Splenic artery embolization for post-traumatic splenic artery pseudoaneurysm in children.
Although rare, traumatic splenic artery pseudoaneurysm (SAP) can be life threatening. The diagnostic approaches as well as the methods of treatment of SAP are yet to be determined. We present the case of a 10-year-old boy treated conservatively for a grade III blunt splenic injury (BSI). The child was discharged to home after a 5-day uneventful hospitalization but was found on routine follow-up CT scan to have a large SAP. The pseudoaneurysm was successfully angiographically embolized and subsequent abdominal CT demonstrated successful resolution of the pseudoaneurysm with a small residual splenic cyst. We reviewed the eight cases of post-traumatic SAP in children that have been published in the English literature. Unlike SAP in adult patients, the severity of the splenic injury does not have predictive value for development of SAP in children. Abdominal pain was the most frequent symptom of SAP, but three children were asymptomatic at the time of diagnosis. Therefore, the possibility of SAP should be investigated even in the asymptomatic child with mild splenic injury. When a splenic pseudoaneurysm is diagnosed, we believe splenic artery embolization is indicated.
