Manejo de pseudoaneurisma de la arteria esfenopalatina posterior a osteotomía LeFort I

The formation of pseudo-aneurysms in the vascular complex of the maxillofacial region are not common, reports found in the literature indicate that blunt mechanisms (iatrogenesis) is the main cause. We describe the case of a 17-year-old male patient with dentofacial disharmony, who presented a pseudo-aneurysm of the right sphenopalatine artery, as a rare and serious complication to a Lefort I osteotomy, which was treated with trans-arterial embolization by means of the release of two coils. We reviewed the concepts of aneurysms as well as the modalities for their treatment. Suggesting endovascular intervention as the first line of management, relegating surgical intervention to situations of penetrating trauma, with adequate facilities and skills.
