Association of contrast enhancement of proximal internal carotid artery wall and champagne bottle neck sign with ipsilateral stroke in moyamoya disease patients.

With a champagne bottle neck sign, we will investigate the proximal internal carotid artery and their relationships with ipsilateral intracranial stroke in sufferers of moyamoya disease sufferers of moyamoya disease. Twelve patients with MMD had bilateral CBNS, and fourteen patients without CBNS were among the 44 patients with MMD. In arteries with CBNS, the proximal ICA had a smaller diameter, the maximum wall thickness of the proximal ICA was thicker, and arterial wall contrast enhancement was more common. AUC of the wall expansion of the proximal ICA with CBNS was 0. 79. The proximal ICA with CBNS has been specifically linked to intracranial stroke in the ipsilateral hemispheres of patients with MMD, particularly those with multiple lesions.

Studying plaque characteristics in extracranial carotid artery disease using CT angiography - Risk predictors beyond luminal stenosis.

The literature on CT angiography [CTA] to investigate plaque morphology [CTA] is limited. To determine the high risk characteristics beyond luminal stenosis, we investigated plaque characteristics of extracranial carotid arteries using CTA. Materials and methods The retrospective study design was developed based on medical records, and patients with carotid territory ischemia who underwent CTA from January 2011 to December 2015 were recruited from medical records. A cut-off value for soft plaque thickness of 2. 75 mm could predict symptomatic carotid disease with a sensitivity of 85. 2 % and specificity of 68. 0 percent [Youden's index]. Conclusions and Conclusions based on the percentage stenosis, the studied CTA plaque thickness showed an independent predictor of symptomatic disease irrespective of the type of plaque thickness. Soft plaque thickness over 2. 75 mm and the smallest detectable change[4 mm] are two new steps to help determine the risk of ischemic events in carotid atherosclerotic disease.
