Latin American Consensus Statement for the Use of Contrast-Enhanced Transcranial Ultrasound as a Diagnostic Test for Detection of Right-to-Left Shunt.

Background: The role of patent foramen ovale is a field of debate and current publications have increasing controversies about the patients' management in young undetermined stroke. Work up with echocardiography and transcranial Doppler (TCD) can aid the decision with better anatomical and functional characterization of right-to-left shunt (RLS). Medical and interventional strategy may benefit from this information.

The essential can be invisible to the eyes: the "fogging effect" phenomenon in the subacute stage of ischemic stroke.

Cerebral infarcts can be overlooked or grossly underestimated in the second and third week after an ischemic stroke. We report a patient who presented with a vanishing stroke on a follow-up brain computed tomography scan, a condition known as the "fogging effect" phenomenon.

Trochlear nerve palsy associated with claude bernard-horner syndrome after brainstem stroke.

The association of unilateral trochlear nerve palsy with Claude Bernard-Horner syndrome represents a rare clinical condition. We present the case of a patient with this unusual presentation. The investigation performed implicated cerebrovascular disease as the underlying cause of the condition in this patient.

Clinical features associated with early hospital arrival after acute intracerebral hemorrhage: challenges for new trials.

Background: Early hospital admission followed by correct diagnosis with minimum delay is a prerequisite for successful new interventions in acute intracerebral hemorrhage (ICH). The aim of this study was to evaluate clinical features associated with early hospital arrival in ICH patients and their influence on the outcome.

Methods: Data from all patients arriving within 24 h of the ICH onset were prospectively collected at 2 stroke centers in São Paulo, Brazil.
