Eye deviation on CT brain is strongly associated with LVO. Presence of eye deviation on CT should alert clinicians to probability of LVO and for formal angiographic testing if not already performed.

2019年8月1日 · Radiological eye deviation is a strong predictor of LVO in AIS patients treated with IV thrombolysis. CTA is the most widely performed imaging modality to detect LVO but as barriers to CTA access persist in some settings additional methods to predict LVO such as radiological eye deviation may be clinically useful.

This study demonstrates that LVO status in thromboly-sis eligible AIS patients can be predicted with high speci-ficity and positive predictive value in the presence of radiological eye deviation on acute CT brain. The sensitiv-ity and specificity for LVO prediction using radiological eye deviation was 71% and 77.5% respectively. Other

Hyperdense vessel sign (HVS) and more recently conjugate eye deviation on CT brain have been associated with LVO. Eye deviation and HVS were examined by non-radiologists to determine predictive value for LVO. Methods Presence of radiological eye deviation and HVS were examined on brain CT for stroke patients with baseline CT angiography.

2018年5月17日 · Over the last three years, we have seen the rise of neurointerventional therapies for patients with ischemic strokes due to large vessel occlusions (LVOs). This group of strokes typically includes patients with occlusion of the distal intracranial carotid artery, middle cerebral artery or anterior cerebral artery.

The radiological conjugate eye deviation (RCED) has been demonstrated as a NCCT sign to predict acute ischemic stroke (AIS) or AIS secondary to large vessel occlusion (LVO) in recent studies. We performed a meta-analysis to gain a better understanding into the predictive role of RCED for AISs and LVO-AISs.

2018年8月13日 · The strong evidence for the benefits of endovascular therapy (EVT) in patients with acute ischemic stroke (AIS) and large vessel occlusion (LVO) is changing the face of prehospital systems. 1,2 EVT may offer a longer time window and higher rate of complete reperfusion than intravenous tissue-type plasminogen activator therapy. 3,4 The ...

A smartphone pupillometer was used in AIS patients with LVO pre-mechanical thrombectomy, immediately post-thrombectomy, and at 24 h post-thrombectomy. Clinical and demographic data were collected, along with the proprietary Neurological Pupil index (NPi) score from the NPi-200 digital infrared pupillometer.

They found that subjective visual detection of radiographic eye deviation on nonenhanced computed tomography (NECT) brain is strongly associated with large vessel occlusion (LVO). This compelling association may expedite patients for timely angiographic testing and endovascular therapy.

2022年1月5日 · Large vessel occlusion (LVO) is the obstruction of large, proximal cerebral arteries and accounts for 24–46% of acute ischaemic stroke (AIS), when including both A2 and P2 segments of the anterior and posterior cerebral arteries (1).
