Which of the following aery is NOT ligated in a case of epistaxis?
High-Yield Explanation
Internal carotid aery shouldn't be ligated in epistaxis due to risk of development of collateral blood flow into pseudoaneurysm leading to recurrent epistaxis. Aeries which can be ligated in a case of epistaxis are: Anterior and posterior ethmoidal aery, sphenopalatine aery (SPA). More rarely the internal maxillary aery or the External Carotid Aery can be ligated.
