A proximal entry tear located in the proximal trunk of the left subclavian artery is confirmed by balloon inflation blocking and sealed with an occluder

Aortic dissection （AD） is a catastrophic disease involving the aorta. Most intimal tears are located in the ascending aorta or the first portion of the descending aorta.1 It is a rare case that the proximal tear originates from the left subclavian artery （LSA）. Virtual endoscopy （VE） technology could provide us a specific perspective to see from intraluminal to the outside and was especially helpful to look for and indentify complicated intimal tears.^2 Vascular occluder is a useful device to treat vessel diseases alone or combined with other appratus.
