Objective To investigate the clinical efficacy of internal decompression based on white matter tract preservation in the treatment of malignant middle cerebral artery infarction(MMCAI).Methods A retrospective analysis was conducted on 54 patients with MMCAI.Patients were divided into a study group(n=26)and a control group(n=28)according to the surgical approach.Patients in the study group underwent preoperative fusion of CT,CTP,DWI,and DTI imaging data within a neuronavigation system.This fusion visualized the spatial relationships between the infarct core(IC),ischemic penumbra,and the corticospinal tract(CST).Subsequently,IC resection combined with decompressive craniectomy(DC)was performed while protecting the CST.Patients in the control group underwent DC alone.Key outcome measures included:changes in fractional anisotropy(FA)within the affected CST projection area at 1 month postoperatively;and 6-month postoperative mRS score,mortality,and surgical complications at 6 months postoperatively.Results At 1 month postoperatively,FA in the affected CST projection area were significantly higher in the study group than in the control group(0.092±0.013 vs.0.082±0.008,P<0.05).At the 6-month follow-up,the postoperative mRS score in the study group was significantly lower than that in the control group[2.3(1.3,4.5)vs.3.9(2.4,5.5),P<0.05]and a lower mortality rate(11.5%vs.39.3%,P<0.05)compared to the control group.However,there were no statistically significant differences between the two groups in the incidence of postoperative intracranial hemorrhage,intracranial infection,or epilepsy(P>0.05).Conclusion Internal decompression based on white matter tract protection combined with DC can reduce mortality and contribute to improving function outcomes in patients with MMCAI.

Objective To investigate the effectiveness and safety of infarct core resection combined with decompressive craniectomy(DC)based on corticospinal tract(CST)protection in the treatment of massive cerebral infarction(MCI)with malignant brain edema.Methods This study retrospectively enrolled MCI patients with malignant brain edema who underwent internal decompression combined with DC at Xingtai Central Hospital from January 2021 to June 2024.The enrolled patients were divided into a control group and an experimental group base on the intracranial internal decompression method used.All patients underwent CT perfusion(CTP),CT angiography(CTA),diffusion-weighted imaging(DWI),and diffusion tensor imaging(DTI)within 24 h of admission.Preoperative imaging data was automatically processed using an artificial intelligence diagnostic system.For the experimental group,the imaging data was fused within a neuro-navigation system preoperatively to visualize the spatial relationships between the infarct core,ischemic penumbra,and CST and infarct core resection combined with DC was performed while protecting the CST through neuro-navigation.The control group underwent anterior temporal lobectomy combined with DC.Baseline and clinical data were collected from both groups,including gender,age,smoking history,alcohol consumption history,diabetes,hypertension,hyperlipidemia,hyperhomocysteinemia,atrial fibrillation history,responsible occluded vessel(internal carotid artery,middle cerebral artery),preoperative infarct volume on DWI,preoperative ischemic penumbra volume,preoperative the National Institutes of Health stroke scale(NIHSS)score,time from onset to surgery,intraoperative procedure duration,intraoperative blood loss,preoperative and 1-month postoperative fraction anisotropy(FA)values of the CST on the affected side,modified Rankin scale(mRS)score at 6 months postoperatively,and surgery-related complications within 1 month postoperatively(intracranial hemorrhage[operative site oozing,hemorrhagic transformation]and intracranial infection[surgical incision site infection,empyema,brain abscess,meningitis]).6-month follow-up after surgery were conducted through outpatient visit or telephone calls and prognosis of patients was evaluated using the mRS(with mRS of 0-3 defined as good prognosis,4-6 as poor prognosis,and 6 indicating death).The effectiveness indicators included FA value of the affected CST at 1 month postoperatively,good prognosis rate after surgery at 6 months,and 6-month mortality rate after surgery.The safety indicators included the incidence rates of surgical complications(intracranial hemorrhage and infection)within 1 month postoperatively.Based on preoperative DTI images,all patients were further divided into a CST-intact(infarct core did not invade CST,CST morphology intact or deformed/shifted)and a CST-damaged(infarct core invaded CST,CST disrupted or interrupted)subgroup for analysis.Results A total of 62patients(37 males,25 females,age 49-60 years,mean[55±4]years)were enrolled in this study.With 28 patients in the experimental group and 34 in the control group.