Axillary lymph node dissection remains an integral part of surgical treatment of primarily node-positive invasive breast cancer. In order to reduce the incidence of clinically relevant seroma, a suction drain is routinely placed into the axillary cavity after axillary lymph node dissection (ALND) by a separate stab incision. The pathogenesis of seroma involves the collection of lymph fluid caused by dissection of lymph vessels and exudate. All coagulation and fibrinolytic factors are produced and secreted by lymphatic endothelial cells and are involved in the sealing of lymphatic capillaries. Local hemostyptic agents may therefore reduce postoperative secretion from lymphatic fistulas caused by ALND.
