Case Reports[Intracranial post-traumatic aneurysm of the internal carotid artery as cause of epistaxis: considerations on 2 cases].
Aneurysm of the internal carotid artery is rarely mentioned as a cause of epistaxis. This condition is quite rare but it is important to consider aneurysms in the etiology of epistaxis because of their high mortality rate and since they require management quite different from that of epistaxis of other origins. After arteriosclerosis the most frequent cause of an aneurysm of the internal carotid artery is a closed or penetrating craniofacial trauma injuring the artery. ⋯ Therefore angiography was performed which revealed a small aneurysm of the intracavernous segment of the left internal carotid artery. Subsequently, an endovascular balloon embolization of the aneurysm was successful, preserving the parent artery. The importance of considering aneurysms in the differential diagnosis of massive epistaxis is emphasized.

Review[Etiopathogenesis and biodynamics of closed laryngo-tracheal injuries].
The blunt laryngotracheal trauma, once quite a rare phenomenon, has become quite relevant today, particularly because of the great increase in automotive traffic. It was, therefore, felt knowledge of the etiopathogenesis and biodynamics of this form of trauma is important for proper diagnosis and treatment. After having noted that the literature in this regard is generally incomplete and fragmentary, the authors felt it worth compiling the various etiopathogenesis and biodynamic factors involved; characteristics of blunt laryngotracheal trauma. ⋯ In 85% of the cases cricoid cartilage involvement is associated with that of the tracheal cartilage. The authors assert that, due to a question of resistance, cricoid fracture traumas almost always involve the trachea while thyroid cartilage fractures act as a relief, letting off and absorbing the forces, thus preventing cricoid involvement. On the basis of these considerations the authors feel it fitting to classify the blunt laryngotracheal traumas into three groups according to topography: supraglottic laryngeal trauma with or without involvement of the glottis; subglottic laryngeal trauma, generally associated with the trachea and only rarely involving the glottic region; isolated trauma of the cervical trachea.
