Associations of intracranial arterial stenosis and cerebral small vessel diseases with acute ischemic lesions in spontaneous intracerebral hemorrhage
Clinical Report: Links Between Intracranial Arterial Stenosis and DWI Lesions
Overview
This study investigates the relationship between cerebral small vessel disease (CSVD), intracranial arterial stenosis (ICAS), and diffusion-weighted imaging (DWI) lesions in patients with spontaneous intracerebral hemorrhage (ICH). It finds that severe CSVD burden and moderate to severe ICAS are significantly associated with DWI lesions, particularly when both conditions coexist.
Background
Cerebral small vessel disease (CSVD) and intracranial arterial stenosis (ICAS) are prevalent conditions that can complicate the clinical course of patients with spontaneous intracerebral hemorrhage (ICH). Understanding the interplay between these conditions and their contribution to ischemic lesions is crucial for improving patient management and outcomes. This study aims to clarify the associations between CSVD, ICAS, and DWI lesions in ICH patients.
Data Highlights
Parameter
Value
DWI lesions prevalence
25.3%
OR for severe CSVD burden
3.56 (95% CI 2.22–5.72, p < 0.001)
OR for modified CSVD score
4.66 (95% CI 2.86–7.61, p < 0.001)
OR for moderate to severe ICAS
2.27 (95% CI 1.39–3.77, p = 0.019)
OR for ICAS with moderate CSVD
4.44 (95% CI 1.85–10.69, p = 0.001)
Key Findings
25.3% of ICH patients presented with DWI lesions.
Severe total CSVD burden significantly correlates with DWI lesions (OR 3.56).
A six-point modified CSVD score enhances prediction of DWI lesions (OR 4.66).
Moderate to severe ICAS is associated with DWI lesions (OR 2.27).
The combination of moderate to severe ICAS and moderate CSVD burden significantly increases the risk of DWI lesions (OR 4.44).
Clinical Implications
Clinicians should be aware of the significant association between severe CSVD burden and DWI lesions in ICH patients, as this may influence treatment decisions and prognostic assessments. The presence of both ICAS and CSVD may indicate a higher risk for ischemic complications, warranting closer monitoring and management strategies.
Conclusion
The findings suggest that both severe CSVD and ICAS contribute to the development of DWI lesions in ICH patients, highlighting the importance of assessing these conditions in clinical practice.
