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...
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....
Monitoring of sufficient brain perfusion is an essential part of anesthesiology and intensive care medicine. Transcranial Doppler Sonography is a non-invasive method, which provides real-time information about the cerebral haemodynamical situation, for instance...
Patent Foramen Ovale (PFO) causing Right to Left Shunt (RLS) can be detected by TCD PFO-Test. RLS are direct connections between right (pulmonary) and left (systemic) circulation. By this connection blood can cross to the other circulation without passing pulmonary capillaries....
SARS-CoV-2 infection can be particularly dangerous in patients whose vascular function is already impaired by pre-existing conditions. This explains the typical clinical picture by causing circulatory disorders in the heart, as well as pulmonary embolism and vascular occlusions....
