According to recently reported classification, 46 patients with blunt splenic trauma were evaluated preoperatively with computed tomography(CT). Injuries were graded I through IV and described as capsular or subcapsular disruptions without parenchymal injury(3 patients); capsular and parenchymal injuries(23 patients); injuries involving hilum(3 patients); and fragmentation 917 patients). Nineteen patients were managed conservatively and 27 patients were managed surgically, Twelve patients(47%) out of those with Type Ior TypeIIwere managed surgically including five hemodynamically unstable patients and seven hemodynamically stable patients with associated injuries and unknown surgical criteria. On the other hand five hemodynamically stable patients(25%) out of those with Type IIIor Type IV were managed surgically. the amount of hemoperitoneum was graded into small, moderated and large; small in three patients, moderate in 39 patients, and large in two patients. the amount of emoperitoneum in patients with conservative treatment was moderate in 16 patients, moderate in 9 patients, and large in two patients. The amount of hemoperitoneum in patients with conservative treatment was moderate in 16 patients and large in one patient. And the amount of hemoperitoneum in patients with operative treatment was small in three patients, moderate in 23 patients and large in one patient. we concluded that CT was accurate method of determining the extent of splenic injury and evaluation of hemoperitoneum, but treatment choice should be based on the hemodynamic status of patients rather than the type of injury or the amount of hemoperitoneum by CT.
