TCD provides noninvasive monitoring in diverse clinical situations, offering real-time physiological data without increasing patient risks or costs. ...
Since intraoperative strokes are predominantly caused by embolism instead of inefficient hemodynamic circulation, the occurrence of embolic signals may lead to a change of surgical treatment and thereby help to reduce the risk of intraoperative stroke. Emboli detection becomes particularly relevant in vascular surgery, when...
TCD provides real-time information about the blood flow in addition to the hemodynamic changes as a result of various physiological as well as pathological states. TCD can predict stroke by determination of high blood flow velocities, which allows indirect conclusions on stenosis or occlusion....
Because of missing collateralisation beyond the Circle of Willis, occlusions of cerebral arteries result in hypoperfusion or according to size and localisation of the embolus in stroke. Emboli detection is an adequate technical method to narrow the probability of embolic aetiology of stroke....
