title: [Epistaxis: emergency treatment approach].
abstract: After a brief summary of the causes of severe epistaxis and the surgical choices available for treatment, the authors present their own cases study. Starting from a brief description of the anatomy involved in the system of arterial irrigation of the nasal cavities, they focus on two fundamental concepts: the basis for a proper topographic picture of the site of bleeding and the success of surgery. First and foremost is the emergence of two arterial branches from the sphenopalatine formen; this differs from what is asserted in the classical treatise on anatomy and in line with what has been stated in the Nomina Anatomica, approved during the X World Congress on Anatomy (Tokyo 1975). Secondly, focus is placed on the existence of two important anastomotic systems in the arterial circulation of the nasal cavities: the one between nasal septum and anterior-posterior ethmoid arteries and the one between the lateral-posterior nasal and nasoseptal arteries. In the literature the failure of surgery in treating severe epistaxis is explained by the onset of supplementary anastomotic circulation. The indications for surgical treatment of epixstaxes are: copious bleeding in hospital or after the packing has been removed; underlying pathology or general status which has been aggravated by the packing; patient which has already been staunched several times. The results of 31 epistaxis procedures are presented: 8 (25.81%) upper and 23 (74.19%) posterior. The upper epistaxes were treated as follows: 3 cases with anterior ethmoid ligature, two of which failed; 2 cases with combined ligature of the anterior and posterior ethmoid; 3 cases of successful septoplasty. The posterior epistaxes were treated as follows: 11 cases of ligature of the lateral-posterior nasal artery, 2 of which failed; 12 cases of successful combined ligature of lateral-posterior nasal and nasoseptal arteries. These results confirm that it is possible to effectively resolve surgically severe epistaxis using microsurgery or transnasal endoscopy based on in depth knowledge of the complex architecture of the arterial circulation within the district of the paranasal sinuses, possible anatomic variations and collateral circulation.
