Noninvasive vascular imaging methods, such as ultrasound (US), magnetic resonance angiography (MRA) and computed tomography angiography (CTA) are increasingly replacing conventional angiography for the diagnosis of carotid and vertebral dissections. Ultrasound provides dynamic and “real-time” information ...
The aim of this study was to evaluate the true incidence of cervical artery dissections (CeADs) in trauma patients with an Injury Severity Score (ISS) of $16, since head-and-neck computed tomography angiogram (CTA) is not a compulsory component of whole-body trauma computed tomography (CT)...
The aim of this study was to evaluate the true incidence of cervical artery dissections (CeADs) in trauma patients with an Injury Severity Score (ISS) of ≥16, since head-and-neck computed tomography angiogram (CTA) is not a compulsory component of whole-body trauma computed tomography (CT)...
When a tear occurs in one of the major cervicocerebral arteries and allows blood to enter the wall of the artery and split its layers, the result is either stenosis or aneurysmal dilatation of the vessel. Vertebral artery dissection (VAD) is an infrequent occurrence but is a leading cause of...
Contrast extravasation (spot signs, SpS) on computed tomographic angiography (CTA) may be a promising method to predict hematoma expansion in acute SICH. However, prospective data on the predictive value of the SpS on hematoma expansion and clinical outcome are still limited. We aimed to ...
The Vertebral Artery is defined as a major blood vessel that is divided into four segments, extending from the subclavian artery to the foramen magnum, supplying the brain and deep neck muscles with oxygenated blood. AI generated definition based on: Imaging in Spine Surgery, 2017 ...
Objective To understand the features of CTA in normal and abnormal vertebral artery.To investigate the clinical value of angiography with CTA to TIA.Methods After peripherical intravenous administration of contrast agent,then to perform scaning of 23 normal and 41 patients with TIA or suspected and ...
Figure 1.CT shows the lacunar infarction of left thalamus. CTA images show left vertebral-basilar artery and ICA dissections/dissecting aneurysms, indicating the possibility of angio dysplasia.图 1. CT显示左侧丘脑腔隙性梗死。CTA显示左侧椎-基底动脉和颈内动脉夹层/夹层动脉瘤,血管发育不良。
nerve (asterisk) were identified through the right far-lateral transcondylar approach (D) The aneurysm clip was applied to the aneurysm neck (E) Operative field after aneurysm clipping (F) Postoperative CTA revealed complete aneurysm obliteration and good patency of the right vertebral artery. ...
