Abstract Background The surgical management of deep brain lesions is challenging, with significant morbidity. Advances in surgical technology have presented the opportunity to tackle these lesions. Methods We performed a complete resection of a thalamic/internal capsule CM using a tubular retractor system via a parietal trans-sulcal para-fascicular (PTPF) approach without collateral injury to the nearby white matter tracts. Conclusion PTPF approach to lateral thalamic/internal capsule lesions can be safely performed without injury to eloquent white matter fibres. The paucity of major vessels along this trajectory and the preservation of lateral ventricle integrity make this approach a feasible alternative to traditional approaches.

The Relationship

Introduction: Cerebral small vessel diseases (SVDs) i.e. white matter lesion and cerebral microbleeds (CMBs) are related to the patients with stroke more deeply than those without. In general population, in addition to age, hypertension, diabetes chronic kidney diseases (CKD) is well known to be related to SVDs, but it remains unclear in patients with stroke. We investigated the relationship between CKD and the presence of SVDs in patients with acute ischemic stroke. Methods: We enrolled 493 patients with acute ischemic stroke patients or transient ischemic attack patients (mean age 71; 60% male) who had undergone 1.5T MR imaging within a week of the index events from April 2013 to march 2015. We evaluated kidney function by estimated glomerular filtration rate (eGFR) with the modification of diet in Renal Disease. CKD was defined as an eGFR less than 60mil/min/1.73m 2 . CMBs were defined as focal areas of very low signal intensity smaller than 10mm. White matter lesion as Periventricular hyper intensity (PVH)>grade 2 and Deep and Subcortical White Matter Hyper intensity (DSWMH)> grade 2 were defied as advanced PVH and advanced DSWMH, respectively. We investigated relationship between CKD and CMBs, advanced PVH and advanced DSWMH using a logistic regression analysis. Results: We noted CMBs in 173 patients (35%), PVH in 81 (16%), and DSWMH in 151 (31%). An univariate analysis revealed that the age, CKD, history of stroke, and antiplatelet agents were associated with presence of CMBs, advanced PVH and severe DSWMH . The multivariate analysis revealed that CMBs, advanced PVH and advanced DSWMH were associated with age (CMBs: odds ratio(OR) ; 1.32 ; 95% confidence interval(CI), 1.10-1.60, p=0.004, advanced PVH : OR ; 3.00 ; 95% CI, 2.17-4.26, p<0.01, advanced DSWMH: OR ; 1.94; 95% CI, 1.56-2.45, p<0.01 ), history of stroke(CMBs : OR ; 2.01 ; 95% CI, 1.21-3.34, p=0.007, advanced PVH : OR ; 2.25 ; 95% CI, 1.18-4.27, p=0.01, advanced DSWMH: OR ; 1.78 ; 95% CI, 1.03-3.06, p=0.038). CKD was associated with CMBs (OR ; 1.62 ; 95% CI, 1.04-2.52, p=0.03), but PVH and DSWMH were not. Conclusions: It seems that age and history of stroke are related to CMBs, advanced PVH and advanced DSWMH, and that CKD is associates with CMBs but not with either advanced PVH or advanced DSWMH.

The Relationship

Blood-based bioenergetic profiling has promising applications as a minimally invasive biomarker of systemic bioenergetic capacity. In the present study, we examined peripheral blood mononuclear cell (PBMC) mitochondrial function and brain morphology in a cohort of African Americans with long-standing Type 2 diabetes. Key parameters of PBMC respiration were correlated with white matter, gray matter, and total intracranial volumes. Our analyses indicate that these relationships are primarily driven by the relationship of systemic bioenergetic capacity with total intracranial volume, suggesting that systemic differences in mitochondrial function may play a role in overall brain morphology.

ObjectivesRecent studies reported that 24-hour ambulatory blood pressure variability (ABPV) was associated with lacunar infarction and white matter hyperintensities (WMH). However, the relationship between ABPV and enlarged perivascular spaces (EPVS) has not been investigated. Thus, our study aimed to investigate whether ABPV is associated with EPVS by 24-hour ambulatory blood pressure monitoring (ABPM).DesignWe conducted this study as a cross-sectional study.SettingsThe study was based on patients who presented for physical examinations in our hospital from May 2013 to June 2016.ParticipantsPatients with both brain MRI scans and 24-hour ABPM were included and patients with acute stroke, a history of severe stroke and some other severe diseases were excluded. A total of 573 Chinese patients were prospectively enrolled in this study.Primary and secondary outcome measuresEPVS in basal ganglia (BG) and white matter (WM) were identified on MRI and classified into three categories by the severity. WMH were scored by the Fazekas scale. Coefficient of variation (CV) and SD were considered as metrics of ABPV. Spearman correlation analysis and ordinal logistic regression analysis were used to assess the relationship between ABPV and EPVS.ResultsThere were statistical differences among the subgroups stratified by the severity of EPVS in BG in the following ABPV metrics: SD and CV of systolic blood pressure (SBP), CV of diastolic blood pressure (DBP) in 24 hours, daytime and nighttime and SD of DBP in nighttime. The above ABPV metrics were positively associated with the degree of EPVS. The association was unchanged after adjusting for confounders. Spearman correlation analysis showed ABPV was not related to the degree of EPVS in the WM.ConclusionABPV was independently associated with EPVS in BG after controlling for blood pressure, but not in the WM. Pathogenesis of EPVS in BG and WM might be different.
