- W4293442022 abstract "<h3>Introduction</h3> Bleeding in patients with head-neck cancers could be from a carotid blow out or external -carotid artery (ECA) source. Management of latter is a poorly discussed subject. <h3>Objective</h3> To review the effectiveness and safety of embolization in managing ECA territory hemorrhage in head-neck cancer patients. <h3>Methods</h3> We retrospectively reviewed head -neck cancer patients who presented with severe oronasal bleeding and underwent digital-subtraction-angiography between June-2011 to June-2021. Internal-carotid artery blowouts were excluded and those who underwent embolization of the ECA territory branches were included in the study. The outcomes of embolization were reviewed. <h3>Results</h3> Fourteen patients with 15 embolizations were identified. Technical success rate of embolization was 100% with no procedural complications. Overall long-term hemostatic rate was 53.3% (8/15). The re-bleed rate of targeted and empiric embolizations was 42.9% (3/7) and 50.0% (4/8) respectively. There was no rebleed in any of the 5 patients where liquid embolics were used. The median time to rebleed was 5 days (IQR 4–53 days). Five of the 6 patients with rebleed underwent surgical ligation of sphenopalatine or ECA. A third intervention was required in 3 of these patients. In one patient who went for re-embolization, the source of bleeding was different from before. <h3>Conclusion</h3> Technical success rate and safety of embolization for head- neck cancer reated ECA territory bleeds is excellent; but re-bleeding is common. The role of liquid embolics in reduce rebleeding need further evaluation. Rebleeds is high with surgical hemostasis as-well. Hence the managing clinicians and patients should be prepared for re-interventions. <h3>References</h3> Bachar G, Esmat N, Stern S, <i>et al</i>.
