Massive hemoperitoneum due to ruptured inferior phrenic artery pseudoaneurysm after blunt trauma.

There had been no previous reports of ruptured pseudoaneurysm of inferior phrenic artery shortly after blunt abdominal trauma. Traumatic arterial pseudoaneurysms are either iatrogenic or the result of penetrating injuries and one of the sequelae of trauma. Post-traumatic pseudoaneurysm develops at varying time intervals after the initial insult. To our knowledge, this is the first report of massive hemoperitoneum caused by ruptured inferior phrenic artery pseudoaneurysm after blunt trauma. Pseudoaneurysm of inferior phrenic artery in patient with diaphragm injury is potentially a life-threatening condition and requires urgent management. Diagnosis of ruptured inferior phrenic artery pseudoaneurysm is based on clinical assessment combined with radiological investigations. We report a case of ruptured left inferior phrenic artery pseudoaneurysm as one aspect of massive hemoperitoneum caused by blunt abdominal trauma.
