Background:
Rapid neurological recovery from subacute to chronic ischemic stroke in subset of patients following carotid revascularization was observed.
Objective:
Retrospective analysis of data of the patients who had shown rapid recovery from subacute to chronic ischemic stroke following revascularization by Carotid stenting.
Materials And Methods:
We retrospectively analyzed pooled data from our carotid stenting patients done during January 2009 to January 2020.The inclusion criterion of the study was patients with rapid recovery within 24 h following revascularization by carotid stenting. There were total of 12 such patients. There were 8 males and 4 females. Apart from NIHSS, stroke severity was measured on MRI by ASPECTS score and cognitive function by MMSE. Each of these patients has undergone Carotid Stenting with distal protection for high-grade stenosis.
Results:
All of these 12 patients had Prestenting ASPECTS score ranging 8-10. Prestenting NIHSS score was ranging from 6-12 with an average of 8. Postprocedure NIHSS score was decreased to a range of 0-4 with average of 3.Prestenting MMSE was ranging 14-20 with an average of 18 score which turned into Post-stenting MMSE scale ranging 24-28 with an average of 26.Each of these patients shows decrease in NIHSS score by at least 50% in 24h to be called rapid recovery or Lazarus phenomenon. Additionally, they show significant improvement in cognitive function on MMSE scale.
Conclusion:
Rapid recovery from subacute to chronic ischemic stroke following revascularization by Carotid Stenting is potentially feasible in subset of patient who has mild to moderate deficit but high ASPECTS score.
