Prediction of functional outcome in supratentorial intracerebral hemorrhage patients treated with stereotactic computed tomographic-guided aspiration and recombinant tissue plasminogen activator (rt-PA)

Background and purpose: Minimally invasive surgery for ICH has shown a significantly improved functional outcome for selected ICH patients. This study aimed to evaluate the factors influencing the outcome of supratentorial ICH patients treated with stereotactic computed tomographic (CT) guided recombinant tissue plasminogen activator (rt-PA). Methods: We retrospectively evaluated data from 80 consecutive supratentorial ICH patients between December 2017 and July 2020, analyzing their 180-day outcomes, and identifying clinical, radiological factors for good prognosis within 180 days. Results: The mean age was 55.6 years (SD 11.4). The median preoperative Glasgow Coma Scale (GCS) score was 9 (interquartile range - IQR 6-12). The mean final ICH volume was 26.5 ml (SD 27.5), with ICH volume reduction by an average of 66.7 %. Six months after the procedure, 40 patients (50 %) had favorable outcomes (modified Rankin Scale [mRS]) score 0-3). In multivariate analysis, age (odds ratio [OR] = 0.939, 95 % confidence interval (CI) = 0.894 - 0.986; p = 0.012), the GCS score before operation (OR = 1.525, 95 % CI = 1.008 - 2.309; p = 0.046), the initial midline shift (OR = 0.808, 95 % CI = 0.661 - 0.988; p = 0.038), and the residual volume hematoma (OR = 0.949, 95 % CI = 0.908 - 0.992, p = 0.020) were the significant predictors of a favorable 180day outcome. Receiver operating characteristic curve analysis confirmed that the best cut-off point for predicting the good functional 180-day outcome was a GCS score of 9 before the procedure [area under the curve: 0.721, 95 % CI = 0.608 - 0.833, p = 0.001]. Conclusion: CT-guided thrombolysis and aspiration can be safe and effective in reducing ICH volume. A preoperation GCS score above or equal to 9 and younger age were associated with improved long-term outcomes in patients with supratentorial ICH.
