A retrospective review of patients who developed hematoma following breast surgery from 2003 to 2018 in a single institution was performed. The study investigated the value of closed-suction drains regarding the quantity and quality of fluid secretion for the prediction of subcutaneous hematoma in patients undergoing breast surgery procedures.

Inclusion Criteria:

• Patients who developed hematoma requiring revision following bilateral breast surgery including augmentation mammoplasty, subcutaneous mastectomy and breast reduction.

Exclusion Criteria:

• Patients who developed hematoma requiring revision following unilateral breast surgery.
• Breast surgery in absence of hematoma.
• Patients with known coagulation disorders.

We enrolled 20 subjects who developed unilateral hematoma requiring evacuation following bilateral breast surgery between January 2008 and January 2018 at our institution. Gender, age, breast surgery subtype, preoperative and postoperative hemoglobin values as well as perioperative heparinization were recorded.
