Backgrounf and Objects: There is a few data with the safety and long term clinical outcome after thoracic endovascular aortic repair(TEVAR) for complicated aortic dissection. The objective of this study is to investigate safety and mid-term clinical outcome after TEVAR for complicated aortic dissection during follow up. Methods and Results: This was the observational retrospective study. 12 patients who were managed with TEVAR from Jan. 2005 to Dec. 2009 at our hospital were enrolled. The 12 patients consisted of 6 cases of acute descending aortic dissection, 6 cases of chronic descending aortic dissection. 4 cases of malperfusion syndrome were treated with aortic stent graft(n=2), selective branch artery stenting(n=4, renal 2, celiac 2 carotid 2 common iliac 1), fenestration(n=1), combined procedure(n=4). There were 4 cases of aortic stent grafting for ruptured aortic dissection(33%). There were 3 cases of hospital mortality, which were 2 cases of ruptured aortic dissection(25%). The causes of death were hypoxic brain damage, hepatic failure and bleeding before procedure. Mortality during 6 months showed 25%(3/12). 3 cases showed regressions of huge aneurysm formation after TEVAR after 1 year. Conclusion: TEVAR for complicated aortic dissection may be a safe procedure with good mid-term clinical outcomes. More clinical data and long term follow up are needed.
