Abstract
Recently, the survival rate of head and neck cancer patients has increased with the improvement of radiotherapy (RT) technology and comprehensive treatment. Patients were excluded if they had any of the following: a history of head and neck trauma or operations, atrial fibrillation, valvular heart disease, autoimmune vasculitis, contraindication to antiplatelet therapy, gastrointestinal bleeding or major surgery within the previous 3 months, or severe noncardiovascular coexisting condition. Two patients were diagnosed with diabetes mellitus (DM), and the mean fasting blood glucose was 5.40 +- 1.10 mmol/L. The proportion of ulcer plaques was 75.0%, 80.0%, and 71.4% in CCA, ICA, and ECA, respectively. [...]the proportion of ulcer plaques of SA and VA was 75.0% and 100%, respectively. The mean length of CCA stenosis was 59.82 +- 34.12 mm. The mean length of ICA and ECA stenosis was 15.99 +- 12.68 mm and 11.67 +- 9.87 mm, respectively. [...]the mean length of SA and VA stenosis was 27.09 +- 28.11 mm and 10.02 +- 3.23 mm, respectively.
