Jan 10, 2011 · The primary cause of dolichoectasia seems to be aberrant vascular remodeling. It most commonly occurs in posterior circulation (vertebrobasilar dolichoectasia), followed by supraclinoid internal cerebral artery. Trigeminal neuralgia (TN) is chronic neuropathic pain. This well-established vascular anomaly has been associated with subsequent strokes, microembolization, brainstem, and cranial nerve compression ( 3 We would like to show you a description here but the site won’t allow us. 1% for stroke patients [], reliable population-based data are lacking.
