Paradoxical cerebral embolisation: AN EXPLANATION FOR FAT EMBOLISM SYNDROME
|
Fat embolism occurs following fractures of a long bone or arthroplasty. We investigated whether paradoxical embolisation through a venous-to-arterial circulation shunt (v-a) could lead to cerebral embolisation during elective hip or knee arthroplasty.
Transcranial Doppler ultrasound (TCD), following the intravenous injection of microbubble contrast, identified the presence of a shunt in 41 patients undergoing hip (n=20) or knee (n=21 ) arthroplasty. Intra-operative cerebral embolism wa...
