To describe the origin of the vessels supplying the anterior sub-axial cervical vertebrae (C3-C7) to further understand their potential influence on anterior bone loss after anterior cervical spinal surgery.
Cadaveric dissection was performed on ten adult human necks after latex perfusion of their subclavian, common carotid and vertebral arteries. The nutrient vessels of the sub-axial cervical spine were identified and traced to their origin. The course and distribution of these vessels and their nutrient foraminae are described.
In all cases the anterior nutrient vessels were derived from the thyro-cervical trunk with branches that passed over the longus coli muscles forming a leash of vessels in the pre-vertebral fascia which subsequently extended in a frond-like pattern to pass onto the anterior aspect of vertebrae. The more cranial the cervical level the fewer the number of nutrient vessels and foraminae. The distribution of the foraminae on the anterior vertebral body followed the oblique supero-medial course of the nutrient vessels.
Nutrient vessels perforate the cervical vertebrae on their anterior surface. These are derived from a leash of vessels that lie within the pre-vertebral fascia overlying the longus coli muscles. The origin of these vessels is the ascending cervical artery with a variable contribution from the transverse cervical artery.
描述供应颈椎下轴前侧椎体(C3 - C7)的血管起源,以进一步了解其对颈椎前路手术后前路骨质流失的潜在影响。
在对十具成人尸体颈部的锁骨下动脉、颈总动脉和椎动脉进行乳胶灌注后进行尸体解剖。识别颈椎下轴的营养血管并追踪其起源。描述这些血管及其营养孔的走行和分布。
在所有病例中,前侧营养血管均源自甲状颈干,其分支越过颈长肌,在椎前筋膜内形成一束血管,随后呈叶状延伸至椎体前方。颈椎节段越高,营养血管和营养孔的数量越少。椎体前部营养孔的分布遵循营养血管的斜向上内侧走行。
营养血管在颈椎椎体前表面穿入。这些血管源自位于颈长肌上方椎前筋膜内的一束血管。这些血管的起源是颈升动脉,颈横动脉有可变的贡献。
