MR revealed a small infarct size and large area of low perfusion in the left hemisphere with the occlusion of left middle cerebral artery (MCA). (A) Diffusion-weighted MRI revealed an acute infarct in the left basal ganglia. (B) MR angiography showed that the M1 segment was occluded. (C) MRI re-examination after 8 days revealed an acute infarct in the left basal ganglia region with a small dot-like embolic infarct in the cortex. (D) There were large areas of low perfusion in the left MCA territory.

The process of left middle cerebral artery (MCA) angioplasty.(A) A left MCA angioplasty. (B) The M1 segment of the left MCA was recanalized after angioplasty. (C) Digital subtraction angiography examination indicated that recanalization was successful after 40 days.

MRI examination. (A) MRI revealed multiple clusters of ischaemic infarctions in bilateral cerebellar hemisphere. (B) Both vertebral arteries and basilar artery were occluded.

Second MRI examination. On the ninth day of hospitalisation, MRI suggested worsening of bilateral cerebellar infarctions and the involvement of brainstem.

Recanalization of the occluded basilar artery by percutaneous transluminal angioplasty and stenting. (A) Right ICA angiography revealed that the superior segment of the basilar artery and bilateral posterior cerebral arteries were partially supplied by posterior communicating artery. (B) Basilar artery was completely occluded in the middle segment and left posterior inferior cerebellar artery (PICA) showed compensatory enlargement. (C) Micro-catheter passed through the stenosis of the inferior segment of the basilar artery and revealed basilar artery occlusion beyond the middle segment. (D) After balloon dilation and implantation of the self-expandable stent, basilar artery was completely recanalized.
