Case ReportsAcute foot drop syndrome mimicking peroneal nerve injury: an atypical presentation of ischemic stroke.
Foot drop syndrome is a frequent neurologic condition usually caused by peroneal nerve damage. On rare occasions, foot drop may present as the single neurologic manifestation of intracranial lesions. ⋯ Three months later, his motor deficit had completely improved (modified Rankin scale score = 0). To our knowledge, this is the second report of sudden isolated foot drop caused by a cortical infarction.

Tracheostomy after severe ischemic stroke: a population-based study.
Stroke can result in varying degrees of respiratory failure. Some patients require tracheostomy in order to facilitate weaning from mechanical ventilation, long-term airway protection, or a combination of the two. Little is known about the rate and predictors of this outcome in patients with severe stroke. We aim to determine the rate of tracheostomy after severe ischemic stroke. ⋯ Tracheostomy is common after decompressive craniectomy and is strongly associated with the development of pneumonia. Given its impact on patient function and potentially modifiable associated factors, tracheostomy may warrant further study as an important patient-centered outcome among patients with stroke.

Case ReportsLateral medullary stroke in patient with granulomatous polyangiitis.
Granulomatous polyangiitis (GPA), also known as Wegener granulomatosis, is a systemic antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis that infrequently affects the central nervous system. We report a 41-year-old man with lateral medullary infarction who developed rapidly progressive renal failure. ⋯ He had resolution of his neurologic deficits and improvement in renal function. This case report highlights the importance to consider GPA vasculitis in the differential diagnosis of stroke in patients with development of acute kidney injury.

Clinical spectrum of artery of Percheron infarct: clinical-radiological correlations.
The occlusion of the artery of Percheron results in bilateral thalamic and mesencephalic infarctions. In this series, we attempted to classify the subtypes of clinical presentations and long-term prognosis with regards to radiological patterns. ⋯ Our findings suggest that it is possible to identify clinical and radiological subgroups of Percheron artery infarct. The long-term follow-up outcome is generally good, except in cases with midbrain involvement.

Validation of ultrasound parameters to assess collateral flow via ophthalmic artery in internal carotid artery occlusion.
This study aimed to characterize the flow patterns using ultrasound (US) in the external carotid artery (ECA) in patients with total occlusion of internal carotid artery (ICA) and characterize collateral retrograde flow through the ophthalmic artery (OA, secondary collateral, internalization). This study was performed on 45 patients who were retrospectively selected with total occlusion of the ICA, who underwent digital subtraction angiography (DSA), magnetic resonance angiography (MRA), and US (43 men; mean age 68.1 ± 7.9 years). Collateral retrograde flow and collateral flow through the circle of Willis (primary collateral) were determined by DSA and MRA. ⋯ ECA ED velocity was significantly higher, and PI and PTI were significantly lower with retrograde flow through OA than without (P < .05). According to receiver operating characteristic analysis, PTI was the most highly correlated ultrasonologic parameter with internalization (cutoff value, .94; sensitivity, 92.6%; specificity, 94.5%). Using PTI was discriminative to determine internalization of ECA because a collateral pathway through OA in cases of ICA occlusion had less primary collateral pathways.
