Background: Intravenous thrombolysis and mechanical thrombectomy are the first-line reperfusion therapies for acute ischemic stroke. Here, we describe utility of diffusion magnetic resonance imaging (MRI) fiber tractography 123I-iomazenil benzodiazepine receptor single-photon emission computed tomography to estimate prognosis post-stroke aphasia after successful therapy. Case report: An 81-year-old man was admitted hospital approximately 3.5 h onset symptoms, including decreased consciousness, right hemiparesis, aphasia. MRI revealed cerebral infarction due M1 segment occlusion. alteplase followed by endovascular resulted in recanalization left middle artery territory. A subsequent showed no new or hemorrhagic lesions. Although patient’s motor hemiparesis gradually recovered, persisted. Diffusion performed 2 weeks admission partial injury arcuate fasciculus, indicated lower fractional anisotropy values than on contralateral side. density also detected perisylvian temporoparietal cortices. The patient clear signs further improvement chronic stage discharged a nursing home 3 months. Conclusions: application functional neuroimaging techniques assess neuronal damage primary brain regions therapy large-vessel occlusion may allow an accurate This have direct clinical implication navigating subacute-to-chronic phases rehabilitative care.

Impact of D-dimer on the outcomes of endovascular thrombectomy for acute ischemic stroke: A systematic review and meta-analysis

There has been growing data about the association between D-dimer levels and thrombectomy outcomes in acute ischemic stroke patients (AIS) with no cumulative evidence. This systematic review meta-analysis aim to discuss analyze findings of current studies provide more robust evidence this regard.
