The Use of Tranexamic Acid in Breast Reduction and Abdominoplasty: A Review of a Multicenter Federated Electronic Health Record Database.

Background: Tranexamic acid (TXA), a fibrinolysis inhibitor, is widely used in various surgical fields to minimize blood loss. However, its efficacy and safety in plastic surgery, especially in reduction mammaplasty and abdominoplasty, remain underexplored. This study investigates the utility of intravenous (IV) TXA in these procedures, focusing on reducing postoperative complications and evaluating its safety in the context of venous thromboembolism (VTE).

Objectives: To evaluate the efficacy and safety of TXA in reduction mammaplasty and abdominoplasty.

Methods: Using data from the TriNetX LLC (Cambridge, MA) National Health Research Network database, this retrospective study compared adult patients undergoing reduction mammaplasty or abdominoplasty who received intraoperative IV TXA against those who did not. Primary outcomes included postoperative seroma and hematoma incidences, whereas secondary outcomes assessed the necessity for procedural drainage and the occurrence of VTE within 1-year postsurgery.

Results: No significant differences in the rates or risks of hematoma, seroma, or the need for procedural drainage between patients administered IV TXA and those who were not, for both reduction mammaplasty and abdominoplasty. Additionally, IV TXA did not increase the risk of VTE in either patient group.

Conclusions: IV TXA application in reduction mammaplasty and abdominoplasty does not provide added benefits in reducing postoperative complications such as seroma, hematoma, or the necessity for procedural drainage. Furthermore, it does not alter the risk of thromboembolic events. These findings highlight the need for further research, particularly through randomized control trials, to understand TXA's efficacy in plastic surgery.
