Endovascular Aneurysm Repair For Aortic Aneurysm

Objective: To evaluate the method and clinical effect of Endovascular aortic repair(EVAR) for aortic aneurysm,the indication for EVAR was also discussed.Methods:From April 2005 to January 2009,25 cases of aortic aneurysm were treated by EVAR,15 cases were aortic dissecting aneurysm,8 cases were abdominal aortic aneurysm(AAA), 1 case was aneurysm of common iliac artery and 1 case was pseudo-aneurysm of thoracic aortic. They were treated with endovascular aortic repair(EVAR) in accordance with their disease conditions.The effects and complications were evaluated.Results: EVAR were successfully performed in all cases. Pseudo-cavity in 15 cases of aortic dissection were disapeared after stent deployment,8 cases of AAA and 1 case aneurysm of common iliac artery were successfully isolated,the rupture orifice in the case with pseudo-aneurysm was successfully occluded. This group included 8% 30-day death rate.And without misplace of stent grafts,migration,endo-leakage, conversion to open surgery and paraplegia complication.Follow-up period ranged from 2 to 24 months,no endo-leakage or stent graft migration was found.Conclusion: EVAR is an effective,less trauma and safe when the indications are carefully selected.It may serve as an alternative treatment for most aortic aneurysm,but long-term results needs further study.
