16 cases of basilar artery syndrome diagnosis

Bilateral brain stem, cerebellum, vermis infarction in 3 cases, the left cerebellar hemisphere, left temporal occipital lobe infarction in 1 case; bilateral thalamus infarction in 4 cases, including with the cerebellum, brainstem infarction in 3 cases. , J, brain, brain stem, temporal, occipital lobe infarction in 1 case; temporal occipital lobe, 4 cases of cerebellar infarction; cerebellum, brain stem and cerebellum, brain stem, temporal occipital lobe infarction in 1 patient each. 4. Treatment of cerebral ischemia treated according to the principle of promoting blood circulation to drugs, energy station agent, brain cell protective agent, dehydration reduce intracranial pressure and other treatment. 2 patients died of cerebral hernia condition worsened, and 1 discharged (follow-up after the death 2d); the other l3 patients discharged from hospital 21 ~ 80d,[link widoczny dla zalogowanych], efficacy assessed as significant progress in 3 cases, improvement in 6 cases, no change in 4 cases. Discuss the various causes of basilar artery regional blood circulation disorders, may lead to a sudden disturbance of consciousness, pupil and eye movement abnormalities as the main clinical manifestations of the 'lOBS. Cause 'lOBS main cause of cerebral embolism, accounting for 73% of this information, including atrial fibrillation in 11 cases, acute onset were dynamic, it is due to embolism, and Sato reported similar; followed by cerebral thrombosis, cerebral aneurysms, etc. . Similar risk factors and stroke. As often as part of the artery occlusion, can be expressed as the corresponding symptoms, then these vessels have been blocked may continue to the emergence of new symptoms, so complex and diverse clinical manifestations. Such as (1) disturbance of consciousness: including deep coma, decorticate rigidity, ataxia, of silence, the desire to lower or sleep over and so on. This data 81% of patients with different degrees of consciousness, of which 4 cases were unconscious, when the disease occurred in 3 cases a transient disturbance of consciousness, lethargy 6 patients, the prevalence rate consistent with the reported basic .... The mechanism was mainly due to the ascending reticular activating system in brain function is impaired. (2) pupillary abnormalities and eye movement disorders: When the basilar artery blood circulation disorders caused aqueduct oculomotor nuclei where the medial ventral tegmental ischemic brain, the pupil reflex arc transmission fiber in the optic tract to the eye Vice-nuclear section of nerve damage, often appear abnormal pupil, such as the pupil is not round, oculomotor nuclear involvement was manifested as vice mydriasis, light reflex disappeared. Eye movement disorder caused mainly by the bilateral oculomotor nerve palsy, the majority of incomplete paralysis, depending on the performance of the eyes can not, under visual barriers, one or both eyes Zhejiang Medicine 2 (] O1 23 years down the No. 9 attention, such as the oblique side. This information has pupil abnormalities in 6 cases, 12 cases of eye movement disorders, ptosis in 2 cases. (3) visual disturbances and abnormal behavior: This information appears as an illusion in 3 cases, 1 case to see people on the wall walked back and forth repeatedly. For the visual hallucinations of the lesion, it was considered in the cerebral peduncle, cerebral peduncle as illusion. As some patients with abnormal behavior, bizarre answer strange, far away from reality, irrelevant answers, this is a species of special form of fiction. (4) involuntary movements: the performance of a dance-like movements, resting tremor, throwing disorder side of the body, the Department of brainstem infarction involving the first-side red nucleus or the subthalamic nucleus result, the majority of the disease appear slowly after , occur in the face, arm and thumb. This information unilateral chorea in 2 cases, 1 case of upper limb rest tremor. 'lOBS scan head is the biggest characteristic bilateral symmetry into a butterfly hypothalamus low density lesions in the brain also can be found in the foot , midbrain, cerebellum, occipital lobe, temporal lobe infarction. ... This data cranial CT findings in 16 cases were abnormal, and Nit of the midbrain, cerebellar lesions, especially in the early onset of higher resolution. In addition, the vertebral artery angiography can understand basilar artery stenosis and occlusion of the neck and re-pass situation. this information on 2 patients with double-consciousness ranging from large pupil, was misdiagnosed as cerebral herniation, this is the identification of clinical work should pay attention to the point. when patients have high blood pressure or heart disease, sudden disturbance of consciousness, with pupil abnormalities, oculomotor nerve palsy, vertical gaze disorder, without significant motor or sensory disorders, in particular bilateral oculomotor nerve paralysis, should be thought of TOBS possible. Also still need and the arachnoid The following hemorrhage, identification of vertebrobasilar insufficiency. TOBS poor prognosis. this information in 2 deaths in 16 cases, efficiency 56.25%. Early diagnosis, proper and timely treatment, may improve the prognosis. reference to the text He 1cPLR.
