A case series of preoperative endovascular embolization of nasopharyngeal angiofibroma.

Nasopharyngeal angiofibroma (NA) is a relatively rare, noncancerous, extremely vascular tumor, and it is only found in males. NA receives blood supply from various sources and can lead to major blood loss after surgical excision. Nowadays, endovascular embolization has the potential to reduce intraoperative bleeding and lower the recurrence rate. This case series aimed to describe the preoperative endovascular embolization of nasopharyngeal angiofibroma. In this study, we reported 3 cases of adolescents with NA diagnosed using CT angiography. All subjects had a successful embolization, which led to minimal postoperative bleeding and good outcome.
