Technical Tips for Stent Graft Treatment

Abstract

Since the advent of a commercially available stent graft (Zenith AAA Endovascular Graft) in 2007, endovascular stent graft treatment for thoracic aortic aneurysm and abdominal aortic aneurysm (TEVAR and EVAR) has expanded rapidly in Japan, and TEVAR and EVAR are now major options of aortic repair comparable with open surgical repair. Since 2007, over 250 patients have undergone TEVAR and EVAR in our hospital and indications have increased year by year. The majority of cases were treated by the usual method, but several special techniques were necessary for unusual cases such as outsiders of Instruction for Use. In this article, we introduce some special techniques for TEVAR and EVAR based on our experiences.
