Fat embolism in liposuction and intramuscular grafts in rabbits

purpose: to evaluate the effects of fat embolism in organs such as lung and liver. methods: twenty rabbits underwent autologous intramuscular fat grafting in the right thigh after liposuction. the groups were determined according to the postoperative day that occurred in euthanasia: 60, 90 and 120 day. then, lung and liver were excised and sent to the histopathology laboratory for analysis in search of late injury secondary to a prior event of fat embolism in the tissues. results: the results showed a change in the macroscopic sample with discoloration of the liver tissue heterogeneously. there were no changes consistent with embolic effect under the microscope. conclusion: the option of performing a technique of fat grafting with a less traumatic surgical procedure can be considered protective against embolic events, with no impact to late embolic events on the tissues.
