In situ laser fenestration for revascularization of aortic arch during treatment for iatrogenic type A aortic dissection. (a) Aortography was performed via the left femoral artery to measure the diameters of the ascending aorta and arch vessels; (b) Aortography was performed after stent implantation demonstrated no endoleak, and aneurysm and dissection; (c-e) CTA presented possible access sites of fenestration, stent placement, patency of the aortic arch branches.
