Endovascular repair strategy for Stanford type B aortic dissection involving visceral branches / 介入放射学杂志

ABSTRACT

At present, thoracic endovascular aortic repair (TEVAR) is the routine treatment for Stanford type B aortic dissection. Usually, during the interventional treatment only the primary entry tear, i.e. so-called proximal entry tear, is to be isolated with a stent-graft, while less intervention is adopted for the distal entry tear. With the deepening of research concerning aortic remodeling after TEVAR, the researchers have found that 25％-50％ of patients will develop aneurysmal dilation at the distal end of dissected aorta, which needs to be treated again. Among them, the treatment of entry tear at visceral branch area of the abdominal aorta has a certain degree of difficulty and technical particularity as the interventional management may affect the blood supply of vital organs. Referring to the research progress at home and abroad, this article aims to make a review about the common therapeutic methods for the entry tear at visceral branch area of the abdominal aorta.
