The early recurrence of neurological symptoms (NR) after urgent aggressive best medical therapy (BMT) in symptomatic carotid stenosis is not well documented. ⋯ Urgent aggressive BMT after index-event is associated with a significant reduction in the risk of early NR in CEA candidates. The early risk of recurrent stroke in patients with symptomatic significant carotid stenosis is dramatically reduced after urgent aggressive BMT in specialised stroke clinics.

Cerebral ischemia is a leading cause of disability worldwide and no other effective therapy has been validated to date than intravenous thrombolysis. In this context, many preclinical models have been developed and recent advances in preclinical imaging represent promising tools. Thus, we proposed here to characterize in vivo time profiles of cerebral blood flow, blood-brain barrier disruption and apoptosis following a transient middle cerebral artery occlusion in rats using SPECT/CT imaging. ⋯ Using SPECT/CT imaging, we showed that after transient middle cerebral artery occlusion in rat there was a sustained decrease in cerebral blood flow followed by blood-brain barrier disruption preceding meanwhile apoptosis. Rodent SPECT/CT imaging of cerebral blood flow, blood-brain barrier disruption and apoptosis appears to be an efficient tool for evaluating neuroprotective drugs and regenerative therapies against cerebral ischemia and time-windows for therapeutic intervention.

Randomized Controlled Trial Multicenter Study Comparative Study
Acute Stroke or Transient Ischemic Attack Treated with Aspirin or Ticagrelor and Patient Outcomes (SOCRATES) trial: rationale and design.
The risk of recurrent ischemia is high in the acute period after ischemic stroke and transient ischemic attack. Aspirin is recommended by guidelines for this indication, but more intensive antiplatelet therapy may be justified. ⋯ The SOCRATES trial fulfills an important clinical need by evaluating a potent antiplatelet agent as a superior alternative to current standard of care in patients presenting acutely with ischemic stroke or transient ischemic attack.

Intravenous thrombolysis is considered to be the standard specific reperfusion therapy in acute ischemic stroke in both anterior and posterior cerebral circulation. ⋯ Our study suggests that posterior circulation stroke is associated with a lower risk of intracranial hemorrhage than anterior circulation stroke is.
