Background: Perioperative blood transfusion is associated with an increased risk of adverse events and tranexamic acid (TXA) use has been proposed to decrease the need for perioperative blood transfusion. Herein, we seek to investigate the impact of intraoperative TXA on perioperative risk of VTE in a subset of patients who underwent robotic-assisted radical cystectomy (RARC) for bladder cancer. Methods: We queried the prospectively maintained Mayo Clinic Radical Cystectomy registry and identified patients who underwent RARC between 2004-2021 and received TXA intraoperatively. In univariable and multivariable analyses, we investigated factors associated with bleeding and VTE within 30 days post-operatively. Results: Of 2862 patients, we identified 94 patients who received TXA (IV) intraoperatively (Group A) and were propensity score matched 1:1 for age, neoadjuvant chemotherapy, pT stage, pN stage, and preoperative hemoglobin with a group who did not receive TXA; 38 patients (Group B). In univariable and multivariable models, use of TXA has no statistically significant impact on patient’s risk of bleeding or VTE. In a univariable model, number of positive lymph nodes and extent of lymph node dissection were associated with increased risk of VTE (Table 1). Conclusions: In our study, use of TXA in patient’s undergoing RARC was safe and was not associated with increased risk of VTE.
