Reversible posterior leukoencephalopathy syndrome (PRES) is a neurological disorder characterized by signs of posterior cerebral edema upon radiographic examination. ⋯ Reversible posterior leukoencephalopathy may develop in patients who have renal insufficiency or hypertension or who are immunosuppressed. This syndrome should be recognized immediately and trigger agents can be discontinued to prevent long-term sequelae.

Traumatic injury of peripheral nerves is a worldwide problem and can result in significant disability. Management of peripheral nerve injuries (PNIs) requires accurate localization and the assessment of severity of the lesion. ⋯ This study can serve as a guide to determine the epidemiology and classification of traumatic peripheral and plexus injuries.

The purpose of this study was to assess the clinical value of indocyanine green angiography (ICG) in intracranial aneurysm surgery by comparing the findings with postoperative angiographic results. ⋯ ICG angiography is a simple, reliable and cost-effective method. It provides real-time information in detecting the patency of parent, branching, perforating arteries and residual aneurysm. This technique may be a useful adjunct to improve the quality of intracranial aneurysm surgery.

Vasoactive drug alprostadil improves microcirculation and can be effective in treating disorders of peripheral nerves. Vascular endothelial growth factor (VEGF) has been shown to have protective action in cerebral ischemia, disorders of spinal cord, and also peripheral nerves. However, the mechanism of action of VEGF in peripheral nerve injuries is uncertain. ⋯ The vasoactive agent alprostadil may reduce the pathological lesion of peripheral nerves and improve the rehabilitation of the neural function, which may relate to upregulation of the expression of VEGF, following crush injury to the peripheral nerves.
