  • G46.0 Middle cerebral artery syndrome
  • G46.1 Anterior cerebral artery syndrome
  • G46.2 Posterior cerebral artery syndrome
  • G46.3 Brain stem stroke syndrome
  • G46.4 Cerebellar stroke syndrome
  • G46.5 Pure motor lacunar syndrome
  • G46.6 Pure sensory lacunar syndrome
  • G46.7 Other lacunar syndromes
  • G46.8 Other vascular syndromes of brain in cerebrovascular diseases
