What is the most common complication of carotid stenting?
Symptomatic distal embolisation is the most frequent and important complication of CAS (1,2). It is caused by the release of material (thrombotic, necrotic, or atherosclerotic) from the site of the lesion during the intervention (7,8,14).
What happens if the left vertebral artery is blocked?
If the resulting loss of brain function is permanent, it’ s called a stroke (an infarction or brain attack). A stroke can either be caused by blockage in the vertebral or basilar artery or the breaking off of a piece of plaque (embolus) that travels downstream and blocks a portion of the blood flow to the brain.
Can you stent the vertebral artery?
Vertebral stenting has been widely used to treat symptomatic vertebral stenosis, but whether it reduces the frequency of recurrent stroke is uncertain. Randomised controlled trials comparing stenting with medical treatment were identified in the scientific literature.
What part of the brain does the vertebral artery supply?
Paired vertebral arteries provide blood supply for the upper part of the spinal cord, brainstem, cerebellum, and posterior part of the brain.
What is the treatment for vertebral artery occlusion?
Percutaneous angioplasty and stenting for the treatment of extracranial vertebral artery (VA) stenosis seems a safe, effective and useful technique for resolving symptoms and improving blood flow to the posterior circulation, with a low complication rate and good long-term results.
How important is the vertebral artery?
What is the purpose of the vertebral arteries? The vertebral arteries are part of the circulatory system. They carry blood to the brain and spinal cord, which are part of the nervous system. The vertebral artery provides 20% of blood flow to your brain (the carotid artery supplies the other 80%).
What can go wrong with stents?
damage to the artery where the sheath was inserted. allergic reaction to the contrast agent used during the procedure. damage to an artery in the heart. excessive bleeding requiring a blood transfusion.
What problems can a stent cause?
Stent related complications are primarily mechanical; including stent migration, encrustation, stone formation and fragmentation. Stents act as foreign bodes and may cause urinary tract infection, pyonephrosis that may lead to nonfunctioning kidney.
