Objective: To explore the value of whole-brain perfusion parameters combined with multiphase computed tomography angiography (MP-CTA) in predicting the hemorrhagic transformation (HT) of ischemic stroke. Methods: A total of 64 patients with ischemic stroke who underwent noncontrast computed tomography, computed tomography perfusion imaging, and computed tomography angiography before treatment from August 2017 to June 2019 were included retrospectively. The perfusion parameters cerebral blood volume (CBV), cerebral blood flow (CBF), time to peak (TTP), mean transit time (MTT), time to maximum (Tmax), and permeability surfac...

Conclusion: In patients with hemorrhagic MMD, the CBV appeared to decrease and be relatively stable in the chronic phase after revascularization, with varying degrees of MTT and TTP shortening. However, there was no significant change in CBF.
ConclusionOur everyday clinical practice experience suggests 9.8 % of consecutive AIS patients present in the 4.5–9 h window and 2.2 % adhere to EXTEND neuroimaging eligibility criteria for IVT. Only 1.3% of AIS is eligible for IVT according to EXTEND neuroimaging and clinical eligibility criteria.

The thalamus is related to language function, and some thalamic stroke cases can cause aphasia . However, most previous cases reporting thalamic damage-induced ipsilateral subcortical diaschisis and aphasia were hemorrhagic stroke [1,2]. Only a few left thalamus infarction cases showed cortical hypoperfusion concerned with the aphasia, but no single-photon emission computed tomography (SPECT) or thalamic nucleus data were available . Thus, aphasia pathology due to cortical hypoperfusion following thalamus infarction, especially with respect to thalamic nuclei, is still unknown.
Conclusions: There is no justification for the use of reperfusion procedures in acute ischaemic stroke in the anterior circulation in patients with initially unfavourable multimodal computed tomography scores. PMID: 31908703 [PubMed]
Conclusion: Some cases with CCI treated with IV-tPA and endovascular intervention were reported, but the treatment strategy should be still discussed multidisciplinary. Especially, the administration of antithrombotic drugs for CCI should be carefully performed because fatal hemorrhage such as cardiac tamponade can occur. PMID: 31893142 [PubMed]
Conclusions: At least 27 pediatric neurocritical care centers use transcranial Doppler during clinical care. In the majority of centers, studies are performed and interpreted by credentialed personnel, and findings are used to guide clinical management. Further studies are needed to standardize these practices.
