RESUMEN
Embolisation of head and neck hypervascular tumours and arterioveinous malformations [AVMs] is now a well-established therapeutic procedure. The purpose of this study was to analyse the technique and to evaluate the safety and value of preoperative embolization of hypervascular lesions. We retrospectively reviewed the records of 5 patients, aged between 14 and 47 years, with hypervascular tumours and AVMs in the head and neck. Lesions were distributed as follow: nasal angiofibroma [n=1], nasal angioleiomyoma [n=1], nasopharyngeal angiofibroma [n=1], aneurysmal bone cyst in the posterior element of the second cervical vertebra [n=1] and AVM of the inferior lip [n=1]. Angiography and embolization were carried out at the same time. Complete exclusion of lesions was obtained without any complications. Complementary surgical resection was performed with not notable blood loss
