PURPOSE: This study was performed to evaluate the value of repeated CT scans for the non-operative management of patients with clinically stable blunt splenic trauma. METHODS: 49 consecutive patients with blunt splenic trauma were prospectively studied. Of these, 29 (59.2%) were initially managed non-operatively according to their clinical status and initial CT findings. A repeat CT scan was obtained within 7 days of admission. RESULTS: Of the 29 non-operatively managed patients, 5 (17.2%) required delayed surgical intervention: 3 presented with a change in thier clinical status, whereas the other 2 did not. In all 5 patients, a repeat CT scan revealed a deteriorating appearance of the splenic injury: active bleeding or an increased hematoma in 3, with splenic artery pseudoaneurysms in the other 2. CONCLUSION: This initial experience suggests that a repeat CT scan can provide valuable clinical information in selected cases on the diagnosis and management of a splenic injury to document the healing or progression of the injury.
