ObjectivesDetermining the value of the computed tomographic black hole sign in predicting postoperative rehemorrhage in patients with intracranial hemorrhage (ICH) underwent minimally invasive surgery (MIS).MethodsTwo hundred ninety-five patients with spontaneous ICH underwent stereotactic MIS within 24 hours after admission. Ninety-eight patients (33%) demonstrated a black hole sign on initial computed tomography (CT). Postoperative rehemorrhage occurred in 68 patients (named the rehemorrhage group, including patients with and without black hole sign) and the other 227 patients (non-rehemorrhage group) did not show rehemorrhage. Multivariable logistic regression analyses were performed to assess the values of the black hole sign.ResultsPostoperative rehemorrhage occurred in 57 of the 98 (58.2%) patients with the black hole sign, and in 11 of the 197 (5.58%) patients without the black hole sign. In the rehemorrhage group, 39 patients (57.4%) were found to have the black hole sign. However, only 59 patients (25.99%) from the non-rehemorrhage group showed the black hole sign. The sensitivity, specificity, and positive and negative predictive values of the black hole sign for predicting postoperative rehemorrhage were 57.4%, 74%, 39.8%, and 85.3%, respectively. The odd ratio for the black hole sign, the hematoma irregularity, and the CT value for predicting the postoperative rehemorrhage were 10.501, 9.631, and 4.750, respectively.ConclusionsThe black hole sign on initial CT could predict the postoperative rehemorrhage following the minimally invasive procedures.Copyright © 2018.
