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.
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 3 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.
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.
一名63岁女性被诊断为急性斯坦福A型主动脉夹层。患者胸痛、背痛1周。计算机断层扫描血管造影(CTA)显示为斯坦福A型主动脉夹层(迈拉III型主动脉弓)。内膜撕裂位于主动脉弓顶部,并逆行至升主动脉。
术前,根据CTA数据制作了主动脉弓的三维(3D)打印模型。然后,在3D打印的主动脉模型引导下,定制了预开窗支架型人工血管,术中由外科医生减小了支架型人工血管的直径。手术中采用了3D打印、三重预开窗和减小直径技术。术后3个月和1年进行了CTA检查;结果显示主动脉夹层修复成功,无内漏,主动脉弓的三个分支均保持通畅。
在我们的病例中,对主动脉弓病变应用三重预开窗技术是可行的且微创。该技术为斯坦福A型主动脉夹层的胸主动脉腔内修复提供了一条新途径。
