Abstract
Background
Seroma is the most common complication after mastectomy and reconstruction surgery. Therefore, this study aimed to determine whether the topical application of tranexamic acid would be useful to reduce seromas in a rat mastectomy model.
Methods
Forty-eight Sprague–Dawley rats were divided into four groups. After mastectomy and axillary lymph node dissection, 0.4 mL of normal saline was administered to group A in the dead space. In group B, 0.4 mL of a triamcinolone mixed solution was administered. In group C, 0.4 mL of a tranexamic acid (10 mg/kg) mixed solution was administered. In group D, 0.4 mL of a tranexamic acid (50 mg/kg) mixed solution was administered. Gross examination, assessment with micro-computed tomography (CT), quantitative analysis via aspiration, and histopathologic assessment were implemented 7 and 14 days postoperatively.
Results
No other complications such as wound infection and skin necrosis were observed. At postoperative week 1, groups B and C showed significantly lower seroma volume values on micro-CT (P < 0.001 and P < 0.05, respectively) and seroma volume values at aspiration (P < 0.01 and P < 0.001, respectively) than group A. According to histopathologic analysis, inflammation was observed more frequently in groups A and D than in the other groups, and angiogenesis was more active in groups B and C than in the other groups.
Conclusions
Topical application of tranexamic acid was as effective as topical application of triamcinolone to prevent seroma formation. The stability of tranexamic acid was confirmed when the high dose of tranexamic acid was used.
