Ectatic vertebral artery associated medullary compression treated with microvascular decompression: a case report and review of literature.

Background: Vertebral artery compression syndrome is a rare condition defined as the clinical presentation of dizziness, vertigo, ataxia, dysarthria, dysphagia, progressive or acute paralysis, hemisensory loss, and cervical myelopathy secondary to compression of the medulla and upper spinal cord by the vertebral artery.

Case description: Here we describe a 57-year-old Mexican-American male with bulbar symptoms, positional vertigo, and diplopia. The patient's symptoms were managed through microsurgical decompression of the medulla utilizing a far lateral transcondylar approach. The patient reported clinical improvement on follow-up.

Conclusion: This case underscores the clinical complexity and heterogeneity of this rare neurovascular pathology and the importance of elucidating the pathophysiological mechanisms underlying the symptomatic presentation of vertebral artery compression syndrome.
