title: Spontaneous hematoma of the lateral abdominal wall caused by a rupture of a deep circumflex iliac artery: report of two cases.
abstract: Expanding hematoma of the abdominal wall is a rare example of acute abdominal disease. We report two cases of lateral abdominal wall hematoma caused by the rupture of a deep circumflex iliac artery, which is a rare cause of an abdominal wall hematoma. Both patients experienced severe abdominal pain after sneezing or coughing. In both cases, computed tomography (CT) findings suggested that active bleeding was continuing. Emergent angiography was therefore performed, and the hematoma was embolized using Spongel or Microcoils. Ultrasound examinations were repeatedly used to monitor the size of the hematoma. The size of the hematoma and patient's pain gradually decreased after embolization. Ultrasound and CT examinations provided useful information for the differential diagnosis of this disease. We conclude that emergent angiography should be performed to control bleeding and avoid any unnecessary surgical procedures in patients with hematoma of the abdominal wall.
