Abstract:
Objective To compare the curative effect of thoracic endovascular repair (TEVAR) plus medication with that of pure medication in treating uncomplicated type B aortic dissection,and to discuss the treatment strategy for uncomplicated type B aortic dissection.Methods The clinical data of 118 patients with definitely confirmed uncomplicated type B aortic dissection,who were admitted to authors' hospital during the period from 2004 to 2015,were retrospectively analyzed.Among the 118 patients,57 patients received TEVAR plus medication (TEVAR group) and 61 patients were treated with pure medication (drug group).The complications and mortality within one month and during follow-up period in both groups were calculated respectively,and Kaplan-Meier survival curves were used to compare the survival rate between the two groups.Results The incidences of complications and morbidity during hospitalization and within one month after treatment in TEVAR group were 5.2％ and 0％ respectively,which in the drug group were 0％ and 0％ respectively.The patients were followed up for 1-110 months,with a mean of (43.3±36.7) months.The incidence of main complications and the mortality in TEVAR group were 7.0％ and 5.3％ respectively,which in the drug group were 6.6％ and 8.1％ respectively.The one-,2-,4-and 7-year cumulative survival rates in TEVAR group were 100％,97.1％,93.5％ and 78.0％ respectively,which in the drug group were 98.4％,96.4％,90.8％ and 72.7％ respectively,the differences between the two groups were not statistically significant (~=0.019,P=0.890).Conclusion For the treatment of uncomplicated type B aortic dissection,TEVAR plus medication is superior to pure drug therapy in reducing expansion rate of false cavity,but TEVAR carries some procedure-related complications,besides,TEVAR can not improve the survival rate.(J Intervent Radiol,2017,26:266-269)
