Task: Answer Verification
Input (English): Question: Do atherosclerotic plaque rupture and intraplaque hemorrhage correlate with symptoms in carotid artery stenosis?
Answer: Almost 70% of plaque specimens demonstrated thrombus, intraplaque hemorrhage, or both. Thrombosis was observed in one fourth of specimens, and intraplaque hemorrhage in almost two thirds of specimens. Sixty four percent of plaques demonstrated neovascularization. It was not possible to demonstrate that complicated plaques (plaque rupture, thrombosis, intraplaque hemorrhage) are associated with symptoms, and it appears that such plaques may occur at any time, irrespective of symptoms.
Output (English): no
