Traumatic vertebral artery injury: Denver grade, bilaterality, and stroke risk. A systematic review and meta-analysis
CONCLUSIONS: VAI complicates a small yet nontrivial fraction of blunt trauma cases, with Denver grade IV lesions being the most common. This is the first study to document a significantly higher stroke prevalence among grade III and IV VAIs compared with grade I and II VAIs independently from bilaterality. Bilateral VAIs carry a significantly higher stroke rate.PMID:37548568 | DOI:10.3171/2023.5.JNS222818

Timing and mechanism of ischemic stroke due to extracranial blunt traumatic cerebrovascular injury.
Conclusions Most ischemic strokes due to TCVI are embolic in nature and occur prior to screening CTA and initiation of treatment with aspirin. PMID: 23216467 [PubMed - as supplied by publisher]

The frequency of postoperative stroke in moyamoya disease following combined revascularization: a single-university series and systematic review.
Conclusions This experience of 358 consecutive procedures is one of the largest series for which the postoperative stoke rate for direct/combined bypass performed with a unified strategy has been reported. A systematic review confirmed that the postoperative stroke rate for the direct/combined procedure was comparable to that for the indirect procedure.

Severe carotid stenosis and delay of reperfusion in endovascular stroke treatment: an Interventional Management of Stroke-III study.
CONCLUSIONS Severe ipsilateral ICA stenosis was associated with a significantly longer time to reperfusion in the IMS-III trial. Although these findings may not translate directly to modern devices, this 28-minute delay in reperfusion has significant implications, raising concern over the treatment of tandem ICA stenosis and downstream large-vessel occlusion.

64-detector CT angiography within 24 hours after carotid endarterectomy and correlation with postoperative stroke.
CONCLUSIONS CTA within 24 hours of CEA demonstrates characteristic anatomical findings. CCA step-offs and ECA flaps are relatively common and clinically insignificant, whereas ICA/CCA flaps and thrombi are less frequently seen and are associated with postoperative stroke/TIA.

Aspirin for primary prevention of stroke in traumatic cerebrovascular injury: association with increased risk of transfusion.
CONCLUSIONS Treatment with aspirin for the prevention of stroke in patients with initially asymptomatic TCVI carries a significantly increased risk of PRBC transfusion. Future studies are needed to determine if this risk is offset by a reduced risk of ischemic stroke. PMID: 29775142 [PubMed - as supplied by publisher]

Topographic correlation of infarct area on CT perfusion with functional outcome in acute ischemic stroke.
CONCLUSIONSThe results of this study provide evidence that several CTP parameters are independent predictors of functional outcome in patients with AIS and have potential to identify those patients most likely to benefit from reperfusion therapy in the treatment of AIS.

Vessel perforation during withdrawal of Trevo ProVue stent retriever during mechanical thrombectomy for acute ischemic stroke.
Abstract The authors report a case of an intracranial extravasation during the withdrawal of a Trevo ProVue stent retriever device in a patient being treated for acute ischemic stroke. An 82-year-old woman developed sudden left hemiparesis and aphasia during an urgent cardiac catheterization procedure for a non-ST elevation myocardial infarction. She had a baseline National Institutes of Health Stroke Scale (NIHSS) score of at least 10 and no improvement with intravenous administration of tissue plasminogen activator (tPA). Cerebral angiography was performed with conscious sedation, confirming an occlusion of the ...

Blunt traumatic occlusion of the internal carotid and vertebral arteries.
Conclusions At the authors' institution, traumatic ICA occlusion is rare but associated with a high stroke rate. Robust collateral circulation may mitigate its severity. Embolic monitoring with TCD ultrasonography and prophylactic antiplatelet therapy should be used in all ICA Biffl Grade IV injuries. Unilateral VA Biffl Grade IV injury is the most common type of traumatic occlusion and is associated with significantly less morbidity. Embolic monitoring using TCD and prophylactic antiplatelet therapy do not appear to be beneficial in patients with traumatic VA occlusion. PMID: 24678781 [PubMed - as supplied by publisher]

Bypass surgery versus medical treatment for symptomatic moyamoya disease in adults.
CONCLUSIONS During the treatment of symptomatic MMD in adults, bypass surgery reduces stroke recurrence for the hemorrhagic type, but it does not do so for the ischemic type. The best choice of bypass methods in adult patients with MMD is uncertain. In adult ischemic MMD, a prospective randomized study to evaluate the effectiveness and safety of bypass surgery to prevent recurrent stroke is necessary.

Morphological characteristics of symptomatic and asymptomatic carotid webs
CONCLUSIONS: Patients with CWs that occupy more than half of the diameter of the carotid bulb lumen and are situated at acute angles relative to the carotid wall are more likely to present with acute ischemic stroke. Additional studies are needed to determine the long-term outcomes of these lesions.PMID:35426815 | DOI:10.3171/2022.2.JNS212310
