Blood-brain barrier leakage increases with small vessel disease in acute ischemic stroke
Conclusions: Global SVD burden is associated with increased BBB leakage in both acutely ischemic and nonischemic area. Our results support that SVD score has construct validity, and confirm a relation between SVD and BBB disruption also in patients with acute stroke.
CONCLUSIONS: Thrombus permeability assessed on dynamic CTA could be a better predictor of outcome after reperfusion therapy than that assessed on conventional single-phase CTA.

Conclusions: Non-standard criteria for rtPA eligibility were evident in all three countries and could, in part, explain comparably low use of rtPA. Differences in the use of standard criteria may signify practitioner intolerance for those derived from original efficacy studies that are no longer relevant.Intervent Neurol 2019;8:1 –12

In all patients both MRS an...
Conclusion: This randomized study will provide important information about the physiological effects of BP reduction on cerebral perfusion after intravenous thrombolysis in AIS.
Abstract We investigated structural and functional differences in primary and pial collateral circulations in adult normotensive male and female Wistar rats. Male (n=10) and female (n=7) rats were subjected to middle cerebral artery (MCA) occlusion and changes in relative cerebral blood flow (rCBF) in MCA and pial collateral territories were measured by multi-site laser Doppler flowmetry. Rats were then transcardially perfused with a mixture of carbon black and latex, perfusion fixed and imaged to compare primary and pial collateral structure between males (n=4) and females (n=3), including lumen diameters and num...
Conclusions: In our population, patients with CAO clinically present with severe strokes. Isolated occlusions of the extra- or intracranial segments of the carotid are more frequent than tandem occlusions. Successful recanalization after thrombectomy is achieved in most of the patients, but association with favorable functional outcome is poor. Clinical evolution is similar in patients treated with PMT and BT. Intracranial symptomatic hemorrhage after treatment is associated with higher intrahospital mortality and worse 3 months-mRS. Poor perfusion-CT mismatch, symptomatic hemorrhage, and isolated CAO are independent predi...
CONCLUSION: Findings indicate the beneficial effects of HCG and Trolox on the improvement of memory and the number of healthy cells in the hippocampal region. It is worth noting that the amount of apoptosis in the hippocampus was significantly reduced by Trolox, HCG and Carnosic acid. PMID: 30227824 [PubMed - as supplied by publisher]

We present a diagnostic strategy in a pregnant woman with suspect of acute stroke. We perform magnetic resonance with arterial spin labeling sequence, an X-ray and contrast medium safe perfusion technique. Arterial spin labeling can detects collateral vessels in patient with acute ischemic stroke. Demonstrating collateral vessels is relevant for better understanding prognosis and for improving the diagnostic assessment in pregnancy.
