The aim of this retrospective study was to compare intracranial arterial stenosis in patients with stroke using 3 different methods: transcranial color-coded duplex sonography, computed tomographic (CT) angiography, and digital subtraction angiography in a common clinical practice. ⋯ Moderate agreement was found between CT angiography, transcranial color-coded sonography, and digital subtraction angiography in the evaluation of intracranial stenosis. Computed tomographic angiography and digital subtraction angiography are sufficient for assessment of the diagnosis.

Ultrasound guidance is associated with improved efficiency and success of peripheral nerve blockade and a decreased incidence of vascular puncture, making these interventions safer. Patients with peripheral nerve blocks report decreased pain and increased satisfaction scores. We present the development of a mobile ultrasound-guided block service that allows for the safe and efficient placement of nerve blocks and perineural catheters at the nontraditional location of the patient's bedside and in the emergency department.
