Among patients who had had a recent cryptogenic stroke attributed to PFO with an associated atrial septal aneurysm or large interatrial shunt, the rate of stroke recurrence was lower among those assigned to PFO closure combined with antiplatelet therapy than among those assigned to antiplatelet therapy alone. PFO closure was associated with an increased risk of atrial fibrillation. (Funded by the French Ministry of Health; CLOSE ClinicalTrials.gov number, NCT00562289 .).

In this study of patients with symptomatic carotid stenosis of 60% or more, the rates of death and stroke at 1 and 6 months were lower with endarterectomy than with stenting. (ClinicalTrials.gov number, NCT00190398 [ClinicalTrials.gov].).

The development of neuroimaging has allowed clinicians to improve clinicoanatomic correlations in patients with stroke. Anatomic structures are well delineated on MRI, but there is a lack of standardization in their arterial supply. As in our previous study depicting the arterial supply of the brainstem and cerebellum, we present a system of 12 axial sections of the hemispheres depicting the dominant arterial territories, the most important anatomic structures, and Brodmann's areas. The area of variation of the cortical territory of the anterior, middle, and posterior cerebral arteries is also represented. These sections may be used as a practical tool to determine arterial territories on CT or MRI, and may help establish consistent clinicoanatomic correlations in patients with supratentorial stroke.

Campbell, B. C.V. et al. (2019) Penumbral imaging and functional outcome in patients with anterior circulation ischaemic stroke treated with endovascular thrombectomy versus medical therapy: a meta-analysis of individual patient-level data.ABSTRACT Background: CT-perfusion (CTP) and MRI may assist patient selection for endovascular thrombectomy. We aimed to establish whether imaging assessments of ischaemic core and penumbra volumes were associated with functional outcomes and treatment effect.

Patients with a first event of CAD have a very low risk of ischemic events or dissection recurrences. Ischemic events seem rarely to be in relation with chronic arterial lesions.
