Abstract:Objective To investigate the characteristics of occasional postoperative further infarction (PFI) and its influencing factors in insular-involving gliomas (IIG).Methods A total of 150 IIG patients were followed up. The characteristics and influencing factors of 7 PFI patients were investigated, and related literature was reviewed.Results The mean age of PFI patients was 42.86±7.58 years, and 6 patients were males. Six patients were accompanied by hypertension and diabetes, and 6 patients had a long history of smoking. The locations of the tumors were homogeneously distributed, all the tumors were totally resected, and the pathological results all revealed astrocytoma components. The mean time to PFI was 11.6±7.1 months. Tumor was closely correlated with the middle cerebral artery in 6 patients, transsylvian approach was used in 5 patients, and neurological disorder was aggravated in 5 patients. Spot- and sheet-shaped nuclear magnetic resonance signals were seen in the basal ganglia region in 5 patients.Conclusions IIG patients who are elderly males, have vascular risk factors, show a close correlation between tumor and artery, have astrocytoma components in pathological results, achieve total resection via the transsylvian approach, and suffer from aggravation of neurological disorder after surgery should be cautious of PFI.
