Carotid and femoral Doppler do not allow the assessment of passive leg raising effects.

Background: The hemodynamic effects of the passive leg raising (PLR) test must be assessed through a direct measurement of cardiac index (CI). We tested whether changes in Doppler common carotid blood flow (CBF) and common femoral artery blood flow (FBF) could detect a positive PLR test (increase in CI ≥ 10%). We also tested whether CBF and FBF changes could track simultaneous changes in CI during PLR and volume expansion.

Cortical border-zone infarcts: clinical features, causes and outcome.

Objective: To report the clinical features, causes and outcome of cerebral cortical border-zone infarcts BZI (C-BZI).

Methods: The authors prospectively included patients with MRI-confirmed C-BZI among individuals consecutively admitted in Stroke Unit.

Results: Forty-five patients presented C-BZI out of 589 with MRI-confirmed cerebral infarcts (7.

Watershed infarctions are more prone than other cortical infarcts to cause early-onset seizures.

Background: Early-onset seizures(ESs) have been reported in 2% to 6% of strokes. Most previous studies have been retrospective and did not systematically perform cerebral magnetic resonance imaging (MRI).

Objective: To determine the prevalence and determinants of ESs in a prospective cohort.
