3 Figure 2 Diagram of the simplified technique. A, The arch is transected obliquely, and almost all of the lesser curvature is resected. The distal hemiarch is reserved. B, The stented part of the graft is implanted into the descending aorta with the proximal edge of the stent just distal to the origin of left subclavian artery, and the graft free of stent is located inside the reserved arch. C, According to the arch incision, the redundant vascular graft outside the arch is pruned away. The greater curvature of the vascular graft is cut to expose the orifices of 3 vessels. D, A continuous suture is performed around the orifices of 3 branches to attach the vascular graft to the native aortic arch. E, The anastomosis of the proximal and distal vascular grafts combined with the native vessel wall of aortic arch is accomplished with a continuous suture using an open aortic technique.

4 Figure 3 CTA of a patient with acute Stanford type I dissection undergoing simplified aortic arch repair before operation (A-C) and 3 months after the surgery (D-G). Preoperative scan shows that the true lumen is compressed by a huge false lumen in the descending aorta (A-C). Postoperative scan shows that the stent graft expanded fully and that the false lumen is almost closed completely with thrombosis throughout the descending aorta. No contrast medium endoleak is detected at the greater curvature of the arch.

7 Figure 6 Survival of patients with acute DeBakey type I aortic dissection in the simplified group and the total arch group during follow-up. No significant difference was found in survival between the 2 groups (P = .78).

8 Figure 7 Freedom from aortic event of patients with acute DeBakey type I aortic dissection in the simplified group and the total arch group during follow-up. The aortic event rate was not significantly different between the 2 groups (P = .84).
