The study attempts to identify notable factors predicting poor outcome, death, and intracranial hemorrhage in patients with acute ischemic stroke undergoing mechanical thrombectomy with stent retriever. These data could be useful to improve the selection of patients for thrombectomy. ⋯ Absolute baseline ASPECT score reflects early symptomatic hemorrhage risk and functional outcome at 3 months. Thrombus length measured on MRI play an important role on functional outcome at 3 months after thrombectomy. Further analyses are needed to determine its importance in the selection of patients for mechanical thrombectomy.

The aim of this study was to examine reliability and reproducibility of volumetric perfusion deficit assessment in patients with acute ischemic stroke who underwent recently introduced whole-brain CT perfusion (WB-CTP). ⋯ Volumetric assessment in WB-CTP is reliable and reproducible. It might serve for a more accurate assessment of stroke outcome prognosis and definition of flow-volume mismatch. Time to drain showed the highest agreement and therefore might be an interesting parameter to define tissue at risk.

Comparative Study
Whole-brain CT digital subtraction angiography of cerebral dural arteriovenous fistula using 320-detector row CT.
The purpose of this study was to evaluate the usefulness of CT digital subtraction angiography (CTDSA) by using 320-detector row CT in the diagnosis and classification of cerebral dural arteriovenous fistula (dAVF) and comparing it with DSA as the standard reference. ⋯ Although CTDSA is limited in temporal and spatial resolution in comparison with DSA, it is an effective non-invasive tool for the detection and classification of dAVF.
