Abstract
The aim of this study was to assess a newly developed computerized tomography (CT)-based splenic injury index in predicting the outcome of splenic injury. Twelve patients with isolated splenic injuries were studied. Splenic parenchymal injury was graded from 1 to 4 based on CT. The splenic injury index was obtained by multiplying the parenchymal score by the volume of haemoperitoneum, which was measured on the CT scanner. The 12 patients with CT-proven splenic injuries had a mean injury index of 193.5 ± 191 (mean ± s.d.). The 3 patients who failed conservative management had a mean index of 475 ± 50, compared with an index of 99.5 ± 100 in the nine managed non-operatively (P < 0.001). This new CT-based splenic injury index allows morphological assessment of splenic injury and may predict the outcome of splenic trauma.
