Case series of pre-operative endovascular embolization of nasopharyngeal angiofibroma using polyvinyl alcohol foam particle: A single centre experience

Abstract

BACKGROUND: Nasopharyngeal Angiofibroma is a rare neoplasm in the sphenopalatine foramen. This tumour is histologically benign, but clinically malignant because it can erode the bone and surrounding structures, such as the pterygopalatine fossa, paranasal sinuses, and nasal cavity. It is a highly vascular tumour, sometimes from multiple Feeding arteries, and tends to bleed easily. CASE PRESENTATION: In these cases, series, we reported four cases of nasopharyngeal angiofibroma in children and one case in an elderly patient. The diagnosis was made by history taking, physical examination and Cerebral MSCT Angiography, as well as Digital Subtraction Angiography (DSA). After identification of the Feeding artery, we performed transarterial embolisation using polyvinyl alcohol (PVA) foam particles. CONCLUSION: Preoperative embolisation in the highly vascular tumour, such as nasopharyngeal angiofibroma, is very useful to reduce peri-operative complication of surgery. This procedure can reduce blood loss during resection of the tumour and gives better outcomes.
