Task: Answer Verification
Input (English): Question: Do changes in middle cerebral artery velocity after carotid endarterectomy identify patients at high-risk of suffering intracranial haemorrhage or stroke due to hyperperfusion syndrome?
Answer: We were unable to demonstrate that significant increases in MCAV and PI were able to predict patients at increased risk of suffering a post-operative stroke due to HS or ICH. The provision of written guidance for managing PEH in Group 2 patients was associated with virtual abolition of ICH/HS.
Output (English): no
