Abstract

Background: The prognosis in acute spontaneous intracerebral hemorrhage (ICH) is related to hematoma volume, where >30 mL is commonly used to define large ICH as a threshold for neurosurgical decompression but without clear supporting evidence. Objective: To determine the factors associated with large ICH and neurosurgical intervention among participants of the Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trials (INTERACT). Methods: We performed pooled analysis of the pilot INTERACT1 (n = 404) and main INTERACT2 (n = 2839) studies of ICH patients (<6 h of onset) with elevated systolic blood pressure (SBP, 150-220mmHg)whowere randomized to intensive (target SBP<140mmHg) or contemporaneous guideline-recommended (target SBP < 180 mm Hg) management. Neurosurgical intervention data were collected at 7 d postrandomization. Multivariable logistic regression was used to determine associations. Results: There were 372 (13%) patients with large ICH volume (>30 mL), which was associated with nonresiding in China, nondiabetic status, severe neurological deficit (National Institutes of Health stroke scale [NIHSS] score ≥ 15), lobar location, intraventricular hemorrhage extension, raised leucocyte count, and hyponatremia. Significant predictors of those patients who underwent surgery (226 of 3233 patients overall; 83 of 372 patients with large ICH) were younger age, severe neurological deficit (lower Glasgow coma scale score, and NIHSS score≥15), baseline ICH volume>30 mL, and intraventricular hemorrhage. Conclusion: Early identification of severe ICH, based on age and clinical and imaging parameters, may facilitate neurosurgery and intensive monitoring of patients.
