To the editor: Winzelberg's recent article (1) on parathyroid imaging is an excellent review of current approaches to localization of abnormal parathyroid glands. Unfortunately, the discussion of parathyroid angiography is marred by two errors we would like to correct.
First, the blood supply to the cervical spinal cord does not arise from the proximal thyrocervical trunk, as stated by Winzelberg. Although textbooks state that twigs to the cervical spinal cord arise from the ascending cervical artery, a branch of the thyrocervical trunk (2), we have seen convincing evidence of supply to the spinal cord in only 2 of over 1000
