      Lange, Marcos C.; Zétola, Viviane H. F.; Miranda-Alves, Maramélia [UNIFESP]; Moro, Carla H. C.; Silvado, Carlos E.; Rodrigues, Daniela L. G. [UNIFESP]; Gregorio, Edilene Guiotti Di; Silva, Gisele Sampaio [UNIFESP]; Oliveira-Filho, Jamary; Perdatella, Marco T. A.; Pontes-Neto, Octávio M.; Fábio, Soraia R. C.; Avelar, Wagner M.; Freitas, Gabriel R. de (Academia Brasileira de Neurologia - ABNEURO, 2012-05-01)
      Neurosonological studies, specifically transcranial Doppler (TCD) and transcranial color-coded duplex (TCCD), have high level of specificity and sensitivity and they are used as complementary tests for the diagnosis of ...

    • Cerebral vasomotor reactivity in reversible cerebral vasoconstriction syndrome 

      Topcuoglu, Mehmet Akif; Chan, Suk-tak; Silva, Gisele Sampaio [UNIFESP]; Smith, Eric Edward; Kwong, Kenneth K.; Singhal, Aneesh Bhim (Sage Publications Ltd, 2017)
      Background: Altered cerebrovascular tone is implicated in reversible cerebral vasoconstriction syndrome (RCVS). We evaluated vasomotor reactivity using bedside transcranial Doppler in RCVS patients. Methods: In this ...

    • Changes in Transcranial Doppler Flow Velocities in Children with Sickle Cell Disease: The Impact of Hydroxyurea Therapy 

      Adegoke, Samuel Ademola [UNIFESP]; Macedo-Campos, Rejane de Souza [UNIFESP]; Pellegrini Braga, Josefina Aparecida [UNIFESP]; Figueiredo, Maria Stella [UNIFESP]; Silva, Gisele Sampaio [UNIFESP] (Elsevier Science Bv, 2018)
      Background and Objectives: Hydroxyurea (HU) was recently described as a substitute for chronic transfusion for children with sickle cell disease (SCD) and abnormal transcranial Doppler (TCD) velocities who have received ...

    • Detection of Cerebral Vasculopathy by Transcranial Doppler in Children With Neurofibromatosis Type 1 

      Sagica Fernandes Paschoal, Joelma Karin [UNIFESP]; Paschoal, Fernando Mendes, Jr.; de Lima, Fernanda Teresa [UNIFESP]; Pinho, Ricardo Silva [UNIFESP]; Pereira Vilanova, Luiz Celso [UNIFESP]; Bor-Seng-Shu, Edson; Masruha, Marcelo Rodrigues [UNIFESP] (Sage Publications Inc, 2016)
      Neurofibromatosis type 1 is characterized by nerve sheath neurofibromas associated with a number of additional clinical features, including cerebrovascular disease. The aim of this study was to use transcranial Doppler as ...

    • Is the number of microembolic signals related to neurologic outcome in coronary bypass surgery? 

      Malheiros, Suzana Maria Fleury [UNIFESP]; Massaro, Ayrton Roberto; Gabbai, Alberto Alain [UNIFESP]; Pessa, Clodualdo J. N. [UNIFESP]; Gerola, Luís Roberto [UNIFESP]; Branco, João Nelson Rodrigues [UNIFESP]; Lira Filho, Edgar Bezerra; Christofalo, Dejaldo Marcos de Jesus; Federico, Darwin; Carvalho, Antonio Carlos [UNIFESP]; Buffolo, Enio [UNIFESP] (Academia Brasileira de Neurologia - ABNEURO, 2001-03-01)
      Coronary artery bypass surgery (CABG) without cardiopulmonary bypass (CPB) may potentially reduce the number of microembolic signals (MES) associated with aortic manipulation or generated by the pump circuit, resulting in ...

    • Migraine-mimicking headache and sickle cell disease: a transcranial Doppler study 

      Silva, G. S.; Vicari, P.; Figueiredo, M. S.; Junior, H. C.; Idagawa, M. H.; Massaro, A. R. (Sage Publications Ltd, 2006-06-01)
      Headache occurs in sickle cell disease (SCD), but its characteristics and frequency have not previously been studied. Our aim was to study patterns of headache in adults with SCD and to correlate its presence with blood ...
