Nerve Root Compression Due to Contralateral Compensatory Hypertrophy: A Rare Case of Vertebral Artery Thrombosis

Abstract

In the patient who complained of dizziness, thrombus was observed in the right vertebral artery. Compression was detected in the nerve root due to compensatory hypertrophy in the left vertebral artery. In conclusion, in cases of unilateral vertebral artery thrombosis, should be aware of the pathologies that may develop in adjacent structures due to compensatory hypertrophy. Teaching Point: An occluded vertebral artery (VA) can cause contralateral VA hypertrophy, which can cause various pathologies including nerve root compression.
