Objective: Thrombolysis in Cerebral Infarction(TICI) score is used to objectively evaluate cerebral perfusion after intervention in acute stroke with mechanical thrombectomy. In our study, we aimed to compare the results of patients with successful TICI perfusion score (TICI ≥ 2c) with the results of patients with poor TICI perfusion score (TICI < 2c) and to investigate the relationship of the CHADS-VASc scoring system with the final TICI perfusion score and other endpoints.

Methods: For this retrospective, single-center, cross-sectional study, 278 patients who underwent endovascular thrombectomy were screened consecutively by the interventional neurology department of hospital. The primary endpoint of the study was in-hospital and 1-year all-cause death. All patients underwent cranial imaging to evaluate hemorrhagic transformation after the procedure.

Results: It was observed that CHADS-VASc score was significantly higher in the poor cerebral perfusion group than in the succesful cerebral perfusion group (3.19 ± 1.8 vs 2.72 ± 1.73, p = 0.046). According to Kaplan Meier's analysis, a significant difference was observed in the group with a CHADS-VASc score > 2.5 in terms of all-cause mortality at follow-up compared to the group with a low CHADS-VASc score (p = 0.002). According to Kaplan Meier's analysis, a significant difference was observed in the group with a poor TICI score compared to the group with a succesful one in terms of all-cause mortality at follow-up (p < 0.001). Cox regression model showed that poor TICI score group, Age ≥ 75 years, lower glomerular filtariton rate (GFR), higher high-sensitiveC-reactiveprotein (Hs-CRP), and higher admission NIHSS score were independent predictors of 1-year all-cause mortality.

Conclusion: High CHADS-VASc score has been shown to be a predictor of unsuccessful cerebral perfusion score and 1-year mortality after mechanical thrombectomy in stroke patients. As a result of our research, it has been shown that complete or nearly complete reperfusion has more positive results than partial reperfusion.

Objectives: Mechanical thrombectomy (MT) has revolutionized the treatment of acute ischemic stroke (AIS). Still, the efficacy and safety in patients older than 85 years of age are not conclusive by the present randomized controlled trials' data (RCT). Aging is a multifactorial process and the impact of MT on this specific population needs to be further analyzed.

The alteration of neurovascular coupling (NVC), where acute localized blood flow increases following neural activity, plays a key role in several neurovascular processes including aging and neurodegeneration. While not equivalent to NVC, the coupling between simultaneously measured cerebral blood flow (CBF) with arterial spin labeling (ASL) and blood oxygenation dependent (BOLD) signals, can also be affected. Moreover, the acquisition of BOLD data allows the assessment of resting state (RS) fMRI metrics.

Introduction: Hemorrhage is the leading cause of preventable deaths in trauma patients, resulting in 1.5 million deaths annually worldwide. Traditional trauma assessment follows the ABC (airway, breathing, circulation) sequence; evidence suggests the CAB (circulation, airway, breathing) approach to maintain perfusion and prevent hypotension.

The compliant nature of cerebral blood vessels may represent an important mechanical protection for sustained cerebral perfusion during reductions in arterial blood pressure (ABP). However, whether the rise in cerebrovascular compliance (Ci) with falling ABP persists and exhibits a threshold effect remains unknown. Therefore, we analyzed Ci changes during graded head-up tilt (HUT) in individuals with autonomic failure (AF), a group that tolerates graded and progressive reductions in ABP.

Besides intravenous thrombolysis, endovascular therapy (EVT) is also a standard treatment option for acute ischemic stroke. The clinical efficacy and safety of this procedure was proven in 2015 by several randomized controlled trials. The aim of EVT is to achieve the fastest possible recanalization of an occluded artery supplying the brain and, thus, reperfusion of the brain tissue.
