Group A: Acute cerebral infarction without hemorrhagic transformation. Group B: Hemorrhagic transformation postacute cerebral infarction. ICAs: Internal carotid artery system. VBs: Vertebral basilar system. Sites 0, 1, and 2 represent small, medium, and larger areas of infarction, respectively. a. site 0 vs site 1; b: site 1 vs site 2; c: site 0 vs site 2
