Angiography of high cervical extramedullary tumours

Vertebral angiography was performed in two cases of extramedullary tumour of the upper cervical spine. The technical feasibility and relatively low risk of catheter vertebral angiography makes it a useful procedure to be performed in addition to myelography in the pre-operative evaluation of such lesions. The information thus obtained includes the relationship of the tumour to the vertebral arteries and other vital structures, demonstration of the blood supply, and evidence as to tumour type.
