Introduction Endoluminal stent-graft(S-G) repair for aortic pathologies replaced some part of surgical correction. However, re-intervention for endoleak and management of complications have remained to be problematic for interventionalists. The object of this study is to access the complications and endoleak after S-G repairs and management for prevention from progression of disease. Method A retrospective analysis was done in 161 patients(pts) (62.6짹11.8 yrs) who underwent S-G repair during 13 years. The indications were progression of aortic disease despite adequate medical treatment, dynamic circulatory compromization, aggravation of pain. Results In type B aortic dissection (61 pts), there have been persistent endoleak in 14 pts (22.9%, type I; 10, type II: 3, type III: 1) and endotension in 1 patient even after S-G repair. Adjuctive S-G implantation or bare metal stent insertion at proximal leakage site was performed at 3 cases without further clinical deterioration either due to endoleak or edge dissection and aneurysmal formation. Because of the progressive enlargement of false lumen diameter without endoleak, 3 pts had received surgical conversion. Coil embolization was also performed in 1 patient due to the type I endoleak. Forty-three pts (64%) are clinically followed up without complications or endoleak and additional management and 6 pts (9.8%) were lost in outpatient follow-ups. In aortic aneurysm (100 pts), 19 pts showed persistent endoleak after procedure (19%, type I; 4, type II: 10, type III: 2, type IV: 3), 8 pts showed S-G migration, disconnection with or without thrombosis after deployment who underwent surgical removal, graft interposition or fem to fem bypass surgery. Two pts had received operation due to persistent endoleak. Coil embolization was performed in 6 cases; Redo-stent graft implantation was added in 1 case due to the persistent type I endoleak. Seventy-nine pts (79%) were well tolerated without additive procedural management and 7 pts were lost in outpatient follow-ups. Conclusion S-G repair in aortic disease was promising treatment modality either in aortic but it required pertinent clinical follow-up and sophisticated expertise in management of complications and endoleak.
