Topical Tranexamic Acid in Breast Reconstruction: A Double-Blind Randomized Controlled Trial

Abstract

BACKGROUND: Excess fluid accumulation (seroma/hematoma) around the breast implant after reconstruction can lead to significant complications. Topical administration of tranexamic acid (TXA) may reduce fluid accumulation and reduce postoperative complications. This trial aims to investigate whether TXA-treated mastectomy pockets will exhibit less postoperative fluid production and complications. METHODS: This paired, double-blind, randomized, controlled trial enrolled patients undergoing bilateral mastectomies with immediate direct-to-implant reconstruction. In each patient, one breast was randomized to receive 3 g of TXA (100 cc), and the other received 100 cc of normal saline. The blinded solutions were soaked in the mastectomy pocket for 5 minutes before implant placement. Postoperatively, daily drain outputs, complications, and baseline demographics were recorded. RESULTS: Fifty-three eligible patients, representing 106 breasts, were enrolled. All patients underwent bilateral nipple-sparing mastectomies. After randomization, TXA was placed in the right breast in 30 patients (56.6%). The use of topical TXA resulted in a mean drain output reduction of 30.5% (range, -83.6% to 26.6%). Drains on the TXA-treated breast were eligible for removal 1.4 days (range, 0 to 4 days) sooner than the control side. The TXA-treated group had three complications (5.67%) versus 15 (28.3%) in the control group (OR, 0.1920; P = 0.0129). Specifically, for operative hematomas, the TXA group had none (0%), versus three in the control group (5.7%) (OR, 0.1348; P = 0.18). CONCLUSIONS: Soaking the mastectomy bed with 3% topical TXA before implant insertion leads to a decrease in drain output and a decrease in complications. Topical administration of TXA represents an option to decrease complications in alloplastic breast reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, I.
