MASSIVE SUBCUTANEOUS HEMORRHAGE DUE TO MINOR BLUNT TRAUMA : RETROSPECTIVE REVIEW

Abstract

　　Acute massive subcutaneous hemorrhage may cause hemodynamic instability or be life-threatening. Massive subcutaneous hemorrhage is defined as subcutaneous hemorrhage of the trunk that can not be stopped spontaneously and requires hemostasis. We retrospectively examined patients (n = 8) with massive subcutaneous hemorrhage following minor blunt trauma who were treated using superselective transcatheter arterial embolization at our hospital between April 2019 and April 2020. Despite compression hemostasis, six patients were in shock and six required blood transfusions, suggesting that a history of hemodialysis, anticoagulation, and antiplatelet medication may be a high-risk factor. In the trunk, hematomas grow concentrically, which can cause massive bleeding without sufficient compression at the bleeding point. In contrast medium extravasation patients, aggressive hemostasis is effective.
