A new formula for predicting the position of severe arterial stenosis

KB Abdessalem, RB Saleh - Computer Methods in Biomechanics …, 2017 - Taylor & Francis
Noninvasive location of an occlusion or a severe stenosis in the arterial system is of a great
interest for surgical interventions. Here, we present a new method to determine the location …

Knock signals in ischemic stroke

P Syme - Stroke, 2009 - Am Heart Assoc
I have described a new Transcranial doppler ultrasonography finding “small vessel knock
(SVK)” and have proposed that this is an obstructive arterial signal. 1, 2 SVK is an …
