Association between renal insufficiency and lesion characteristics of posterior reversible encephalopathy syndrome
Posterior reversible encephalopathy syndrome (PRES) is characterized by cerebral blood flow dysregulation and the blood–brain barrier (BBB) disruption. While renal insufficiency has been considered a factor in...

Open AccessAssociation between arterial tortuosity and early neurological deterioration in lenticulostriate artery infarction
Early neurological deterioration (END) in lenticulostriate artery (LSA) infarction is associated with perforating artery hypoperfusion. As middle cerebral artery (MCA) tortuosity may alter hemodynamics, we inv...

Open AccessIn-stent restenosis and stented-territory infarction after carotid and vertebrobasilar artery stenting
Prognosis after vertebrobasilar stenting (VBS) may differ from that after carotid artery stenting (CAS). Here, we directly compared the incidence and predictors of in-stent restenosis and stented-territory inf...

Open AccessFactors associated with two different stroke mechanisms in perforator infarctions regarding the shape of arteries
Two different stroke mechanisms are involved in small vessel disease: branch atheromatous disease (BAD) and lipohyalinotic degeneration (LD). We compared mechanisms of stroke in lenticulostriate arteries (LSA)...

High serum total cholesterol associated with good outcome in endovascular thrombectomy for acute large artery occlusion
The effect of cholesterol on the functional outcome after endovascular thrombectomy (EVT) is still controversial. This study aimed to investigate whether the lipid profile is associated with the EVT prognosis.

Article
Open AccessPrior intracerebral hemorrhage and white matter hyperintensity burden on recurrent stroke risk
Prior intracerebral hemorrhage (ICH) is associated with increased risk of ischemic stroke. Since white matter hyperintensity (WMH) is associated with ischemic stroke and ICH, this study aimed to evaluate the r...

Article
Open AccessBlood pressure variability is related to faster cognitive decline in ischemic stroke patients: PICASSO subanalysis
Blood pressure variability (BPV) is associated with higher cardiovascular morbidity risks; however, its association with cognitive decline remains unclear. We investigated whether higher BPV is associated with...

Article
Post-stroke cognitive impairment as an independent predictor of ischemic stroke recurrence: PICASSO sub-study
To devise appropriate preventive strategies after stroke, knowledge of the association between post-stroke cognitive impairment (PSCI) and prognosis of stroke patients is important. We investigated the associa...
