BILATERAL ABSENCE OF POSTERIOR COMMUNICATING ARTERIES – a case report

Dr. Hemamalini, Kiran Kumar D, Dr. Saraswathi G

Abstract :

 The major arterial supply to the ain is by an arterial circle – circle of Willis situated in the interpeduncular cistern of the ain. It is formed by the anastomosis of the anches arising from the internal carotid and verteal arteries. Posterior communicating artery is the main anastomotic channel between the carotid and verteobasilar circulation. During routine dissection of ain for undergraduate students in a 70years old male cadaver, we observed bilateral absence of posterior communicating arteries. Right verteal artery was smaller than the left. Individuals with absence of posterior communicating artery/verteal artery hypoplasia are more prone to develop stroke, migraine and cognitive dysfunction. Knowledge of variation in the posterior communicating arteries is not only important to diagnose neurological disorders but also important from surgical and angiographic point of view.
