RESUMEN

BACKGROUND: The term 'Capsular warning syndrome (CWS)' refers to recurrent, stereotypical transient ischemic attacks, either motor, sensory or both, without cortical symptoms or signs. Of these patients, 42-71% go on to develop infarcts. There are no defined treatment guidelines for this lesser known entity. METHODS: We studied 9 patients who presented over last 2 years to our hospital with recurrent and stereotypical transient ischemic attacks suggestive of capsular warning syndrome. Their clinical characteristics, neuroimaging findings, relevant etiological investigations, management and outcomes were studied. RESULTS: Seven out of 9 patients were under 40 years of age. The commonest presentation in our series was a pure motor syndrome. The duration of neurologic deficits ranged from 5 minutes to 20 minutes with complete recovery in between episodes. Three patients had concordant abnormalities on CT brain angiography. Five out of 9 patients received IV thrombolysis with t-PA. One patient worsened neurologically post thrombolysis, whilst the others improved clinically. DISCUSSION: Despite multiple hypotheses, the pathogenesis and management of CWS has not been established clearly. Due to fluctuating neurological symptoms with complete recovery in between the episodes, there is a dilemma concerning treatment of such patients with intravenous thrombolysis. However, intravenous thrombolysis appears to be safe in CWS as in acute ischemic stroke, followed by treatment with antiplatelet agents.
