Abstract：Objective To investigate the effect of abnormal iron metabolism on neurological func-tion in elderly patients with hypertensive intracerebral hemorrhage(HICH)after minimally inva-sive surgical evacuation.Methods A prospective study was conducted on 300 elderly patients with HICH admitted to our hospital from January 2021 to December 2023.At 28 d after surgery,Glas-gow Outcome Scale(GOS)was used to assess the presence of neurological deficits or not,and then they were divided into a good neurological function group(GOS score≥4,175 cases)and a poor neurological function group(GOS score＜4,125 cases).Iron deposition in cerebrospinal fluid and serum iron metabolism were compared between the two groups,and the risk factors for neu-rological deterioration were analyzed.Results Compared with the good neurological function group,the poor neurological function group exhibited significantly decreases in Glasgow coma scale(GCS)scores at admission and 7 d after admission and iron ions(P＜0.01).Bleeding vo-lume,ferritin,transferrin,and quantitative susceptibility mapping(QSM)values of the thalamus and the hippocampus were obviously increased upon admission(P＜0.01).Multi variate logistic regression analysis showed that admission bleeding volume(OR=1.083,95％CI:1.012-1.159,P=0.021),ferritin(OR=1.065,95％CI:1.016-1.116,P=0.009),and thalamic QSM value(OR=4.075,95％CI:2.848-5.830,P=0.000)were risk factors for neurological dysfunction in the HICH patients after minimally invasive surgical treatment,while GCS score(OR=0.430,95％CI:0.259-0.715,P=0.001)and iron ions(OR=0.193,95％CI:0.064-0.581,P=0.003)at 7 d of admission were protective factors.Conclusion Iron deposition in cerebrospinal fluid and abnormal iron metabolism in serum are related to the deterioration of neurological function in eld-erly patients with HICH after minimally invasive hematoma evacuation,and are regarded as po-tential therapeutic targets.
