Application of Multi Slice Spiral CT Combined with Head and Neck Digital Subtraction Angiography in the Diagnosis of Head and Neck Vascular Diseases

摘要

To evaluate the value of 128 slice spiral CT combined digital subtraction angiography in the diagnosis of head and neck vascular diseases. Materials and methods: from March 2016 to December 2016 during the screening in the Institute of clinical diagnosis of subarachnoid hemorrhage (21 cases), cerebral hemorrhage (15 cases), cerebral infarction (49 cases), transient ischemic attack (15 cases), frontal mass (1 cases), neck mass (2 cases) and accept the 128 slice CT digital subtraction angiography (DSCTA) in 103 cases of patients, the imaging data were retrospectively analyzed and compared with that of DSA. The head neck vascular diagnosis experienced 2 attending doctors to assess vascular imaging quality, vascular stenosis and plaque nature, aneurysm, arteriovenous malformation, vascular variation. Results: the neck vascular one or a plurality of different soft and hard plaque caused by different degree of luminal stenosis and occlusion (51 cases), abnormal blood vessels (16 cases), unilateral vertebral artery dysplasia (3 cases), aneurysm (22 cases), arteriovenous malformation (3 cases), carotid body tumors (2 cases), normal (6 cases). Conclusion 128 slice digital subtraction angiography (DSCTA) can effectively remove bone parts of vascular lesions, accurate clear images of size, shape and range and its relationship with the surrounding tissue for clinicians, and is non-invasive, rapid, simple, high safety and for head and neck vascular stenosis and soft plaque vascular variation, dysplasia, aneurysm, application of venous malformation diagnosis for accuracy, high reliability and clinical treatment is higher, it is worthy of popularization and application.
