The Usage of Intravenous Tranexamic Acid in Reduction Mammaplasty Safely Reduces Hematoma Rates.

Background: Bleeding complications are not uncommon after breast reduction surgery, and recently, tranexamic acid (TXA) as an antifibrinolytic agent has been used in various surgical specialties as a way to minimizes such adverse outcomes. We elected to evaluate the effectiveness of intravenous (IV) intraoperative TXA in reduction mammoplasty patients.

Methods: This is a retrospective chart review of clinical charts of all patients who received reduction mammoplasty by a single surgeon at Emory University Hospital or its affiliated Aesthetic Center from January 1, 2020, to March 1, 2022. Seventy-four consecutive breast reduction patients received 1-g IV TXA intraoperatively compared with 117 consecutive controls. The outcome of interest included 30-day postoperative bleeding complications.

Results: There was no significant difference in age ( P = 0.92), body mass index ( P = 0.98), percentage of smokers ( P = 0.56), operating time ( P = 0.87), estimated blood loss ( P = 0.90), or weight removed ( P = 0.98) between patients in each arm. There were 19 bleeding events (16.2%) in the non-TXA arm compared with 1 bleeding event (1.4%) in the TXA arm ( P = 0.0143). Of the 19, 6 (5.1%) were major events, and 13 were minor events (11.1%); the only bleeding event in the TXA arm was minor. Number needed to treat all bleeding events with use of TXA was 7, and the number needed to treat minor hematomas was 11. There was no significant difference in the rate of seroma, wound healing complications, infection, or nipple necrosis between the 2 arms ( P > 0.05).

Conclusions: The use of IV TXA is a safe and effective way to reduce hematoma rates in patients receiving reduction mammoplasty.
