Relevance of Infarct Size, Timing of Surgery, and Peri-operative Management for Non-ischaemic Cerebral Complications After Carotid Endarterectomy
CONCLUSION: Infarct size and unintended high peri-operative blood pressure may increase the risk of non-ischaemic complications at CEA independently of whether performed early or delayed.PMID:34872814 | DOI:10.1016/j.ejvs.2021.09.044

Effects of different types of carotid endarterectomy on the course of resistant arterial hypertension
CONCLUSION: Classical CEE and glomus-sparing CEE techniques make it possible to achieve a stable target SBP level in patients with RAH as a result of CG preservation. Removal or traumatization of the latter during eversional CEE, the formation of a new bifurcation, autoarterial reconstruction is accompanied by the development of labile hypertension, an increase in the degree of hypertension and a high risk of hemorrhagic transformation in the brain. Thus, the most effective and safe types of CEE in the presence of RAH are classical CEE with plasty of the reconstruction zone with a patch and glomus-sparing CEE, accompanied ...

Features of Unstable Carotid Plaque During and After the Hyperacute Period Following TIA/Stroke
Conclusion: Patients undergoing surgery ≤14 days had a significantly higher overall burden of high risk plaque features compared with those undergoing delayed CEA. However, the secondary upsurge across a range of unstable plaque features in patients undergoing CEA after ≥29 days had elapsed suggests that the relationship between recency of symptoms and plaque histology is more complex than had been anticipated in previous studies.

The role of completion imaging following carotid artery endarterectomy
A variety of completion imaging methods can be used during carotid endarterectomy to recognize technical errors or intrinsic abnormalities such as mural thrombus or platelet aggregation, but none of these methods has achieved wide acceptance, and their ability to improve the outcome of the operation remains a matter of controversy.It is unclear if completion imaging is routinely necessary and which abnormalities require re-exploration. Proponents of routine completion imaging argue that identification of these abnormalities will allow their immediate correction and avoid a perioperative stroke. However, much of the evidenc...

Teaching NeuroImages: Perfusion imaging of cerebral hyperperfusion syndrome following revascularization
A 69-year-old man developed acute-onset confusion and hypertension with systolic pressures in the 160s 1 day after carotid endarterectomy for right facial droop from left hemispheric lacunar infarcts. CT perfusion (figure, A–D) demonstrated findings consistent with cerebral hyperperfusion syndrome (CHS) following revascularization. CHS is caused by loss of autoregulation, hypertension, and ischemia-reperfusion injury resulting in increased regional blood flow and vascular congestion.1 CHS following revascularization may present as ipsilateral headache, focal seizure, or neurologic deficit. Nonperfusion imaging may sh...

Identification of Patients with a Histologically Unstable Carotid Plaque Using Ultrasonic Plaque Image Analysis.
CONCLUSIONS: Computerized plaque analysis has the potential to identify patients with histologically unstable carotid plaques. This model requires validation, but offers the potential to influence patient selection for emergency interventions and the monitoring of medical therapy.

Identification of Patients with a Histologically Unstable Carotid Plaque Using Ultrasonic Plaque Image Analysis
Objectives: In patients with carotid stenosis the risk of stroke is highest in the first few days after onset of symptoms and it is low in asymptomatic patients. The ability to identify patients with a high (or low) probability of having a histologically unstable plaque might become a complimentary method that can refine the indications for surgical intervention.Methods: Two histopathologists, using validated American Heart Association criteria, independently graded plaques harvested during carotid endarterectomy. Preoperative Duplex images were independently assessed for juxtaluminal black area, plaque type, plaque area, ...

Emergent intracranial surgical embolectomy in conjunction with carotid endarterectomy for acute internal carotid artery terminus embolic occlusion and tandem occlusion of the cervical carotid artery due to plaque rupture.
Abstract Acute internal carotid artery (ICA) terminus occlusion is associated with extremely poor functional outcomes or mortality, especially when it is caused by plaque rupture of the cervical ICA with engrafted thrombus that elongates and extends into the ICA terminus. The goal of this study was to evaluate the efficacy and safety of surgical embolectomy in conjunction with carotid endarterectomy (CEA) for acute ICA terminus occlusion associated with cervical plaque rupture resulting in tandem occlusion. A retrospective review of medical records was performed. Clinical and radiographic characteristics were eval...

Carotid artery stenosis with a high-intensity signal plaque on time-of-flight magnetic resonance angiography and association with evidence of intraplaque hypoxia.
CONCLUSIONS Plaques with high-intensity signals on TOF MRA were associated with IPH and evidence of intraplaque hypoxia. This fact may represent an opportunity to establish novel therapeutic agents targeting intraplaque hypoxia. PMID: 27367236 [PubMed - as supplied by publisher]

Pathophysiology and management of reperfusion injury and hyperperfusion syndrome after carotid endarterectomy and carotid artery stenting
AbstractCerebral hyperperfusion is a relatively rare syndrome with significant and potentially preventable clinical consequences. The pathophysiology of cerebral hyperperfusion syndrome (CHS) may involve dysregulation of the cerebral vascular system and hypertension, in the setting of increase in cerebral blood flow. The early recognition of CHS is important to prevent complications such as intracerebral hemorrhage. This review will focus on CHS following carotid endarterectomy and carotid artery stenting. We will discuss the typical clinical features of CHS, risk factors, pathophysiology, diagnostic modalities for detecti...

Successful Emergency Carotid Endarterectomy after Thrombolysis with Intravenous Recombinant Tissue-Type Plasminogen Activator.
Authors: Yamamoto Y, Okazaki T, Yoda K, Tada Y, Nagahiro S Abstract Acute internal carotid artery (ICA) occlusion may result in severe disability or death. Revascularization by carotid artery stenting after treatment with intravenous (iv) recombinant tissue-type plasminogen activator (rt-PA) has been documented. However, there are few reports on emergency carotid endarterectomy (CEA) within 24 hours after the iv administration of rt-PA. We treated a 58-year-old man with right ICA occlusion with iv rt-PA. Although partial recanalization of the ICA was obtained, severe stenosis at the origin of the ICA persisted and ...

Chapter 31 Neurologic complications of cardiac and vascular surgery
Publication date: 2017 Source:Handbook of Clinical Neurology, Volume 141 Author(s): K.N. Sheth, E. Nourollahzadeh This chapter will provide an overview of the major neurologic complications of common cardiac and vascular surgeries, such as coronary artery bypass grafting and carotid endarterectomy. Neurologic complications after cardiac and vascular surgeries can cause significant morbidity and mortality, which can negate the beneficial effects of the intervention. Some of the complications to be discussed include ischemic and hemorrhagic stroke, seizures, delirium, cognitive dysfunction, cerebral hyperperfusion syndrome,...
