Ultrasound Assessment of Internal Carotid Stenosis Pre- and Post-endarterectomy of Contralateral Near-occluded Carotid
Internal carotid artery (ICA) stenosis often presents bilaterally and is a major cause of stroke. Carotid duplex ultrasound is used for stenosis estimation via peak systolic velocity (PSV), end diastolic velocity (EDV), and ICA/common carotid artery (CCA) ratio. Carotid endarterectomy (CEA) is a common surgery for ICA stenosis and carries a high risk of stroke and mortality. In ICA near occlusion with>90% stenosis, collateral flow through contralateral ICA can compensate with increased velocities, artificially elevating contralateral stenosis.

Predictors of hemodynamic instability during and persistent after carotid artery stenting
Carotid artery stenting (CAS) is an alternative to carotid endarterectomy (CEA) and is widely used to treat carotid artery stenosis. CAS and CEA have been demonstrated to be equally effective and safe in both symptomatic and asymptomatic cases of carotid artery stenosis.1-3 CAS-induced hemodynamic instability (HI), manifested as bradyarrhythmia and/or hypotension, has been reported to have an incidence ranging from 7% to 76%.4-7 HI induced by CAS may increase the risk of perioperative cardiac and neurological events.

What Is the Role of Transcarotid Artery Revascularization?
Adv Surg. 2023 Sep;57(1):115-140. doi: 10.1016/j.yasu.2023.04.010. Epub 2023 May 26.ABSTRACTCarotid endarterectomy (CEA) is the gold-standard method of carotid revascularization in symptomatic patients with ≥50% and in asymptomatic patients with ≥70% stenosis. Transfemoral carotid artery stenting (TFCAS) has been associated with higher perioperative stroke rates compared to CEA in several studies. On the other hand, transcarotid artery revascularization (TCAR) has outperformed TFCAS in patients who are considered high risk for surgery. There is increasing data that supports TCAR as a safe and efficient technique with o...

Postoperative disability and one-year outcomes for patients suffering a stroke after carotid endarterectomy
Objective: Although post-carotid endarterectomy (CEA) strokes are rare, they can be devastating. The degree of disability that patients develop after such events and its effects on long-term outcomes are unclear. Our goal was to assess the extent of postoperative disability in patients suffering strokes after CEA and evaluate its association with long-term outcomes.

E-107 Carotid artery stenting in patients with symptomatic non-stenotic carotid artery disease - a case series
ConclusionsIn this case series performed over a 10-year period at a high-volume stroke center we show that CAS is safe and efficient in patients with SyNC. Previous studies have established safety and effectiveness of CES in patients presenting with SyNC, however there is a paucity of reports in the literature regarding the effect of CAS in this patient population. Recent guidelines have brought specific attention to high-risk plaque characteristics which suggest that plaque instability plays a major role in the onset of ischemic events, regardless of lumen narrowing. Advanced imaging techniques, such as Optical Coherence ...

Long Term Outcomes After Invasive Treatment of Carotid Artery Stenosis: a Longitudinal Study of German Health Insurance Claims
CONCLUSION: The current study revealed striking differences between previous landmark trials and real world practice. It further suggested excess mortality of invasively treated asymptomatic patients.PMID:37490978 | DOI:10.1016/j.ejvs.2023.07.030

Discharge prescription patterns for antiplatelet and statin therapy following carotid endarterectomy: an analysis of the vascular quality initiative
Conclusions Although statin use has substantially improved following CEA, more than half of individuals not on a statin preprocedure remained this way at discharge. In addition, DAPT at discharge was frequent, a quarter of whom were on SAPT preprocedure. Further efforts are needed to improve rates of new statin prescriptions, ensure appropriate APT intensity at discharge and determine how different discharge APT regimens impact outcomes.

Correlation Between Intracranial Calcification and Extracranial Stenosis of the Internal Carotid Artery
We examined a population not selected for cerebral disease. This retrospective study contained 179 subjects aged 18 years and older from the Hawaii Diagnostic Radiology database. Extracranial internal carotid artery stenosis was determined using the absolute diameter, North American Symptomatic Carotid Endarterectomy Trial, and common carotid artery methods. Calcification was scored using the modified Woodcock method. A positive correlation between intracranial calcification and extracranial carotid stenosis was found using all three methods. Individuals with intracranial calcification were more likely to be older, have a ...

Evidence of an anti-inflammatory effect of PCSK9 inhibitors within the human atherosclerotic plaque
CONCLUSIONS: The use of PCSK9 inhibitors is accompanied by a beneficial remodelling of the inflammatory burden within the human atheroma, an effect possibly or partly independent of their LDL-C lowering ability. This phenomenon might provide an additional cardiovascular benefit.PMID:37422356 | DOI:10.1016/j.atherosclerosis.2023.06.971

A comparative effectiveness study of carotid intervention for long-term stroke prevention in patients with severe asymptomatic stenosis from a large integrated health system
CONCLUSIONS: In this contemporary cohort study of patients with ACS utilizing rigorous analytic methodology, CEA appears to have a small but statistically significant effect on stroke prevention out to 8 years. Further study is needed to appropriately select the subset of patients most likely to benefit from intervention.PMID:37406943 | DOI:10.1016/j.jvs.2023.06.024
