RESUMEN
Objective:To summarize and analyze the effect of extracranial/intracranial vascular bypass in the treatment of internal carotid artery burst hemorrhage after radiotherapy for nasopharyngeal carcinomaï¼NPCï¼. Methods:A retrospective analysis of the data of 9 patients with nasopharyngeal carcinoma and carotid artery blowout syndromeï¼CBSï¼ who underwent extracranial/intracranial vascular bypass. Collected patient demographics, treatment course and dose of radiotherapy, analyze the effect of extracranial/intracranial vascular bypass on the prognosis of patients with internal carotid artery burst hemorrhage, including perioperative stroke and death, overall survival rate, and rebleeding rate. Results:Nine patients were included in the study. The average age is 53.5 years. The pathological types were all non-keratinizing squamous cell carcinoma, undifferentiated, stage â £; 7 cases of local NPC recurrence, 2 cases of skull base osteonecrosis; all 9 cases had internal carotid artery hemorrhage, including 7 cases of petrous carotid artery and 2 cases of cervical carotid artery; 3 cases of typeâ threatened CBSï¼33.3%ï¼, 2 cases of type â ¡ impending CBSï¼22.2%ï¼, and 4 cases of type â ¢ acute CBSï¼44.45%ï¼. All patients underwent extracranial/intracranial vascular bypass surgery, and there were no perioperative deaths and strokes. The mean follow-up was 16.7 months. The median overall survival time of the patients was 22.1 months and the 90-day, 1-year and 2-year survival rates were 100.0%, 75.0% and 30.0%, respectively. Conclusion:Patients with internal carotid artery burst hemorrhage after radiotherapy for nasopharyngeal carcinoma can be safely treated by extracranial/intracranial vascular bypass surgery and obtain a longer survival rate.
