Aug 13, 2024 · Similarly, hypercholesterolemia or hyperlipidemia can also provide sufficient trauma to the vessel wall resulting in dolichoectasia. Jan 10, 2011 · The primary cause of dolichoectasia seems to be aberrant vascular remodeling. One of our VBD patients presented with brainstem infarction initially, received low molecular weight heparin Vertebrobasilar dolichoectasia is a well-described phenomenon thought to be associated with hypertension and resultant vascular wall damage. most commonly affected is the vertebrobasilar artery, see: vertebrobasilar dolichoectasia (VDBE) internal carotid artery (ICA) is also at high risk to be affected. Dolichoectasia of the vertebrobasilar artery is a vascular anomaly characterized by marked elongating, widening, and tortuosity of the arteries.
