Blunt splenic trauma: Can contrast enhanced sonography be used for the screening of delayed pseudoaneurysms?

摘要: Abstract Purpose To assess the value of contrast-enhanced sonography (CES) for detection delayed post-traumatic splenic pseudo-aneurysms, usually considered an indication angiographic embolization. Methods Sixty-three consecutive hemodynamically stable trauma patients in whom admission CT displayed a injury grade II or higher (AAST classification), without evidence vascular involvement, were included study. CES spleen using second generation contrast agent was systematically performed within 48–72 h after admission, pooling media suggestive pseudoaneurysm. Within 6 h sonography, all underwent abdominal control purposes. results compared to findings, which reference standard. This study received approval from institutional ethical board. Results showed blush consistent with pseudoaneurysm 6 63 patients. All confirmed at subsequent CT. Pooling found 2 negative. There no false positive examination suspicion pseudoaneurysms. When CT, sensitivity, specificity, and negative predictive values suggest pseudoaneurysms, 75% (6/8), 100% (55/55), (6/6), 96% (55/57), respectively. Conclusion Our data that may be useful screening traumatic pseudoaneurysms: if does not absolutely rule out pseudoaneurysm, warrants angiography, need
