The severity of head injury, performing a duraplasty rather than a slit durotomy, avoidance of a contralateral DC, and the presence of preoperative hypotension, infarct, and/or pupillary asymmetry have the highest odds of predicting the short term GOS at the time of discharge, after a DC in patients with TBI. Although DC carries a high risk of mortality, the probability of the survivors having a favorable outcome is significantly more as compared to those who remain in a PVS.