(1)No significant differences were found in baseline or clinical data between the experimental and control groups(all P>0.05),and the reoperative FA values of the affected CST were showed no significant differences(P=0.588).(2)The efficacy and safety metrics were evaluated.For the efficacy indices,at 1 month after the surgery,FA values of the affected CST increased significantly compared to preoperative values in both groups(0.409±0.051 vs.0.312±0.052 in the experimental group,and,0.381±0.048 vs.0.319±0.049 in control group;both P<0.05),and the FA value was significantly higher in the experimental group than that in the control group(0.409±0.051 vs.0.381±0.048,P=0.030).At the 6-month follow-ups,the good prognosis rate was significantly higher in the experimental group than that in the control group(39.3%[11/28]vs.14.7%[5/34],P=0.028).No significant difference in the 6-month mortality rate were observed between the two groups(P=0.787).For the safety indices,no significant differences were found in the incidence rates of intracranial hemorrhage or intracranial infection within 1 month postoperatively between the two groups(both P>0.05).(3)For further subgroup analysis,no significant differences were found in baseline or clinical data between the CST-damaged subgroup and the CST-intact subgroup in both the experimental and control groups(all P>0.05).In CST-intact subgroup,FA values of the affected CST increased significantly at 1 month postoperatively compared to preoperatively in the study group(0.428±0.047 vs.0.342±0.045,P<0.05)and the control group(0.401±0.051 vs.0.347±0.048,P<0.05).While in the CST-damaged subgroup,no significant differences were found in FA value of the affected CST 1 month postoperatively compared with that preoperatively in both the experimental and control groups(bothP>0.05).A significantly higher FA values 1 month postoperatively(0.428±0.047 vs.0.401±0.051,P=0.036)and good prognosis rate(9/12 vs.4/16,P=0.020)were observed in the CST-intact subgroup of the experimental group comparing with that of the control group,while there was no statistically significant difference in the 6-month mortality rate between the groups within the CST-intact subgroup(P=1.000).There were no statistically significant differences between the experimental group and the control group in both efficacy and safety indices within the CST-damaged subgroup(all P>0.05).Conclusions Infarct core resection combining DC with CST protection demonstrates superior neurological functional improvement in comparison with anterior temporal lobectomy combining DC in treating MCI with malignant brain edema,particularly for patients with an intact CST before surgery(as indicated in patients'preoperative imaging results).This(infarct core resection combining DC with CST protection)approach does not increase the incidence of surgical complications.Prospective large sample controlled studies are required for further validation.

Objective To explore the correlation between glycolysis related indexes of peripheral blood mononuclear cells(PBMCs)[glucose transporter 1(GLUT1),fructose-2,6-diphosphatase 3(PFKFB3)and lactate kinase M2(PKM2)]and intracranial pressure and clinical prognosis of patients with hypertensive cerebral hemorrhage(HICH)who broke into the ventricle.Methods 85 HICH patients hospitalized in our hospital from January 2021 to June 2022 were retrospectively collected as the research participants.The levels of PKM2,GLUT1 and PFKFB3 in PBMCs were analyzed by enzyme-linked immunosorbent assay kit.Six months after the onset of HICH,the short-term outcome was evaluated by modified Rankin scale(mRS),and the patients were divided into good prognosis(mRS score≤2)and poor prognosis(mRS score≥3).Results The levels of PKM2,PFKFB3 and GLUT1 in PBMCs of HICH patients with ventricular rupture were further lower than those of the patients without ventricular rupture(P<0.05).Six months after discharge,8 patients(22.9%)with HICH in non-ventricular rupture group had poor prognosis,while 28 patients(56.0%)with HICH in ventricular rupture group had poor prognosis,and the difference was statistically significant(χ2=9.263,P=0.002).Compared with the group with good prognosis,the levels of PKM2 and GLUT1 in PBMCs of HICH patients with poor prognosis were lower(P<0.05).Compared with the good prognosis group,the levels of PKM2 and GLUT1 in PBMCs of HICH patients with poor prognosis group were lower in HICH patients with ventricular rupture(P<0.05).In HICH patients who broke into the ventricle,the AUC of PKM2 and GLUT1 in predicting the poor prognosis of HICH patients were 0.879(95%CI:0.807~0.951)and 0.897(95%CI:0.831~0.963),respectively.Conclusion The levels of PKM2 and GLUT1 in PBMCs of patients with HICH breaking into ventricles decrease significantly,and are negatively correlated with intracranial pressure,which can be used to predict the short-term prognosis of the patients.
