ABSTRACT

Objective To investigate the technical details and therapeutic effect in treating StarIdford B aortic dissection by endovaseular aortic repair(EVAR). Methods We retrospectively review 115 type B aortic dissection cases undergoing the procedure of mini-traumatic EVAR from November 1998 to February 2009.There were 71 male patients and 44 female patients with a mean age of55.7 years and follow up period from 7 to 83 months for 75 cases. Results The procedure Was technically successful in 113 cases and 122 stent grafts were placed with hybrid surgery being carried out in 3 cases of carotid artery bypass.Severe perioperative complications included subclavian steal syndrome in 4 eases,pulmonaryinfections in 3 cases.arterial embolism in 2 cases,acute cerebral infarction in 2 cases,kidney tailure in 2 cases.alimentary tract hemorrhage,graft infection,acute intestinal ischemia and type A dissection occurred in one each case respectively.Five cases died perioperatively.Among the 75 cases that were fouowed up,there were 9 eases with type I endoleak and at last 5 cases redid endovaacular repmr.2 cases with secondary type A dissection accepted graft replacement.There were 6 deaths during the follow-up period,4 dying of acute myocardial infarction(2 cases),cerebral hemorrhage(1 case),type A dlssection (1 case)respectively,the causes of other2 deaths were not confirmed. Conclusion EVAR was effective for Standford B aortic dissection as shown by midterm follow up.
