Endovascular Management of Tandem Occlusion Stroke Related to Internal Carotid Artery Dissection Using a Distal to Proximal Approach: Insight from the RECOST Study EXTRACRANIAL VASCULAR
CONCLUSIONS: Mechanical endovascular treatment of carotid artery dissection tandem occlusions is safe and effective compared with isolated anterior circulation occlusion stroke therapy. Hence, a more conservative approach with stent placement only in cases of circle of Willis insufficiency may be a reliable and safe strategy.

Multicentric Experience in Distal-to-Proximal Revascularization of Tandem Occlusion Stroke Related to Internal Carotid Artery Dissection INTERVENTIONAL
CONCLUSIONS: Endovascular treatment of internal carotid dissection–related tandem occlusion stroke using the distal-to-proximal recanalization strategy appears to be feasible, with low complication rates and considerable rates of successful recanalization.

Anterior Circulation Acute Ischemic Stroke Associated with Atherosclerotic Lesions of the Cervical ICA: A Nosologic Entity Apart ADULT BRAIN
CONCLUSIONS: Our study suggests that atherothrombotic tandem occlusions represent a peculiar and different nosologic entity compared with dissection-related tandem occlusions. This challenging cause of acute ischemic stroke should be differentiated from other etiologies in patient management in future prospective studies.

Cost and Utility of Routine Contrast-Enhanced Neck MRA in a Pediatric MRI Stroke Evaluation Protocol PEDIATRICS
CONCLUSIONS: In our large series, the addition of a routine contrast-enhanced neck MRA to our pediatric stroke MR imaging protocol was of extremely low yield. We believe the use of neck MRA should reasonably be limited to cases in which abnormalities are initially detected on standard brain sequences or to patients with atypical presentation or recurrent pathology.

Usefulness of cervical magnetic resonance imaging for detecting type A acute aortic dissection with acute stroke symptoms
Type A acute aortic dissection (TAAAD) sometimes presents with acute stroke-like symptoms. When intravenous tissue plasminogen activator (IV-tPA) therapy is considered for acute ischemic stroke, TAAAD must be excluded. Painless TAAAD presenting with acute stroke may be easily missed. Two cases of painless TAAAD presenting with acute stroke in which IV-tPA therapy was considered are reported. In these cases, cervical magnetic resonance angiography (MRA) was useful for detecting TAAAD, and IV-tPA therapy was canceled.

Intentional subintimal carotid stenting of internal carotid dissection in a patient with acute ischaemic stroke.
We report the case of a young woman with severe acute ischaemic stroke due to carotid artery dissection and intracranial embolism. After failure of endoluminal crossing of the dissected segment, intentional subintimal crossing with re-entry distally to the dissection was achieved and a stent was deployed. Then, middle cerebral artery thrombectomy was performed achieving good recanalisation. Acute thrombus formed in the bulged segment of the carotid stent and was managed with additional stent placement. The patient had a good clinical recovery. In selected cases, after failure of conventional techniques, subintimal recanali...

Etiologies of internal carotid artery pseudo-occlusions in acute stroke patients: what neurointerventionalists can expect.
Abstract In cases of acute stroke, differentiation between an occluded and a patent internal carotid artery (ICA) is crucial for diagnosis and management. Although computed tomography angiography (CTA) can be highly accurate in defining high-grade stenosis and ICA occlusions, misleading ICA occlusion patterns are not rare in acute stroke patients. We investigated the underlying causes of ICA pseudo-occlusions with CTA with respect to digital subtraction angiography (DSA). 11 out of 72 patients had pseudo-occlusion on CTA. Of these, there were three cases of tandem occlusions accompanying high-grade ICA stenosis, f...

Stenting of the cervical internal carotid artery in acute stroke management: The Karolinska experience.
Conclusions Our single-centre retrospective analysis of emergency stent placement in the extracranial internal carotid artery in combination with anterior circulation thrombectomy demonstrated high technical success, reasonable clinical outcomes and acceptable rates of symptomatic intracranial haemorrhage in carefully chosen patients which are triaged interdisciplinary based on clinical and computed tomography imaging criteria. This warrants further study in a randomised prospective trial. PMID: 28304205 [PubMed - in process]

Clinical and Imaging Characteristics of Arteriopathy Subtypes in Children with Arterial Ischemic Stroke: Results of the VIPS Study PEDIATRICS
CONCLUSIONS: Childhood arteriopathy subtypes have some typical features that aid diagnosis. Better imaging methods, including vessel wall imaging, are needed for improved classification of focal cerebral arteriopathy of childhood.

Mid-cervical flame-shaped pseudo-occlusion: diagnostic performance of mid-cervical flame-shaped extracranial internal carotid artery sign on computed tomographic angiography in hyperacute ischemic stroke
ConclusionThe mid-cervical flame-shaped extracranial ICA sign may suggest the presence of isolated intracranial ICA occlusion and allow reliable exclusion of tandem extracranial-intracranial ICA occlusion in hyperacute ischemic stroke setting.

Endovascular thrombectomy for tandem acute ischemic stroke associated with cervical artery dissection: a systematic review and meta-analysis
ConclusionsCurrent data suggest that endovascular thrombectomy may be an option in patients with acute ischemic stroke due to cervical artery dissection. This requires further confirmation in higher quality prospective studies.

The Dilator-Dotter Technique: A Modified Method of Rapid Internal Carotid Artery Revascularization in Acute Ischemic Stroke INTERVENTIONAL
CONCLUSIONS: The dilator-Dotter technique may be a safe and effective modification of the traditional Dotter technique in allowing rapid ICA recanalization in cases of acute ischemic stroke due to tandem occlusions.

Simultaneous revascularization of the occluded internal carotid artery using the Solitaire as a workhorse wire during acute ischemic stroke intervention.
CONCLUSION: As the management paradigms of tandem occlusions continue to evolve, this technique may improve outcomes by expediting endovascular intervention. Using the stent retriever wire provides a method of expediting the management of the proximal lesion after addressing the more distal intracranial occlusion first.

Prognosis of spontaneous cervical artery dissection and transcranial Doppler findings associated with clinical outcomes
Conclusions The outcome of sCAD depends on its radiological subtype. In the occlusive subtype, which is associated with the worst outcome, TCD flow analysis may predict acute stroke progression and long-term outcome. Key Points • Outcomes in cervical artery dissection may be determined by radiological subtypes. • The aneurysm and stenotic groups had favourable outcomes. • The occlusive group had less favourable functional outcomes. ...

Arterial tortuosity in patients with spontaneous cervical artery dissection
ConclusionCeAD patients exhibit increased arterial tortuosity. This might have potential implications for better understanding of the pathophysiology of the disease as well as clinical utility in evaluation, prognostication, and decision-making of affected individuals.
