Transcranial Color‐Coded Duplex Sonography in Large‐Vessel Vasculitis Compatible With Takayasu Arteritis Presenting Intracranial Involvement and Vertebrobasilar Dolichoectasia: A Case Report

Journal of Clinical Ultrasound, EarlyView.
This case illustrates sequential intracranial occlusions in large‐vessel vasculitis compatible with Takayasu arteritis preserving perfusion through robust collateral pathways. Transcranial color‐coded duplex sonography identified characteristic blunted flow patterns and focal turbulence, underscoring its value in detecting hemodynamic compromise beyond

Análise da capacidade reactiva da circulação intracerebral pelo efeito do CO2. Um método de fácil execução.

Acta Médica Portuguesa, 1998
Maintenance of cerebral perfusion pressure is a prerequisite for the prevention of cerebral ischaemia. Physiological fluctuations in systemic perfusion pressure are compensated by cerebrovascular autoregulation.

Validation of Aortic Blood Flow Simulations During Extracorporeal Circulation Using Phase Contrast Magnetic Resonance Imaging

Artificial Organs, EarlyView.
This is the first study assessing in vivo blood flow profiles during extracorporeal circulation (ECC) scenarios. Magnetic resonance imaging data served for the calibration of computational fluid dynamics algorithms, enabling accurate replication of the hemodynamic conditions.

Mechanisms of Cough Syncope as Evaluated by the Valsalva Maneuver

Kaohsiung Journal of Medical Sciences, 2007
Transcranial Doppler is often employed for the assessment of cerebral hemodynamics. The study by Chao et al in the February 2007 issue of the journal raises some important issues regarding the understanding of the mechanisms involved in cough syncope. We

Ischaemic stroke and 5‐fluorouracil or capecitabine: A systematic review and meta‐analysis of harms and a retrospective study of the WHO pharmacovigilance database

British Journal of Pharmacology, EarlyView.
Abstract Aim Fluoropyrimidines, including 5‐fluorouracil (5‐FU) and capecitabine, are cornerstone antineoplastic agents for cancer. Case reports suggest that these drugs may be associated with an under‐recognised risk of ischaemic stroke or transient ischaemic attack (TIA).

Research and Medical Transcranial Doppler System

Archives of Acoustics, 2016
A new ultrasound digital transcranial Doppler system (digiTDS) is introduced. The digiTDS enables diagnosis of intracranial vessels which are rather difficult to penetrate for standard systems.

Project Sickle Cure: A Prospective, International Observational Study of Hematopoietic Cell Transplantation for Sickle Cell Disease

European Journal of Haematology, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a chronic and life‐limiting hemoglobin and systemic vascular disease. While over 1000 people have undergone hematopoietic cell transplantation (HCT) over the last 40 years, long‐term disease‐specific and health‐related quality of life data are lacking.
