Abstract
Objective: We aim to propose the term “vertebral artery compression syndrome” to describe a group of patients with a variety of clinical symptoms caused by vertebral artery compression of the medulla or spinal cord.Methods: We conducted the prospective case study in a university teaching hospital. Eleven patients who fulfilled the diagnostic criteria of vertebral artery compression syndrome and 22 age- and sex- matched controls were recruited. Clinical presentation and radiological findings of patients with vertebral artery compression syndrome were assessed and recorded. The basilar artery diameter was measured at the midpons level on T2 weighted MR images and compared between both groups.Results: Medullary compression was observed in 10 of 11 patients. The most common clinical presentation is dizziness, vertigo, imbalance, or ataxia followed by limb weakness. Cervical spinal cord compression was observed in one patient who presented with neck pain and left leg weakness. The mean basilar artery diameter was similar between patients and controls (3.95 ± 0.41 vs. 3.81 ± 0.43 mm).Conclusions: Vertebral artery compression of medulla and spinal cord may cause various clinical symptoms. Future studies are needed to further clarify the prevalence, natural history and treatment of this condition.
Highlights
Vertebrobasilar dolichoectasia, or intracranial arterial dolichoectasia, is an uncommon neurovascular disorder characterized by elongation and enlargement of the vertebrobasilar arteries [1,2,3]
The definition of vertebral artery compression syndrome” (VACS) was proposed by Dr Qi Li and VACS was operationally defined as: Imaging evidence of compression of the medulla/upper spinal cord by vertebral artery and the compression causing corresponding symptoms
Patients were included in the study if they had imaging evidence of compression of the medulla/upper spinal cord by vertebral artery and the compression is responsible for corresponding symptoms
Summary
We conducted the prospective case study in a university teaching hospital. Eleven patients who fulfilled the diagnostic criteria of vertebral artery compression syndrome and 22 age- and sex- matched controls were recruited. Clinical presentation and radiological findings of patients with vertebral artery compression syndrome were assessed and recorded. The basilar artery diameter was measured at the midpons level on T2 weighted MR images and compared between both groups
