Introduction
Complications of fat grafting by means of injection may lead to unwanted passage of substrate into vessel lumens resulting in catastrophic complications. Likewise, a similar trend of complications is observed with non-autologous fillers regardless of an almost generalized use of blunt cannulas, the latter being implicated in the majority of serious vascular complications of hyaluronic acid injection. This report is the product of investigation to review all cases that underwent an original technique of fat injection: “The smart fat injection” during the cannula’s brisk withdrawal technique. The aim of this research was to document the safety of this technique by searching if fat embolism had occurred and if yes, its incidence in this group of fat injection surgeries.
Method
This retrospective review included 3039 patients who underwent the smart fat injection at the facial or corporeal level between 2001 and 2019. The study focused on the search for complications linked to fat yet also cruorical embolism, as the latter may resemble the clinical symptoms of fat embolism.
Results
The assessment of the 3039 patients who underwent the smart fat injection during cannula’s brisk withdrawal, resulted in none presenting clinically detectable fat or a cruorical embolism.
Conclusion
This report documents the safety of the smart fat injection developed over a period of 22 years. It further explains the rationale of the technique for avoiding fat embolism while simultaneously enhancing fat take. This technique should not be implemented without appropriate in vitro training.
