Infos

Ultrasound enables us to monitor the cardiovascular system and brain responses to treatment in real time; a genuine blessing on the route to more effective stroke therapies, and an invaluable tool with which to tailor treatment when available evidence is meagre. Ultrasound is a vital observational tool, yet a probe needs a scientist to point it in the right direction and a skilled physician to synthesise scientific data with practical management strategies.

This book, intended for clinicians who are eager to learn and prepared to observe, focusses on the examination of stroke patients, the interpretation of ultrasound studies, and the application of cerebrovascular ultrasound to management and treatment strategies. Produced by an international team of contributors and edited at the University of Texas, one of the major world centres in stroke research, it is a practical volume that can be used by beginners to learn the principles of ultrasound testing, by advanced users to learn differential diagnosis, and by clinicians (non-sonographers) who treat stroke patients. The latter will gain knowledge on how to apply ultrasound, and what to expect from it in terms of clinical decision making and treatment selection.

"Cerebrovascular Ultrasound in Stroke prevention andTreatment" Edited by Andrei V. Alexandrov

This book has been produced by an international team ofcontributors, edited at the University of Texas and is aimed atthree types of individuals: beginners to learn the basics ofultrasound testing, advanced users to learn differential diagnosisand clinicians involved in treating stroke patients. The text ispacked full of useful practical information and has excellentillustrations and TCD images. However, the content is not basic andbeginners wishing to start TCD would be advised to read simplertexts prior to this book. It is divided into five parts: Part I-Howto perform ultrasound tests covers both extracranial andintracranial ultrasound examination with an emphasis onstandardisation for carotid duplex. The techniques for carrying outsingle-gated spectra (TCD), power-motion Doppler (M-mode) andtranscranial colour duplex imaging (TCCS) are outlined in a simpleand clear manner. The advantages of M-mode (easier window-finding)and TCCS (identifying anomalies of the circle of Willis) for thebeginner are emphasised but the caveat for both M-mode and TCCS isspectral resolution and it is acknowledged that experiencedoperators will still use single-gated TCD. Part II-Haemodynamicprinciples is a "heavy" section but will be ofparticular interest to anyone working in the intensivecare/surgical setting. The chapter on practical models of cerebralhaemodynamics importantly emphasises spectral waveform recognitionrather than the usual emphasis on velocity. Part III-Criteria forinterpretation. is an excellent section covering diagnostic andvalidation criteria for carotid stenosis, carotid and vertebralartery dissection and occlusion, intracerebral arterial vasospasm,embolism detection, with a good description of the TIBI ultrasoundclassification for large vessel occlusion. Part IV-Ultrasoundin stroke prevention and treatment covers ultrasound findings ofspecific diseases including sickle cell disease, cardiovascularrisk, secondary stroke prevention, acute ischaemic stroke,subarachnoid haemorrhage. The chapter on ischaemic stroke discussesthe potential therapeutic use of TCD and is well worth reading.Part V-Select clinical applications and clinical vignettesincludes an interesting collection of anecdotal vascular casescovering areas, which can give diagnostic difficulty. The excitingparts of this book have to be the emphasis on the potentialtherapeutic use of diagnostic TCD and the focus on waveformanalysis rather than velocity measurements. This opens up TCD as abedside tool, which will hopefully mean that more clinicians willstart using this powerful technique.
