Altered cerebral blood flow velocity features in fibromyalgia patients in resting-state conditions
2017
[EN] The aim of this study is to characterize in resting-state conditions the cerebral blood flow velocity (CBFV) signals of fibromyalgia patients. The anterior and middle cerebral arteries of both hemispheres from 15 women with fibromyalgia and 15 healthy women were monitored using Transcranial Doppler (TCD) during a 5-minute eyes-closed resting period. Several signal processing methods based on time, information theory, frequency and time-frequency analyses were used in order to extract different features to characterize the CBFV signals in the different vessels. Main results indicated that, in comparison with control subjects, fibromyalgia patients showed a higher complexity of the envel…
El Doppler de la arteria vertebral como alternativa al Doppler de la arteria cerebral media en el diagnóstico de la restricción del crecimiento fetal
2017
En el feto, la irrigación cerebral proviene fundamentalmente de dos ramas, la arteria vertebral y la arteria carótida interna, que formarán posteriormente el polígono de Willis. Por una parte, la arteria vertebral que es, generalmente, la primera rama y la de mayor tamaño de la arteria subclavia. Ésta irriga toda la parte posterior del cerebro. Por otro lado, la arteria carótida interna irriga la parte anterior del cerebro y es de mayor calibre que la arteria carótida externa, ambas procedentes de la arteria carótida común. La arteria carótida interna y su mayor rama, la arteria cerebral media (ACM), ha sido ampliamente estudiada debido a que está implicada en el mecanismo de “brain-sparing…
