    • Accuracy of power mode transcranial Doppler in the diagnosis of brain death 
      Brunser, Alejandro M.; Lavados Germain, Pablo Manuel; Cárcamo, Daniel A.; Hoppe, Arnold; Olavarría, Verónica V.; López, Javiera; Muñoz, Paula; Palacios Rivas, Rodrigo (Elsevier (Singapore) Pte Ltd, 2015)
      © 2014.Background: The diagnosis of brain death (BD) is complex. For this reason, we aimed to evaluate the accuracy of power mode transcranial Doppler (PMD-TCD) in diagnosing BD. Patients and methods: Patients admitted to ...
    • Additional information given to a multimodal imaging stroke protocol by transcranial doppler ultrasound in ... 
      Brunser, Alejandro M.; Lavados Germain, Pablo Manuel; Cárcamo, Daniel A.; Hoppe, Arnold; Olavarría, Verónica; Díaz, Violeta; Rivas, Rodrigo (2010)
      Background: Transcranial Doppler (TCD) ultrasound can demonstrate dynamic information. We aimed to evaluate whether TCD generates useful additional information in the emergency room after a multimodal stroke imaging ...
    • Diffusion-weighted imaging determinants for acute ischemic stroke diagnosis in the emergency room 
      Brunser, Alejandro M.; Cavada Chacón, Gabriel; Muñoz Venturelli, Paula; Olavarría, Verónica; Rojo, Alexis; Almeida, Juan; Díaz, Violeta; Hoppe, Arnold; Lavados Germain, Pablo Manuel (Springer, 2018-07)
      The aim of this study was to investigate the clinical-radiological determinants of diffusion-weighted image (DWI) abnormalities in patients with suspected acute ischemic stroke (AIS) seen at the emergency room (ER). ...
    • Head position and cerebral blood flow velocity in acute ischemic stroke: A systematic review and meta-analysis 
      Olavarría, Verónica V.; Arima, Hisatomi; Anderson, Craig S.; Brunser, Alejandro M.; Muñoz-Venturelli, Paula; Heritier, Stephane; Lavados Germain, Pablo Manuel (S. Karger AG, 2014)
      Background: Patients with acute ischemic stroke (AIS) have impaired vasomotor reactivity, especially in the affected cerebral hemisphere, such that they may depend directly on systemic blood pressure to maintain perfusion ...
    • Reliability of hand held transcranial doppler with m - mode ultrasound in middle cerebral artery measurement 
      Muñoz Venturelli, Paula; Brunser, Alejandro M.; Gaete, Javier; Illanes, Sergio; López, Javiera; Olavarria, Veronica V.; Reccius, Andrés; Brinck, Pablo; González, Francisca; Cavada Chacón, Gabriel; Lavados Germain, Pablo Manuel (Elsevier, 2017)
      Purpose: To determine the intra-and interrater agreement of mean flow velocity (MFV) and pulsatility index (PI) measurement in middle cerebral arteries, assessed by transcranial Doppler (TCD) with M-mode. Methods: ...
    • The Role of TCD in the Evaluation of Acute Stroke 
      Brunser, Alejandro M.; Mansilla, Eloy; Hoppe, Arnold; Olavarría, Verónica; Sujima, Emi; Lavados Germain, Pablo Manuel (2016)
      BACKGROUND: The additional information that transcranial Doppler (TCD) can provide as part of a multimodal imaging stroke protocol in the setting of hyper acute strokes has not been evaluated. METHODS: Consecutive ...
    • Yield of Echocardiography in the Evaluation of Cerebral Ischemic Events: A Single Center Cohort Study 
      Brunser, Alejandro M.; Ibañez-Arenas, Rodrigo; Larico, Martin; Mansilla, Eloy; Almeida, Juan; Olavarría, Verónica V.; Muñoz, Paula; Rojo, Alexis; Cavada, Gabriel; Lavados Germain, Pablo Manuel (W.B. Saunders, 2019)
      © 2018Background: Echocardiography (ECO) is frequently used as a screening test in patients with acute ischemic brain disease. We aimed to evaluate the additional information and therapeutic impact resulting from ECO in ...
