BackgroundCarotid Blowout (CBO), a neuro-oncological emergency characterized by the rupture of the carotid artery, has been predominantly reported in patients with head and neck cancer who have undergone radiation therapy. In this study, our objective is to share our experience with deconstructive and reconstructive endovascular treatments for CBO.MethodsThis study includes 17 patients who experienced intractable acute CBO, presenting with ear, oral, or nasal bleeding, between 2003 and 2022. We employed deconstructive embolization using vascular plugs, expanding hydrogel coils, glue, and balloons. If vascular anatomy and pathology permitted, we opted for reconstructive treatment using a covered stent. All patients underwent clini-cal follow-up visits, and we used the modified Rankin Scale to evaluate the clinical success of the procedures. We compared outcomes in terms of complications between the deconstructive and reconstructive treatment methods using the Chi-square test.ResultsThe patient cohort had an age range of 20-64 years (mean 50.9), including three females (18%) and 14 males (82%). We conducted 15 endovascular procedures on 14 patients during 19 angiography sessions. All 15 treatments achieved immediate hemo-stasis, resulting in complete technical success (p=1.0). Six patients (35%) underwent reconstructive treatments with covered stents in the internal carotid artery, while nine patients (65%) underwent deconstructive embolization in either the external or internal carotid artery. We found no significant association between the treatment paradigms (deconstructive vs. reconstructive) and the development of complications using a Chi-square test of independence X² (2, n=15)=0.07, p=0.79.ConclusionRecent advancements in endovascular treatments have shown promising results in managing life-threatening acute CBO cases. Our study found no significant difference in outcomes between deconstructive and reconstructive endovascular paradigms in such patients. However, it is important to note that the available data, including ours, is heterogeneous and scarce, necessitating higher levels of evidence to draw more definitive conclusions.
