Carotid blowout syndrome: endovascular management of a lesser known oncological emergency: case report

Background Carotid blowout syndrome (CBS) refers to a fatal hemorrhagic complication of cervical carotid arteries that occurs due to rupture of the extracranial carotid artery or one of its major branches in patients treated for head and neck malignancy. In this article, we will discuss two different spectrum of CBS and endovascular approach. Case presentation Two cases of per oral bleeding presented in the emergency department. After patients were hemodynamically stabilized, CT angiography was done which showed type II CBS and type III CBS, respectively. This was followed by transfemoral supra-aortic digital subtraction angiogram coil embolization with scaffolding and anchoring technique, respectively, for the patients. Conclusions Early recognition of the predictors of CBS by a multidisciplinary team is critical. The endovascular treatment approach is relatively safe and effective with low rates of morbidity and mortality compared to surgical approach in CBS.
