term or lifelong antibacterial drug therapy is required,which can be supplemented by percutaneous punc-ture drainage.Strict screening of EVER patients,active prevention of pathogen colonization,early diagnosis and multidisciplinary combination treatment can significantly reduce the incidence and fatality rate of AEI,there-by improving patient prognosis.
