BACKGROUND AND AIMS: Small fraction of lacunar stroke patients have an early fluctuating course, described as progressive lacunar syndrome [PLS].We studied the predictors and short term outcome of progressive lacunar strokes in comparison with those with an early stable course.
MATERIALS AND METHODS: Single centre retrospective study where patients with lacunar strokes from 2016 to 2020 were included in the study. Progression was defined as increase in stroke severity [NIHSS] by ≥2 points from baseline without imaging evidence of new infarcts or haemorrhagic transformation. We compared the clinical variables, risk factors, imaging, treatment received and 1 year outcome of subjects with PLS with those with a stable course, with modified Rankin score 0-2 taken as good outcome.
RESULTS: Of the 216 patients with a mean age 63.17 years, progressive course was noted in 56 subjects [26 %].Majority of the fluctuations occurred within 24 h of onset of symptoms. Though stroke severity at admission was comparable between the 2 groups, discharge and 1 year outcome was poorer in those with an early progressive course. We found that presentation as pure motor syndrome, hypertriglyceridemia and thrombolytic therapy were predictors of poor outcome in progressive lacunar strokes, while age, risk factors, infarct location or leukoaraiosis failed to show an association. Thalamic infarcts and atypical lacunar syndromes were associated with a stable course.
CONCLUSION: Progressive course is seen in a quarter of lacunar strokes and they have poorer outcome at 1 year. Our finding of thrombolysis being associated with worse outcome in PLS patients, should alert physicians regarding need for more definitive therapies for this condition.
