We present the use of radial artery graft for bypass of the proximal superficial temporal artery to the proximal middle cerebral artery. Six adult cadaver sites were used bilaterally. After apterional incision, 2x2-cm minicraniectomy was performed which began 2 cm behind the zygomatic process of the frontal bone. The superficial temporal artery was transsected before exposing the zygomatico-orbital artery branch. The proximal side of the radial artery graft was anastomosed end-to-end to the proximal superficial temporal artery and the distal side end-to-side to the proximal middle cerebral artery. The mean calibers of the proximal superficial temporal artery and largest trunk of the middle cerebral artery were 2.25+/-0.35 mm and 2.3+/-0.3 mm, respectively. The average graft length was 85+/-5.5 mm. We conclude that such bypasses are simpler than proximal middle cerebral artery revascularization using long vein grafts. This method proves that the caliber of the proximal superficial temporal artery is more suited to providing sufficient flow than the distal superficial temporal artery, and the graft is short. Such bypasses to the middle cerebral artery may be an alternative to those from the distal superficial temporal artery or extracranial carotid artery.
我们介绍了使用桡动脉移植物将颞浅动脉近端与大脑中动脉近端进行搭桥的方法。双侧使用了6个成人尸体部位。在翼点切口后，进行2×2厘米的小型颅骨切除术，起始于额骨颧突后方2厘米处。在暴露颧眶动脉分支之前切断颞浅动脉。桡动脉移植物的近端与颞浅动脉近端进行端端吻合，远端与大脑中动脉近端进行端侧吻合。颞浅动脉近端和大脑中动脉最大主干的平均管径分别为2.25±0.35毫米和2.3±0.3毫米。移植物平均长度为85±5.5毫米。我们得出结论，这种搭桥手术比使用长静脉移植物进行大脑中动脉近端血管重建更简单。该方法证明，颞浅动脉近端的管径比颞浅动脉远端更适合提供足够的血流，且移植物较短。这种大脑中动脉搭桥术可能是颞浅动脉远端或颅外颈动脉搭桥术的一种替代方法。
