만성상행대동맥박리의 복원수술 후 발생한 진행핵상마비유사증후군

Abstract

A 70-year-old woman underwent cardiopulmonary bypass surgery for aorta dissection. After 10 days she developed a vertical gaze palsy, and 2 months later she presented with dysarthria, bradykinesia, postural instability, blepharospasm, and truncal tilt to the left. Brain imaging indicated old lacunes in the bilateral thalamus. Her symptoms remained unchanged during a 4-year follow-up, which seems to be incompatible with progressive supranuclear palsy (PSP). However, the clinical features of this case were suggestive of PSP-like syndrome after cardiopulmonary bypass surgery.
