2017-08-05

TIA: refers to the pre-thrombosis and other factors caused by the carotid artery or vertebral basilar artery system transient short-term cerebral blood supply disorders, resulting in limited blood loss of the blood supply area symptoms, each attack for several minutes to 1 hour, 24 hours of complete remission, intermittent period without any positive signs, often recurrent, more common in the elderly over the age of 50. The disease belongs to the traditional Chinese medicine "stroke aura, small stroke, small stroke" category. 
Clinical manifestations:

Internal carotid artery system TIA: partial body movement disorder; partial body sensory disturbance; monocular a transient black; a transient language barrier.

Vertebral basilar artery system TIA: dizziness, balance disorders, diplopia, dysphagia and dysarthria; cross dyskinesia and / or sensory disturbances;

Clinical examination:

1. Blood biochemistry: elevated blood lipids elevated blood sugar

2. Hemorheology: Whole blood viscosity increased plasma viscosity increased red blood cell positive index increased

Blood sedimentation rate increases fibrinogen content

3. Cervical CT / MRI: bone hyperplasia of the intervertebral space narrowing transverse protrusion smaller

4. Routine EEG: Some patients showed insufficient coronary insufficiency

5. brain CT / MRI: generally no obvious abnormalities, a few people can see small softening

6. EEG: more normal

Diagnosis points: whether the TIA should meet the following characteristics:

Sudden onset

2. brain or retinal focal ischemic symptoms;

3. The duration of transient, intrauterine arterial system TIA average episodes of 14 minutes, vertebrobasilar arterial system TIA average episodes of 12 minutes, more than 1 hour to ease, the longest no more than 24 hours.

4. complete recovery;

5. often repeated attacks.
