What is vertebrobasilar dolichoectasia?
Vertebrobasilar dolichoectasia is a neurological condition that is characterized by an abnormal enlargement of the artery walls due to weakened or stretched musculature. It is most commonly seen in the vertebrobasilar arteries, which are the major arteries that run through the neck and supply blood to the brain stem, cerebellum, and posterior fossa. This condition can cause a variety of symptoms, including headaches, vertigo, tinnitus, and ischemic stroke. It is typically diagnosed using magnetic resonance angiography or computed tomography angiography. Treatment options include antithrombotic therapy, endovascular embolization, and surgical resection.
