Todd's paralysis due to hyperperfusion syndrome after carotid endarterectomy mimicking postoperative stroke
J Cardiovasc Surg (Torino). 2023 Jun 19. doi: 10.23736/S0021-9509.23.12720-0. Online ahead of print.ABSTRACTTodd's paralysis is a neurological deficit that is observed in <10% of patients following epileptic seizures. Cerebral hyperperfusion syndrome (CHS) is a rare complication following carotid endarterectomy (CEA), seen in 0-3% of the patients, characterized by focal neurological deficit, headache, disorientation, and sometimes seizures. In this case report, we present a case of CHS after CEA followed by seizures and Todd's paralysis that mimicked postoperative stroke. A 75-year-old female patient was admitted for CE...

Characteristics of Ischemic Brain Lesions After Stenting or Endarterectomy for Symptomatic Carotid Artery Stenosis: Results From the International Carotid Stenting Study-Magnetic Resonance Imaging Substudy Original Contributions
Conclusions— Compared with patients undergoing CEA, patients treated with CAS had higher numbers of periprocedural ischemic brain lesions, and lesions were smaller and more likely to occur in cortical areas and subjacent white matter. These findings may reflect differences in underlying mechanisms of cerebral ischemia. Clinical Trial Registration— URL: http://www.isrctn.org. Unique identifier: ISRCTN25337470.

Clinical risk predictors for cerebral hyperperfusion syndrome after carotid endarterectomy
Conclusions Independent, prospective monitoring of a large cohort of CEA cases identified a brief time interval between ischaemic symptoms and endarterectomy as the clearest risk factor for CHS.

The Phenotype of Infiltrating Macrophages Influences Arteriosclerotic Plaque Vulnerability in the Carotid Artery
Conclusions: Our data show that M1 macrophage content of atherosclerotic plaques is associated with clinical incidence of ischemic stroke and increased inflammation or fibrinolysis. We also show the benefits of using ultrasound to evaluate vulnerability in the plaques.

Periprocedural Hemodynamic Depression Is Associated With a Higher Number of New Ischemic Brain Lesions After Stenting in the International Carotid Stenting Study-MRI Substudy Clinical Sciences
Conclusions— In patients treated by CAS, periprocedural hemodynamic depression is associated with an excess of new ischemic lesions on diffusion-weighted imaging. The findings support the hypothesis that hypoperfusion increases the susceptibility of the brain to embolism. Clinical Trial Registration— URL: http://www.controlled-trials.com. Unique identifier: ISRCTN25337470.

Predictors of Acute and Persisting Ischemic Brain Lesions in Patients Randomized to Carotid Stenting or Endarterectomy Brief Reports
Conclusions— Stenting caused more acute and persisting ischemic brain lesions than endarterectomy. However, the rate of conversion from acute to persisting lesions was lower in the stenting group, most likely attributable to lower acute lesion volumes.

Reperfusion Injury on Magnetic Resonance Imaging After Carotid Revascularization Brief Reports
Conclusions— HARM after carotid revascularization is not uncommon. Symptomatic HARM was associated with old age, underlying leukoaraiosis, and postprocedural high blood pressure.

Ischemic Stroke Predicts Myocardial Injury After Carotid Endarterectomy for Symptomatic Severe Carotid Artery Stenosis
Myocardial injury following carotid endarterectomy (CEA) is a common cause of morbidity and mortality, and its risk varies depending on the severity and extent of disease. However, when patients with sympotomatic severe carotid stenosis undergo CEA, the frequency and potential predictors of myocardial injury remain unknown. A total of 40 patients (32 men and 8 women) who underwent successful standard CEA were observed. Cardiac troponin I (cTnI) concentrations were assessed before surgery and on postoperative days 1, 2, and 3 in all patients. Myocardial injury was defined as the peak cTnI concentration > 0.04 ng/mL. In a...

Improvement of Cognitive Function after Carotid Endarterectomy—A New Strategy for the Evaluation of Cognitive Function
In conclusion, MoCA was feasible in patients soon after undergoing CEA. Using MoCA not MMSE, CEA may improve cognitive function in patients with significant carotid stenosis.

Risk Factors Associated With Cerebrovascular Recurrence in Symptomatic Carotid Disease: A Comparative Study of Carotid Plaque Morphology, Microemboli Assessment and the European Carotid Surgery Trial Risk Model Stroke
Conclusions The presence of carotid plaque hemorrhage is better associated with recurrent cerebrovascular events in patients with symptomatic severe carotid stenosis than the presence of microembolic signals; combining MES and MRIPH, further improves the association while the ECST risk score was insignificant.

Carotid plaque inflammation assessed with 18F‐FDG PET/CT is higher in symptomatic compared with asymptomatic patients
Conclusion18F‐FDG uptake on PET/CT correlated with histological assessments of inflammation and was higher in patients with symptomatic compared with asymptomatic carotid artery plaques. These results support the use of 18F‐FDG PET/CT in the detection inflammation in carotid atherosclerosis, which may be of help in the detection of vulnerable plaques.

Carotid revascularization treatment is shifting to low volume centers
Conclusions A trend toward a lower proportion of patients with carotid stenosis being treated in high volume centers from 2005 to 2011 is concerning as these high volume centers had lower complication rates.

Definite Plaque Echolucency is Associated with a Higher Risk of Ipsilateral Ischaemic Stroke during Early Follow up in the Asymptomatic Carotid Surgery Trial-1 (ACST-1)
Introduction: Several carotid plaque characteristics, including a thin fibrous cap, lipid necrotic core and intraplaque haemorrhage, have been suggested as potential markers to select patients at high risk for future stroke. On ultrasound, these “high risk” characteristics appear echolucent. The Asymptomatic Carotid Surgery Trial-1 (ACST-1) is the largest randomised controlled trial comparing carotid endarterectomy (CEA) with deferral of CEA in patients with severe asymptomatic carotid artery stenosis.
