Retroaortic innominate vein is a rare anomaly. It has been reported in patients with congenital anomalies such as Tetralogy of Fallot or right aortic arch. However, isolated retroaortic innominate vein is quite rare.
A 63-year-old man was transferred to our institution because of Stanford type A acute aortic dissection. Incidentally, we noticed that the left innominate vein coursed under the aortic arch and was directed into the superior vena cava on computed tomography. We performed emergent hemiarch replacement.
Attention must be paid to the cannulation site for venous uptake and the method of myocardial protection.
主动脉后无名静脉是一种罕见的异常。它已在患有法洛四联症或右位主动脉弓等先天性异常的患者中报道。然而，孤立性主动脉后无名静脉非常罕见。
一名 63 岁男性因 Stanford 型 A 型急性主动脉夹层被转至我院。偶然间，我们在计算机断层扫描中注意到左无名静脉在主动脉弓下走行，并指向上腔静脉。我们进行了紧急的半弓置换。
必须注意静脉摄取的插管部位和心肌保护方法。
