Die Nutzung von IT-basierter Informations- und Kommunikationstechnik in der vernetzten medizinischen Versorgung des Schlaganfalls durch den Rettungsdienst ist ein neuer Ansatz in der Schlaganfallversorgung. Im Rahmen der deutschen „Stroke-Angel-Initiative“, die Teil des Forschungsprojektes PerCoMed („pervasive computing in medical care“) ist, stand die(More)
OBJECTIVES The aim of the study was to evaluate the role of anatomical completeness of the circle of Willis for sufficient brain perfusion during unilateral cerebral perfusion and the methodology of the preoperative and intraoperative functional assessments of adequate cross-perfusion. METHODS This prospective observational study included all elective(More)
Die Nutzung moderner Informations- und Telekommunikationstechniken ermöglicht eine Telerehabilitation neurologischer Defizite im häuslichen Umfeld der Patienten. Die aktuelle Studienlage der rehabilitativen Teletherapie zur Verbesserung von Funktions- und Mobilitätseinbußen aufgrund motorischer Defizite nach einem Schlaganfall wird wiedergegeben. Zwei(More)
Elucidation of the dynamic nature of plaque progression has important implications for clinicians. The present study sought to establish an in vivo method for visualizing structural changes in carotid plaques. Three-dimensional reconstruction of parallel two-dimensional gray-scale B-mode ultrasound combined with power-mode examination of 38 carotid artery(More)
Mobile technologies are likely to reveal a high potential to improve the information exchange in medical treatment. Especially in emergency services, the use of these technologies can support the work of the regionally distributed actors. During the last years many projects dealing with innovative mobile systems were started as pilots but in most cases the(More)
Angioplasty and stenting (A/S) provide an alternative for patients with simultaneous severe cardiac and cerebrovascular disease, or with medical illnesses which carry a high perioperative risk. We conducted A/S in 20 high-risk patients (15 males, 5 females, mean age = 64.5 years, range = 49-83 years) with symptomatic (n = 16) and asymptomatic (n = 4)(More)
Power Doppler is a new ultrasound technique based on the visualization of the Doppler power spectrum. In 22 patients with different lesions of brain-supplying vessels the results of power Doppler ultrasound were compared with those of digital subtraction angiography and conventional color Doppler ultrasound. In patients with intracranial high-degree(More)
BACKGROUND AND PURPOSE An understanding of carotid atherosclerosis is important to further our knowledge regarding the etiology of cerebral ischemia, and therefore it is necessary to accurately visualize carotid stenosis. The purpose of the present study was to compare different imaging techniques to determine their advantages and disadvantages in the(More)
The present study was undertaken to assess the clinical use of power Doppler (PD) as a new tool for transcranial vessel imaging. Power Doppler displays the integrated power of the Doppler signal instead of the Doppler frequency shift used in the conventional color flow Doppler (CFD) technique. Twenty-one patients were evaluated who had intracranial(More)
The application of different color-coding techniques in transcranial color-coded duplex sonography (TCCD) was assessed for detection and measurement of the size of intracranial aneurysms. Thirty-two consecutively examined patients with 36 angiographically verified cerebral aneurysms underwent TCCD with color Doppler flow imaging (CDFI), power Doppler(More)
