Cervical spondylosis of vertebral artery with transcranial Doppler ultrasound analysis of test results


Embolization can provide a more precise diagnosis is based,[link widoczny dla zalogowanych], and possessed with or without trauma, repeatable operation,[link widoczny dla zalogowanych], low cost and other obvious advantages. In this paper, 100 cases of routine TCD detection of patients with CSA,[link widoczny dla zalogowanych], 63. O% CSA usually manifested in patients with different blood flow velocity increased,[link widoczny dla zalogowanych], decreased, both showed abnormal bilateral blood flow velocity,[link widoczny dla zalogowanych], but also showed unilateral abnormal blood flow velocity, and the CSA group, the abnormal rates of blood flow velocity control group (P <0.01). Cervical spondylosis of vertebral artery blood flow velocity in order to slow down as the most common, common cause for the proliferation and Luschka joint bone protruded disc compression vertebral artery, causing vertebral artery stenosis, and blood flow slows down; followed by abnormal blood flow velocity increased common reason for partial bone hyperplasia, resulting in changes in the microenvironment surrounding tissue, and stimulate the vertebral artery caused by blood flow to speed; also showed asymmetrical bilateral blood flow velocity, but more rare, mainly due to bilateral lesions asymmetry, or with contralateral vertebral artery and basilar artery compensatory self-compensatory regulation. Observations, routine TCD detection of CSA in patients with clinically typical blood flow velocity can be expressed as normal, neck rotation test done before the abnormal blood flow velocity found in the observation of routine testing in the CSA group, 37 cases of vertebral a no abnormal basilar artery flow velocity and further neck rotation test, the performance of abnormal blood flow velocity, flow velocity anomaly rate. This routine TCD examination to detect the neutral position at rest on the general state, the side of the vertebral artery blood flow is temporarily reduced, the other side of the filling can be compensated to the BA, neck rotation, the rotation of the vertebral artery by C Section pressure, leading to insufficient blood supply VA, and induced vertigo. LIN all were 100 cases of CSA and 50 healthy subjects were also found in patients with routine TCD detection of abnormal posture detection rate of 62%, abnormal neck rotation position detection rate was 96%, similar to the results of this article. Therefore, routine testing of negative, and can not rule out the disease in patients with dizziness is not caused by CSA, plus do neck rotation test helpful in the diagnosis of vertebral artery spasm and narrow. TCD can be directly on the vertebral basilar artery of a hemodynamic monitoring system, which is the study of cervical spondylosis of vertebral artery is an effective means of cerebral blood flow with the usual maps, color Doppler ultrasound, x-ray film, x-ray examination of vertebral artery angiography, Digital subtraction angiography, CT, magnetic resonance angiography compared with intuitive, economic, non-invasive, etc., for the operation of experienced researchers, their test results and X-ray, MRI and so there is a high degree of consistency, by turning neck bit CSA TCD detection can greatly improve the positive rate.
