Risk factors and preventive strategies for postoperative cerebral infarction in patients with hypertensive intracerebral hemorrhage.

To identify the risk factors and evaluate preventive strategies for postoperative cerebral infarction (CI) in patients withhypertensive intracerebral hemorrhage (HICH). This retrospective study included 268 patients who underwent surgery for HICH at Yiwu Central Hospital between November 2022 and November 2024. Among them, 50 developed postoperative CI (CI group), while 218 patients did not (non-CI group). Logistic regression analysis was used to identify independent risk factors for postoperative CI, and receiver operating characteristic (ROC) curves were generated to assess the predictive performance of the identified variables. Among the 268 HICH patients, 50 patients developed postoperative CI, resulting in an incidence of 18.66%. Compared to the non-CI group, patients in the CI group had notably lower Glasgow Coma Scale (GCS) scores, and larger hematomas and higher brain edema volumes (all P<0.001). Logistic regression analysis identified systolic blood pressure (P<0.001; OR: 1.169; CI: 1.099-1.244), diastolic blood pressure (P=0.027; OR: 1.094; CI: 1.010-1.185), GCS score (P=0.017; OR: 0.753; CI: 0.596-0.951), and hematoma volume (P=0.004; OR: 1.229; CI: 1.067-1.414) as independent risk factors for postoperative CI in HICH patients. The combined predictive model yielded an area under the ROC curve (AUC) of 0.867. Elevated systolic and diastolic blood pressure, lower GCS scores, and larger hematoma volume are independent risk factors for postoperative CI in HICH patients.
