Abstract
Epistaxis is not uncommon, with up to 60% of the population suffering from at least
one episode in their lifetime and as many as 6% presenting for medical attention.
An analysis of emergency room (ER) visits in the United States between 2009 and 2011
identified 1.2 million encounters for epistaxis, accounting for 0.32% of ER visits.
Approximately 6% of patients will require more aggressive, invasive management in
the form of transnasal ligation of the sphenopalatine artery or endovascular embolization.
This article reviews the epidemiology, rationale for endovascular treatment, strategy
for treatment, endovascular technique, postprocedural follow-up, and complications
and their management.
