Since the development of the technique of revascularizing the vertebral artery in its transversal and suboccipital portions, 22 revascularisation procedures of the distal vertebral artery (above C2) have been carried out in 21 patients. The earliest cases have been followed up for more than 4 years and the technique has proved to be reliable, both from the clinical and anatomical points of view. The indications were based on restoration of the vertebral axis compromised by major lesions (stenosis: 2 cases, occlusion: 14 cases) of both vertebral arteries (13 cases) or of the dominant vertebral artery in symptomatic patients (3 cases). Surgery was also offered to preserve a vascular axis which had to be sacrificed for the treatment of potentially embolic disease (aneurysm or dissection: 3 cases) or hypervascular lesions (arteriovenous malformation, tumour: 2 cases). However, the indications for distal cervical vertebral artery revascularization should be carefully considered as it is impossible to evaluate the long-term tolerance of major vertebral arterial lesions.
自从开展了椎动脉横段和枕下部分血管重建技术以来，已对21例患者实施了22次椎动脉远端（C2以上）血管重建手术。最早的病例已随访4年多，从临床和解剖学角度来看，该技术已被证明是可靠的。手术指征基于因主要病变（狭窄：2例，闭塞：14例）导致椎动脉轴受损的情况，其中双侧椎动脉（13例）或有症状患者的优势椎动脉出现病变。对于因治疗潜在栓塞性疾病（动脉瘤或夹层：3例）或高血运性病变（动静脉畸形、肿瘤：2例）而必须牺牲的血管轴，也会进行手术以保留它。然而，由于无法评估主要椎动脉病变的长期耐受性，因此应仔细考虑颈椎远端椎动脉血管重建的指征。
