Abstract

Objectives: To evaluate the blood supply to juvenile nasopharyngeal angiofibroma using digital subtraction angiography (DSA) and its correlation with tumor stages on CT scan. Patients and methods: A descriptive study was conducted on 30 male patients at the Ho Chi Minh City Ear, Nose, and Throat Hospital from July 2019 to July 2024. Results: The tumors were classified according to the UPMC staging system, with stage I accounting for the highest proportion (40%). Eight tumor-feeding arterial branches were identified, with the ipsilateral maxillary artery being the primary blood supplier, providing blood to all cases and serving as the sole blood source in 50% of stage I patients. Additionally, 33.3% of patients had tumors supplied by bilateral arterial systems, and 16.7% of tumors received blood from the internal carotid artery, primarily in stages IV and V. The involvement of the internal carotid artery in advanced stages was statistically significant (p < 0.001). Conclusion: The ipsilateral maxillary artery is the main blood supplier for early-stage tumors, whereas the internal carotid artery plays a significantly more important role as the tumor progresses to advanced stages.
