I new interest in intra-operative monitoring during enarterectomy is re-visited. I will post a couple of interesting links.

"I would like to share with you a few words about the use of a-mode ultrasound (echoencephalography) at Bowman Gray. My training began several years before the ready availability of computed tomography in the emergency center setting. An early application of ultrasound was for rapid screening of trauma and stroke patients for intracranial mass lesions. The underlying concept was that a-mode ultrasound could be used to identify structures normally located in the midline of the brain such as the third ventricle and falx cerebri."
The second reference is from the ARDMS newsletter.
" New techniques for detecting harmful blood clots and air bubbles in arteriesNew techniques for detecting emboli have played a major role in dramatically reducing stroke rates after carotid edarterectomy.New techniques for detecting emboli (harmful blood clots/air bubbles in arteries) developed at the University of Leicester have played a major role in dramatically reducing stroke rates after carotid endarterectomy. This is an operation designed to remove narrowings in the main arteries supplying the brain before they can cause a stroke."
