The role of computed tomography angiography as initial imaging tool for acute hemorrhage in the head and neck

Acute hemorrhage in the head and neck (AHNH) is life-threatening due to asphyxiation and hemorrhagic shock. When conservative measures fail, some patients benefit from endovascular therapy (EVT). While CTA is routinely used to localize bleeding and plan EVT in gastrointestinal hemorrhage, the diagnostic value of CTA in AHNH and role of CTA in treatment-planning are uncertain. We retrospectively reviewed neck CTAs from June 2015 to October 2018...
