Abstract：
OBJECTIVE: A broad armamentarium of microsurgical techniques affords flexibility to surgeons when choosing a procedure that is best tailored to fit the anatomy of an individual. Herein, we report on the feasibility of using the deep cervical artery (DCA) to revascularize the vertebral artery (VA) via a DCA-V3 bypass graft.
METHODS: Fourteen DCAs from 7 injected cadaveric heads were located and traced. The diameter of the main trunk of the DCA was measured bilaterally at the C3 level. The proximal vertebral branches of each DCA were then severed and the main trunk of the DCA was transposed superiorly onto the V3 segment of the VA, which was also exposed bilaterally.
RESULTS: The DCA was identified and traced bilaterally on all specimens. The diameter of the main trunk of the DCA at the C3 level ranged from 1.03 to 2.79 mm. The mean diameter of the main trunk of the DCA at this level was found to be 1.52 ± 0.60 mm for the right side and 1.46 ± 0.54 mm for the left side. After releasing the proximal vertebral branches of the DCA, all arteries were able to be transposed to the ipsilateral VA.
CONCLUSIONS: Based on the mean diameter of the DCA reported in extant literature and this study, the blood flow volume of the DCA makes it a viable candidate to bypass the proximal VA.

摘要：
目的：广泛的显微外科技术为外科医生选择最适合个体解剖的手术提供了灵活性。在这里，我们报告了通过DCA-V3旁路移植使用颈深动脉（DCA）重建椎动脉（VA）的可行性。
方法：对来自7个注射尸体头部的14个DCA进行定位和追踪。在C3水平双侧测量DCA主干的直径。然后切断每个DCA的近端椎骨分支，并将DCA的主干向上转移到VA的V3段上，这也是双边暴露的。
结果：在所有标本上对DCA进行了鉴定和双侧追踪。C3级DCA主干的直径范围为1.03至2.79mm。在该水平下，DCA主干的平均直径右侧为1.52±0.60mm，左侧为1.46±0.54mm。在释放DCA的近端椎骨分支后,所有动脉均可转位至同侧VA.
结论：根据现有文献和本研究报告的DCA的平均直径，DCA的血流量使其成为绕过近端VA的可行候选者。
