Authors: Zhang HT, Chen LH, Xu RX Abstract BACKGROUND This case series study evaluated the outcome and effect of portable 3D-head computed tomography (CT, MCT-I, 16 rows mobile CT made in China) navigation-guided key-hole microsurgery for supratentorial hypertensive hematomas. MATERIAL AND METHODS Thirty-five consecutive unconscious patients with a significant volume of hypertensive intracranial hemorrhages (HICH) were treated with 3D image-guided key-hole microsurgery, and the clinical features were summarized. Preoperative and postoperative hematoma volumes and reduction in midline shifts were calculated and reco...

Authors: Gitsioudis G, Nunninger M, Missiou A, Wolf P, Katus HA, Korosoglou G Abstract Background: Non-invasive computer tomography (CT)- and magnetic resonance (MR)-based cardiac imaging still remains challenging in rodents. To investigate the robustness of non-invasive multimodality cardiac imaging in rabbits using clinical-grade CT and MR scanners. Methods: A total of 16 rabbits (2.7-4.0 kg) serially underwent cardiac-gated imaging using a clinical-grade 256-row CT and a 1.5 Tesla MR-scanner at baseline and at 4-month follow-up (16±1 weeks). Image analysis included image quality (5-grade scale), left ...

ConclusionAdding CTP and/or a delayed-phase CTA to NCCT with arterial-phase CTA improves the decision-maker ’s confidence level and creates a trend towards a lower threshold for mechanical thrombectomy.

CONCLUSIONS: Higher resistin and chemerin blood concentrations significantly increase the risk of ischemic stroke. The level of stroke severity in the moment of its occurrence and its course do not depend on the concentrations of adipocytokines under analysis. PMID: 31851370 [PubMed - as supplied by publisher]

Background: Controversial evidence suggests that right insular stroke may be associated with worse outcomes compared to the left insular ischemic lesion. Objectives: We investigated whether lateralization of insular stroke is associated with early and late outcome in terms of in-hospital complications, stroke recurrence, cardiovascular events, and death. Methods: Data were prospectively collected from the Athens Stroke Registry. Insular cortex involvement was identified based on brain CT scans or MRI images.

AbstractIntroductionSymptomatic intracerebral hemorrhage (sICH) following systemic thrombolysis for ischemic stroke is often devastating, and open surgical evacuation is considered dangerous due to the increased risk of perioperative bleeding, and stereotactic placement of a catheter is too time-consuming. We therefore evaluated the feasibility of a free-hand bedside catheter technique for emergency hematoma evacuation.MethodsPatients who had a supratentorial sICH after thrombolysis, a hematoma volume  >  30 ml, and an ensuing reduction in vigilance were consecutively treated with acute minimally inva...

ASPECTS (Alberta Stroke Program Early CT Score) is a 10-point topographic CT scan score that has been shown to be a strong prognostic factor in acute ischemic stroke. We investigated whether all ASPECTS regions have the same prognostic value.

Conclusions: DDAVP was associated with a decreased likelihood of intracranial hemorrhage expansion during the first 24 hours. DDAVP administration did not significantly affect serum sodium and thrombotic events during the study period.

Study Design. Retrospective cohort study. Objective. Compare a novel two-step algorithm for indicating a computed tomography angiography (CTA) in the setting of a cervical spine fracture with established gold standard criteria. Summary of Background Data. As CTA permits the rapid detection of blunt cerebrovascular injuries (BCVI), screening criteria for its use have broadened. However, more recent work warns of the potential for the overdiagnosis of BCVI, which must be considered with the adoption of broad criteria. Methods. A novel two-step metric for indicating CTA screening was compared with the American Coll...
