We present a case of subacute IST after stenting treatment of an isolated higher stenosis of the right middle cerebral artery (MCA). Analysis of clinical features and emergent brain image helped to indicate the pathophysiological mechanism underlining the symptoms of this patient. Emergent Transcranial Doppler (TCD) helped to evaluate the compensatory collateral circulation and provided good supporting evidence in deducing the mechanism of IST. Slightly larger size of the implanted stent that caused dissection or vascular endothelium injury was presumed in this patient. Persistent evidence of inflammatory factors might also contribute to IST in this patient.
