The correlation between carotid siphon calcification and lacunar infarction

Area of Science:

• Neurology
• Radiology
• Vascular Medicine

Background:

• Small-vessel disease is a common cause of lacunar infarction.
• Carotid siphon (CS) calcification is a potential indicator of cerebrovascular disease.

Purpose of the Study:

• To investigate the correlation between carotid siphon calcification and lacunar infarction.
• To determine if CS calcification can predict the occurrence of lacunar infarction.

Main Methods:

• Retrospective study of 445 patients over 40 years old.
• Classification into groups based on lacunar infarction count (0, 1-3, 4+).
• Evaluation of CS calcification severity using CT scans and a five-point scale; statistical analysis with ANOVA and logistic regression.

Main Results:

• Significant differences in CS calcification scores were found among groups with varying lacunar infarction counts (P < 0.05).
• Higher CS calcification scores were associated with increased rates of lacunar infarction.
• CS calcification, age, and hypertension were identified as significant risk factors for lacunar infarction (P < 0.05).

Conclusions:

• Carotid siphon calcification is correlated with the occurrence of lacunar infarction.
• The degree of CS calcification may serve as a predictor for future lacunar infarction.
