Paradoxical Cerebral Fat Embolism in Revision Hip Surgery
نویسندگان
چکیده
The incidence of clinical fat embolism syndrome (FES) is low (<1%) whilst fat embolism (FE) of marrow fat appears to occur more often (Mellor and Soni (2001)). Paradoxical brain FE may occur in patients undergoing hip orthopedic surgery who have an undocumented patent foramen ovale (PFO). We report a case of an eighty-year-old male patient, who underwent a scheduled revision hip surgery suffering a paradoxical cerebral FE.

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 pati...

متن کاملIntraoperative cerebral arterial embolization during total hip arthroplasty.
BACKGROUND Fat embolism to the pulmonary circulation is known to occur during total hip arthroplasty, especially during insertion of a cemented femoral component. Fat and air bubbles may enter the systemic circulation via a patent foramen ovale or through pulmonary circulation. METHODS To determine whether microemboli to the brain were occurring during total hip arthroplasty, 23 patients unde...
متن کاملParadoxical embolism associated with oral contraceptives: an underdiagnosed lesion?
A case of cerebral embolism is described in which paradoxical features have been proved clinically, and which may explain some hitherto unaccountable reported cases, and suggests the value of prospective studies. A successful outcome of such a proved case, associated with oral contraceptives, does not appear to have been reported previously.
