Aims:
To find neurological or neuroimaging signs to predict neurological deterioration in acute lacunar infarctions.
Methods:
Sixty-one consecutive patients with a supratentorial lacunar infarct, who were admitted within 48 h, were studied retrospectively. Progressive-type stroke (PS) was defined as progressive motor deficits that arose within 7 days after onset, by using the motor ratings of the National Institutes of Health Stroke Scale.
Results:
Sixteen patients (26%) were classified into the PS group. In the PS group, fluctuating or progressing onset (81 vs. 42%, p = 0.009), leg-predominant motor deficits on admission (63 vs. 16%, p = 0.001) and corona radiata lesion on diffusion-weighted MRI (100 vs. 69%, p = 0.013) were all more frequent than in the non-PS group.
Conclusion:
Bedside neurological assessment and MRI findings may allow us to predict PS and start early intensive treatment for preventing further neurological deterioration.
