Cím:	The role of extracranial ultrasound in the prevention of stroke based on the new guidelines / Brigitta Léránt, László Csiba

Megjegyzések:	Extracranial ultrasonography is recommended to use as a baseline non-invasive method in the initial evaluation of either asymptomatic or symptomatic patients to define the possible stenosis on carotid artery. The latest 2011 guidelines specify the sequence of examinations with certain classification of recommendations and level of evidence. Carotid duplex ultrasonography plays an important role both in primary and secondary prevention of stroke and the results found determine the use of further investigations and management of patients with extracranial carotid and vertebral artery disease. In case of diagnostic uncertainty other brain imaging methods, like computed tomography angiography, magnetic resonance angiography and catheter-based angiography can be chosen to assess vascular lesions. Carotid duplex ultrasound serves not only diagnostic purposes but can also be useful in the follow up processes. It is widely used for control examinations after revascularization procedures of the carotid or vertebrobasilar arteries. By the establishment of indications of revascularization procedures degree of carotid stenosis is a major factor which therefore requires accuracy of the assessment. Carotid duplex ultrasound has some difficulties in this question. This diagnostic uncertainty is tried to be solved by improving the criteria system of stenosis grading in internal carotid artery. The aim of this article is to give an overview about the importance and role of extracranial duplex ultrasonography in stroke prevention based on the latest guidelines.

Cím:	Morphological, hemodynamic and stiffness changes in arteries of young smokers / Brigitta Léránt, Christina Straesser, Réka Katalin Kovács, László Oláh, László Kardos, László Csiba
Dátum:	2012
ISSN:	2211-968X
Megjegyzések:	Aim The aim of our investigations was to detect the acute and chronic effects of cigarette smoking on arterial wall thickness and stiffness in young, healthy volunteers. We also performed a one-year follow-up to define the possible changes. Subjects We recruited 25 non-smoking and 25 smoking university students aged 19-33. Exclusion criteria were any known diseases, abnormally high cholesterol levels and body mass index (BMI) above 30 kg/m2. Methods We defined the intima-media thickness on both common carotid arteries by using B-mode ultrasonography and we measured the hemodynamic and stiffness parameters with the help of arteriograph. In case of smokers we also investigated the acute effects after smoking one cigarette. In the follow-up study we measured 15 non-smokers and 13 smokers again. Results In the smoking group morphological, stiffness and hemodynamic parameters showed significantly higher values compared to non-smokers. Concerning the acute effects we detected a significant increase in stiffness and hemodynamic parameters after smoking one cigarette. Gender differences were also found in the smoking group. Unadjusted to age, gender and smoking status there was a significant correlation between intima-media thickness and pulse wave velocity. We could not find any progression in smokers after one year, while there was an improvement in intima-media thickness and augmentation index in non-smokers. Conclusion Early atherosclerotic processes due to smoking can be detected even at a young age, in healthy university students. One year regular smoking does not result in detectable changes.
