Carotid artery stenosis, an underestimated cause of stroke recurrence in patients with ischaemic monocular visual loss.
CONCLUSIONS: Carotid stenosis ≥ 50% is present in patients with ocular ischaemia in approximately 20% of those with persistent visual loss and in 10% with transient visual loss. Those with carotid stenosis have a higher risk of stroke recurrence and should be considered urgent surgical intervention as other forms of stroke. PMID: 31155910 [PubMed - as supplied by publisher]

A Clinical Validation Study of Anatomical Risk Scoring for Procedural Stroke in Patients Treated by Carotid Artery Stenting in the International Carotid Stenting Study.
CONCLUSIONS: No statistically significant association was found between anatomical difficulty, as defined in the DAR score, and procedural stroke risk. However, the small sample size potentially rendered the study underpowered to detect group differences, and confirmation with a larger sample is essential.

Postoperative Stroke After Type A Aortic Dissection Repair: Hemorrhage Versus Ischemia
ConclusionsPostoperative hemorrhagic stroke was associated with poorer neurological outcomes and lower survival rates than those with ischemic stroke. Patients who have complex arch replacement, long cardiopulmonary bypass and aortic clamping times are at risk for postoperative hemorrhagic stroke and should have intensive neurological surveillance for early diagnosis and treatment after ATAAD repair surgery.

Evaluation of the association between the internal carotid artery and vertebral artery tortuosity and acute ischemic stroke using tortuosity index
CONCLUSIONS: This study showed that tortuosity of extracranial portions of the internal carotid and vertebral artery could be an independent imaging predictor of acute ischemic stroke in anterior and posterior circulation territories, respectively.PMID:36395481 | DOI:10.1177/17085381221140163

Carotid endarterectomy: the change in practice over 11  years in a stroke centre
ConclusionThe trends in CEA practice at our centre align with international trends and guidelines. This study provides a representative indicator of Australian hospital practice, and illustrates how evidence from research is translated into clinical care.

CT Perfusion Imaging in the Selection of Acute Stroke Patients to Undergo Emergent Carotid Endarterectomy
Severe acute stroke patients with critical carotid stenosis or occlusion without intracranial thrombus typically do not undergo emergent carotid thromboendarterectomy (CEA) because of the risk of reperfusion-related intracranial hemorrhage. Past studies have not consistently demonstrated benefit of early operative intervention. Cerebral computed tomography (CT), cervical and cerebral CT angiography (CTA), and cerebral CT perfusion (CTP) imaging may identify a subset of acute stroke patients without intracranial thrombus who may benefit from emergent CEA.

Cryptogenic Stroke Following Abdominal Free Flap Breast Reconstruction Surgery
Conclusion Surgeons and cardiologists should be aware of this cerebrovascular complication secondary to PFO following major reconstructive surgery such as microvascular breast reconstruction. It also serves to challenge microvascular surgeons to reconsider routine use of central venous pressure lines in free flap patients who might otherwise have good peripheral vessels for postoperative fluids and antibiotic administration.

Acute Isolated Mesenteric Artery Dissection: Four-Year Experience from a French Intestinal Stroke Center
CONCLUSION: Although IMAD was associated with a high frequency of AMI, a standardized protocol allowed a low rate of intestinal resection. In types I/II patients, a conservative therapy seems appropriate whereas in type III patients, urgent SMA revascularization should aim to avoid intestinal resection or death..PMID:36075544 | DOI:10.1016/j.ejvs.2022.08.032

Using a CT Angiography Artificial Intelligence Carotid Plaque Morphology Model to Predict Stroke
The gold standard for determining carotid artery stenosis is to calculate stenosis using the North American Symptomatic Carotid Endarterectomy Trial criteria and ultimately plan for medical vs surgical management based on percent stenosis and symptomatic status. Few studies have assessed plaque morphology as an additive tool for stroke prediction. Our study uses an artificial intelligence software in conjunction with a patient's computed tomography (CT) scan of the neck to create a three-dimensional (3D) model of the carotid artery and assess plaque morphology including calcification, intraplaque hemorrhage, matrix, and pe...

Locoregional anaesthesia and intraoperative angiography in carotid endarterectomy - 16-year results of a consecutive single-centre series
CONCLUSIONS: These data demonstrate a decline in the combined rates of any in-hospital major stroke or death after non-emergent CEA over time. Locoregional anaesthesia and intraoperative quality control were associated with these improvements and might be worthwhile in elective CEA.PMID:36229016 | DOI:10.1016/j.ejvs.2022.10.002

Subclavian revascularization in the age of thoracic endovascular aortic repair and comparison of outcomes in patients with occlusive disease
Conclusions: Stroke risk in this contemporary series of C-SBP/ST performed for TEVAR and OD indications may be higher than previously reported in historical series. In TEVAR patients, this may be attributed to procedural complexity of the TEVAR in patients requiring subclavian revascularization. In OD patients, this is likely due to the changing patient population that requires more frequent concomitant carotid interventions. Despite the short-term morbidity, excellent bypass durability and equivalent long-term patient survival can be anticipated.
