Survival analysis of a comprehensive treatment strategy for internal carotid artery blowout syndrome by nasopharyngeal carcinoma

Abstract Objective To retrospectively analyze the comprehensive treatment strategy for internal carotid artery blowout syndrome (CBS) by nasopharyngeal carcinoma (NPC). Methods Of the 311 patients of NPC with carotid artery blowout syndrome admitted at our center from April 2018 to August 2022, 288 were enrolled. Results The patients were divided into two groups: treatment group (266 cases) and control group (22 cases). After comprehensive treatment, the survival rate of the treatment group was significantly higher than that of the control group, especially within 6 months to the 1 year. Preventive intervention for CBS I type may have considerable benefits. And in the long run, this treatment strategy did not significantly increase the incidence of stroke in the treatment group. Conclusion The comprehensive treatment strategy for ICA‐CBS of patients with NPC significantly reduced the mortality of asphyxia due to epistaxis, reduced the incidence of CBS during nasal endoscopy, and finally improved survival rate.
