Outcome estimation based on multimodal computed tomography examination in acute ischaemic stroke patients treated with mechanical thrombectomy.
Conclusions: There is no justification for the use of reperfusion procedures in acute ischaemic stroke in the anterior circulation in patients with initially unfavourable multimodal computed tomography scores. PMID: 31908703 [PubMed]

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.

Acute ischemic stroke: The role of emergency carotid endarterectomy in isolated extracranial internal carotid artery occlusion
CONCLUSIONS: Emergency CEA in isolated eICA occlusion has proved to be a safe and effective treatment option in selected patients. CT perfusion, imaging the ischemic penumbra and quantifying the tissue suitable for reperfusion, offers a valid support in the diagnostic-therapeutic workup. Indeed, we can infer that the area of the ischemic penumbra is directly proportional to the margin of clinical improvement after revascularization, supposing that the appropriate intervention timing is respect.PMID:37594376 | DOI:10.1177/17085381231192712

Very Early Carotid Endarterectomy After Intravenous Thrombolysis.
CONCLUSION: This experience suggests that very early CEA after thrombolysis, aimed at removing the source of potential embolisation and restoring blood flow, may be safe and can lead to a favourable outcome. PMID: 26712132 [PubMed - as supplied by publisher]

Displacement Forces in Iliac Landing Zones and Stent Graft Interconnections in Endovascular Aortic Repair: An Experimental Study.
CONCLUSIONS: Pulsatile flow through a tubular untapered stent graft causes forces of similar magnitude at both ends and induces pulsatile graft movements in its unsupported mid-section. Peak forces are close to those previously reported to be required to extract a stent graft. The forces and movements increase with increasing graft angulation and perfusion pressure. Improved anchoring of the distal end of stent grafts may be considered. PMID: 24445085 [PubMed - as supplied by publisher]

Displacement Forces in Iliac Landing Zones and Stent Graft Interconnections in Endovascular Aortic Repair: An Experimental Study
Objectives: Stent graft migration influences the long-term durability of endovascular aortic repair. Flow-induced displacement forces acting on the attachment zones may contribute to migration. Proximal fixation of aortic stent grafts has been improved by using hooks, while distal fixation and stent graft interconnections depend on self-expansion forces only. We hypothesized that flow-induced displacement forces would be significant at the distal end, and would correlate with graft movements.Methods: As part of an experimental study, an iliac limb stent graft was inserted in a pulsatile flow model similar to aortic in viv...

Low carotid stump pressure as a predictor for ischemic symptoms and as a marker for compromised cerebral reserve in octogenarians undergoing carotid endarterectomy
Carotid artery occlusive disease can cause stroke by embolization, thrombosis, and hypoperfusion. The majority of strokes secondary to cervical carotid atherosclerosis are believed to be of embolic etiology. However, cerebral hypoperfusion could be an important factor in perioperative stroke. We retrospectively reviewed the stump pressure (SP) of carotid endarterectomy (CEA) of patients at Pennsylvania Hospital to identify whether physiologic perfusion differences account for differences in perioperative stroke rates, particularly in octogenarians.

Longitudinal Evaluation of Neurobehavioral Outcomes After Carotid Revascularization
Conclusions: The relationship between carotid revascularization and cognitive function is complex, and cognitive deficits may occur in the presence of increased cerebral perfusion without detectable embolization.
