Moncler sales, Transcranial Doppler ultrasound observation of 260 cases of vertebral-basilar artery transient ischemic attack patients' risk factors for recurrence. Tubes. Suspected VBI patients should undergo routine TCD examination. In elderly people, vertebral-basilar artery TIA system frequently occurs, with signs and symptoms only appearing during attacks and all subsiding within 24 hours after the attack. Due to the lack of sensitive diagnostic methods for this disease, using brain CT, MRI, and other tests are both expensive and have a low positive rate; cerebrovascular angiography causes pain to patients and carries some risks. The advent of TCD provides a non-invasive screening method for studying intracranial arterial hemodynamics with a high detection rate, simple operation, repeatability, and the ability to conduct continuous dynamic observations of intracranial hemodynamics, which has higher clinical value and should be widely applied.
