Staged repair of extensive thoracic aortic aneurysms puts certain patients at risk of rupture. We report the case of a patient with Marfan syndrome who presented with subacute type-A aortic dissection and a large descending aortic aneurysm. We used the arch-first technique with a commercially available Dacron T-graft. A clamshell incision was used for exposure. A button of arch vessels was anastomosed to the T-graft. Antegrade cerebral perfusion was established through the side branch. The distal end of the graft was anastomosed to the descending aorta and the proximal end to a composite graft. The duration of cerebral ischemia was 30 minutes; antegrade cerebral perfusion lasted 52 minutes. The patient experienced no neurologic dysfunction and was discharged with no major deficit. This technique shortens brain-ischemia time and is a good option if the risk of rupture of the descending component of an extensive thoracic aortic aneurysm is high. To the best of our knowledge, this is the 1st reported case in which the arch-first technique has been used with a commercially available T-graft to treat subacute type-A aortic dissection in a patient with Marfan syndrome.
分期修复广泛性胸主动脉瘤会使某些患者面临破裂风险。我们报告了一例患有马凡综合征的患者,该患者表现为亚急性A型主动脉夹层和巨大的降主动脉瘤。我们采用了使用市售涤纶T型移植物的先主动脉弓技术。采用蛤壳状切口进行暴露。将主动脉弓血管纽扣状部分吻合至T型移植物。通过侧支建立顺行性脑灌注。移植物远端吻合至降主动脉,近端吻合至复合移植物。脑缺血持续时间为30分钟;顺行性脑灌注持续52分钟。患者未出现神经功能障碍,出院时无明显缺陷。该技术缩短了脑缺血时间,并且如果广泛性胸主动脉瘤降部破裂风险较高,是一个不错的选择。据我们所知,这是首例报道使用市售T型移植物的先主动脉弓技术治疗马凡综合征患者的亚急性A型主动脉夹层的病例。
