Convulsive-like symptoms as initial indications of basilar artery occlusion : A case series study
© 2022 The Authors..
BACKGROUND: There is little evidence regarding relevant clinical findings for the early diagnosis of basilar artery occlusion (BAO) in the prehospital setting. We focused on "convulsive-like symptoms", including convulsive seizures and other convulsive-like movements, and examined the frequency and clinical characteristics of patients with BAO having these symptoms as an initial symptom.
METHODS: In this single-center case series from 2015 to 2020, we identified patients who underwent endovascular therapy (EVT) for BAO and presented with convulsive-like symptoms between the stroke onset and initiation of emergency medical care. The clinical course and neurological findings were evaluated by reviewing the run sheets of emergency medical services and medical records.
RESULTS: Among a total of 32 patients with BAO, 7 (21.9%) developed convulsive-like symptoms before EVT, of whom 6 were men and whose median age was 72 (interquartile range, 69-78) years. These 7 patients had no history of epilepsy or stroke, and the semiology of convulsive-like symptoms was generalized in 6 of them. In only 3 of the 7 cases, emergency medical services could consider the possibility of stroke on scene, and time from hospital arrival to groin puncture was longer in those who were transported without suspicion of stroke.
CONCLUSIONS: 21.9% of our patients who underwent EVT for BAO experienced convulsive-like symptoms initially. We should be vigilant in the possibility of BAO when managing the first-time generalized convulsive-like symptoms occurring in older patients, which may enable to adequate triage and better management for patients with acute BAO.
