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

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.
