Asymptomatic Carotid Stenosis Is Associated With Circadian and Other Variability in Embolus Detection
Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this t...

Aortic Arch Reconstructive Surgery with Conventional Techniques versus Frozen Elephant Trunk: A Systematic Review and Meta-Analysis
Conclusion Current evidence suggests that FET surgery is associated with lower mortality in patients with thoracic aneurysmal disease and dissections, without a significant increase in stroke, bleeding or operative times. However, the risk of spinal cord ischemia is increased in FET patients. A well powered randomized trial is needed to evaluate this evolving field. Teaser To our knowledge, we have performed the most detailed meta-analysis for the use of Frozen Elephant Trunk (FET) surgery, yielding a systematic review with the most number of patients studied. Our systematic review and meta-analysis uses the most up to dat...

Homocysteine and homocysteine-related compounds: an overview of the roles in the pathology of the cardiovascular and nervous systems.
HOMOCYSTEINE AND HOMOCYSTEINE-RELATED COMPOUNDS: AN OVERVIEW OF THE ROLES IN THE PATHOLOGY OF THE CARDIOVASCULAR AND NERVOUS SYSTEMS. Can J Physiol Pharmacol. 2018 Aug 21;: Authors: Djuric D, Jakovljevic V, Zivkovic VI, Srejovic IM Abstract Homocysteine, sulfhydryl group containing amino acid, is intermediate product during metabolism of the amino acids methionine and cysteine. Hyperhomocysteinema (HHcy) is used as a predictive risk factor for cardiovascular disorders, the stroke progression, screening for inborn errors of Met metabolism, and as a supplementary test for vitamin B12 deficiency. Two org...

Early Clinical Outcomes of Hybrid Arch Frozen Elephant Trunk Repair with the Thoraflex Hybrid Graft
ConclusionsHybrid aortic arch and FET repair with the Thoraflex hybrid graft appears to be associated with good clinical outcomes, despite being early in the learning curve with this graft. Further investigation with this device is warranted to establish its role within the variations of hybrid arch repair.

Characteristic Cerebrovascular Findings Associated with ACTA2 Gene Mutations.
Abstract A specific mutation (Arg179) of the ACTA2 gene has previously been described to cause a syndrome of multisystemic smooth muscle dysfunction with an extremely characteristic cerebrovascular appearance.1 Accurate neuroimaging diagnosis of this entity is important as this syndrome predisposes to complications such as early-onset ischemic stroke and ascending thoracic aortic aneurysm.2,3 The following case demonstrates a previously undescribed ACTA2 mutation (Met46) with an identical cerebrovascular imaging appearance to that of Arg179 mutations, but a less severe overall phenotype.

Effect of socioeconomic status on patients undergoing elective abdominal aortic aneurysm repair in a publicly funded health care system
CONCLUSION: Socioeconomic status does not appear to affect short- or long-term mortality after AAA repair in a publicly funded health care system. Further research is needed to address any existing gaps in screening and referral before repair.PMID:36882205 | DOI:10.1503/cjs.015321
