[Subclavian steal-carotid recovery phenomenon - "old school" surgical procedure]. / Subclavian-steal recovery carotid fenomén " old school" chirurgické resení.

Subclavian steal-carotid recovery phenomenon appears to be related to the occlusion of the truncus brachiocephalicus and can be a rare cause of neurological deficit. In this syndrome, the right common carotid artery and right subclavian artery are filled with retrograde flow from the ipsilateral vertebral artery. We present a patient with this type of steal syndrome managed by a classical surgical procedure for stent reocclusion in the truncus brachiocephalicus.Key words: steal phenomenon endarterectomy truncus brachiocephalicus.

Day activity centres - work for people with intellectual disabilities: a norwegian perspective.

BACKGROUND: Although there is a broad political consensus in Norway that the government should uphold the principles of "full employment" and "work for all", the majority of people with intellectual disabilities in Norway spend their days in segregated work arrangements or at day activity centres. OBJECTIVE: The aim of the current study was to explore what constitutes work and work roles for people with intellectual disabilities and severely limited verbal communication abilities who attend a day activity centre. METHOD: A qualitative ethnographic research design was adopted, and the data were gathered through observing the participants and through conducting conversational interviews with the staff members and the participants with intellectual disabilities. Data were analysed with a hermeneutic approach. RESULTS: The findings showed that even though participants with intellectual disabilities engaged in specific work roles at the day activity centre, these work roles did not constitute work as it is ordinarily conceptualised and valued in society. CONCLUSION: Despite the very real enjoyment that the participants derive from participating in organised occupation, the work that they do has little status or value, and the activity centre itself is not a satisfactory workplace for people with intellectual disabilities.

Dissection of thoracic aorta. Combined surgical and endovascular treatment.

In our case report, we would like to present combined surgical and endovascular treatment of type A aortic dissection as a modern and definite solution of this life-threatening disease.

Particle image velocimetry measurement in the model of vascular anastomosis.

Neointimal hyperplasia is the most common complication of all forms of arterial reconstructions. This response of the vascular wall to injury is influenced by many factors, especially, but not limited to, by the hemodynamic profile in the area of vascular anastomosis and in its close proximity. To eliminate this negative influence of hemodynamics on progression of neointimal hyperplasia, we tried to develop anastomosis with optimal hemodynamic parameters. In our experimental study we used Particle Image Velocimetry measurement and 3D blood flow simulation for studying flow characteristics for different length and angles of anastomoses. Based on our experimental studies and numerical simulations we believe that anastomosis with smaller angle demonstrates better hemodynamic parameters, optimal angle being less than 30 dg. Length of anastomosis in this smaller angle anastomosis is app. 2-2.5 of native vessel diameter.
