Authors divided lacunes into very small (<3 mm) and small (3-7 mm) and larger (8-20 mm). The hypothesized mechanism for very small lacunes and small lacunes was lipohyalinosis and larger lacunes was microatheroma.
Risk factors for small lacunes (lipohyalinosis) in 1548 patients analyzed included age, African American race, HTN, diabetes, ever smoking. HBA1C could be substituted for DM.
Very small lacunes had similar risk factors as small lacunes. Diabetes was key risk factor here.
8-20 mm lacunes (microatheroma) were associated with ever smoking, age, and LDL levels.
Conclusion is that diabetes leads to disorder of systemic microcirculation leading to very small lacunes. LDL and smoking lead to microatheroma
