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 pre-fenestration, 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.
