Clot-based time attenuation curve as a novel imaging predictor of mechanical thrombectomy functional outcome in acute ischemia stroke
ConclusionsThrombus TAC on CTP were found to be a promising new imaging biomarker to predict the outcomes of MT in AIS.Clinical relevance statementThis study revealed that clot-based time attenuation curve based on admission perfusion CT could reflect the permeability and composition of thrombus and, also, provide valuable information to predict the clinical outcomes of mechanical thrombectomy in patients with acute ischemia stroke.Key Points• Two time-attenuation curves distributions achieved strong correlations (|r|= 0.627, p <  0.001) with histopathological results.• The unimodal time-attenuation curve was ...

Initial and follow-up high-resolution vessel wall MRI study of spontaneous cervicocranial artery dissection
ConclusionsMultiple initial factors were found to be related to stroke occurrence and anatomical outcomes of sCCAD. High-resolution VW-MRI may provide valuable insights into the pathophysiology and evolution of sCCAD.Clinical relevance statementInitial and follow-up high-resolution vessel wall MRI may help elucidate the pathophysiology of spontaneous cervicocranial artery dissection and provide important insights into the evolution and further facilitate the optimal management of patients with spontaneous cervicocranial artery dissection.Key Points•Clinical and imaging factors, as well as the status of primary collateral...

Endovascular repair combined with in situ fenestration for new ‐onset or residual arch dissection in patients underwent aortic replacement
ConclusionOur preliminary experience suggests that endovascular total arch repair combined with ISF technique is a viable, effective and safe option for treatment. Our mid-term results have been promising, but we acknowledge the need for further evaluation to assess long-term outcomes and durability.

Effect of mechanical thrombectomy with and without intravenous thrombolysis on the functional outcome of patients with different degrees of thrombus perviousness
ConclusionPatients with thrombi of lower perviousness were recommended to undergo intravenous alteplase followed by endovascular thrombectomy, and those with thrombi of higher perviousness could undergo thrombectomy alone.

Treatment of an Acute Common Carotid Artery Occlusion Using a Large-Bore Aspiration Thrombectomy Device
An 86-year-old man presented with acute ischemic stroke in the left middle cerebral artery territory due to complete occlusion of the left common carotid artery (CCA) extending into the left internal and external carotid artery up to the carotid terminus (C7) (Fig 1). The etiology was surmised to be cardioembolic, in the setting of atrial fibrillation with subtherapeutic anticoagulation (international normalized ratio, 1.8). After presentation, the National Institutes of Health Stroke Scale (NIHSS) score increased from 4 (baseline) to 8 points; mechanical recanalization by percutaneous thrombus aspiration was planned.

Insights into acute mesenteric ischaemia: an up-to-date, evidence-based review from a mesenteric stroke centre unit
Br J Radiol. 2023 Jul 26:20230232. doi: 10.1259/bjr.20230232. Online ahead of print.ABSTRACTRadiologists play a central role in the diagnostic and prognostic evaluation of patients with acute mesenteric ischaemia (AMI). Unfortunately, more than half of AMI patients undergo imaging with no prior suspicion of AMI, making identifying this disease even more difficult. A confirmed diagnosis of AMI is ideally made with dynamic contrast-enhanced CT but the diagnosis may be made on portal-venous phase images in appropriate clinical settings. AMI is diagnosed on CT based on the identification of vascular impairment and bowel ischae...

Multicenter comparison of antiplatelet treatment strategies for urgent/emergent neuroendovascular stenting
CONCLUSION: The optimal timing of antiplatelet administration in relation to stent placement and route of administration of antiplatelet agents is unclear. Timing and route of administration of antiplatelet agents may have an effect on thrombosis in emergent neuroendovascular stenting. Significant practice variation exists in antiplatelet agent utilization in emergent neuroendovascular stenting.PMID:37402388 | DOI:10.1177/15910199231180003

Predictive Ability Of More Than 3-day Pre-atrial Fibrillation Ablation Cardiac Computed Tomography In Detection Of Left Atrial Thrombus
Introduction: Several studies described the diagnostic accuracy of Cardiac Computed Tomography (CCT) with delayed phase in detection of LA/LAA thrombus. Pre-Atrial fibrillation ablation (AFA) CCT is primarily done for pulmonary vein mapping. CCT performed alone within 72 hours prior to AFA has been suggested to be an alternative to Transesophageal Echocardiography (TEE) to rule out LAA thrombus in the low-intermediate stroke risk patients.(1) Hounsfield Unit ratio (HU) of> 0.75 between left atrial appendage (LAA) and ascending aorta (AA) has been suggested as reliable indicator of absence of thrombus on CCT(2) However, pre...

Hemodynamic outcomes of stenting for vertebrobasilar insufficiency in patients with a low flow state
CONCLUSIONS: Our series demonstrates angioplasty and stenting significantly improve intracranial flow over long-term. Angioplasty and stenting may improve the natural history of low-flow VB atherosclerotic disease.PMID:37386804 | DOI:10.1177/15910199231185801
