Objective:To compare the early result of endovascular repair and conventional openrepair for abdominal aortic aneurysm.Methods:We analyzed the clinical data of 37 patients withinfrarenal AAA.Among them

14 patients were treated with endovascular repair(EVR group)

23 with conventional open repair(COR group).Pre-operative status

intra-operative variables

complication?mortality rate?hospital expenditure?post-operative outcomes and laboratory findings of the two groups were compared.Results:Blood loss and blood transfusion in EVR group were signific’antly less than COR group(P<0.05).The median fasting period and post-operative hospital stay were shorter in EVR group(P<0.05).Post-operative complications were more often in COR group(P<0.05).WBC count in EVR group was lower in the forth day post-operation(P<0.05).RBC and Hb in EVR group were significantly higher in the forth day after operation(P<0.05).PT and APTT in EVR was lower in the first day post-operation(P<0.05).Conclusion:Endmascular repair of AAA is better for early results than conventional open repair and has the advantages of safety

less trauma and less disturbance to internal environment?
