cerebral arterial steal syndrome
Introduction
Introduction to cerebral arterial steal syndrome The cerebral arterial stagnation syndrome (stealsyndrome) is caused by various causes of severe stenosis and occlusion of the aortic arch and its adjacent aortic vessels. The pressure in the stenotic distal cerebral artery is significantly reduced, and other nearby cerebral arterial blood is caused by siphoning. The flow countercurrently supplies a lower pressure artery to compensate for its blood supply. The blood supply to the cerebral arteries was significantly reduced, and the corresponding symptoms of the brain tissue were found to be clinical signs and symptoms, called cerebral artery reflux syndrome. Including subclavian artery stealing blood syndrome, carotid steal syndrome, vertebral-basal artery steal syndrome. Severe ischemic symptoms may be considered for surgical treatment, such as endometrial ablation, endovascular stent or revascularization. It is not advisable to use vasodilators and blood pressure lowering drugs. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people. Mode of infection: non-infectious Complications: dizziness, nausea and vomiting, tinnitus, ataxia
Cause
Causes of cerebral arterial steal syndrome
Atherosclerosis is the most common cause of occlusion, and very few are congenital, rare in chest trauma, avascular disease, giant cell arteritis, embolism or tumor thrombus.
Prevention
Prevention of cerebral arterial steal syndrome
Early detection, early diagnosis, and early treatment are key.
Complication
Complications of cerebral artery steal syndrome Complications, dizziness, nausea, vomiting, tinnitus, ataxia
Symptoms of vertebral-basal arterial insufficiency are the most common and can be considered as secondary clinical manifestations of the disease.
Symptom
Symptoms of cerebral arterial steal syndrome Syndrome Common symptoms Dizziness, pale fainting, nausea, palpitations, tinnitus, ataxia, falls, episodes
Symptoms: dizziness, nausea, vomiting, tinnitus, limb paralysis, ataxia, etc., may have syncope episodes or falls. Suffering limb weakness, pale skin, cold, weight loss, numbness, etc.
Examine
Examination of cerebral arterial steal syndrome
The diagnosis of the lesion depends on angiography, CT, MRI. The clinical diagnosis is significantly weakened or disappeared according to the pulsation of the upper extremity artery of the affected side. The blood pressure is lower than the healthy side of 20 mmHg, the ipsilateral neck is squeaky and murmur, the blood vessel is narrowed or occluded by ultrasound, and the active limb can induce or aggravate the vertebral-basal Arterial insufficiency symptoms. The DSA examination found that the contrast agent was reversely flowed into the affected side of the blood vessel to confirm the diagnosis.
Diagnosis
Diagnosis and differentiation of cerebral arterial steal syndrome
diagnosis
Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.
Differential diagnosis
1. Coronary artery insufficiency: Coronary artery insufficiency is mainly caused by coronary atherosclerosis, but because it is mild, it has not caused symptoms, so it is easy to cause arteriosclerosis such as hypertension, hyperlipidemia, diabetes and smoking. It is directly related to the occurrence of this disease.
2. Cardiac neurosis: The patient often complains of pain in the precordial area, located at the apex of the apex or under the nipple, and the position is limited. It appears as acupuncture-like, lasting only a few seconds, with nitroglycerin ineffective or immediate "effective", or 10 minutes The above is "effective"; patients often have sigh breathing, palms and underarms sweating, palpitations, insomnia, inattention and so on.
