摘　　要：BACKGROUND A 63-year-old female was diagnosed with acute Stanford type A aortic dissection.The patient had pain in the chest and back for 1 wk.The computed tomography angiography(CTA)showed Stanford type A aortic dissection(Myla type III aortic arch).The intimal tear was located at the top of the aortic arch and retrograded to the ascending aorta.CASE SUMMARY Preoperatively,a three-dimensional(3D)-printed model of the aortic arch was made according to CTA data.Then,under the guidance of the 3D-printed aortic model,a pre-fenestrated stent-graft was customized,and the diameter of the stent-graft was reduced intraoperatively by surgeons.3D printing,triple prefenestration,and reduced diameter techniques were used during the surgery.The CTA examinations were performed at the 3rd mo and 1st year after the surgery;the results showed that the aortic dissection was repaired without endoleak,and all three branches of the aortic arch remained unobstructed.CONCLUSION Applying the triple pre-fenestration technique for aortic arch lesions was feasible and minimally invasive in our case.The technique provides a new avenue for thoracic endovascular aortic repair of Stanford type A aortic dissection.
