Internal maxillary artery pseudoaneurysm in a case of mandibular fracture

Endsocopic internal maxillary artery cauterization in a patient with severe posterior epistaxis: A case report

Epistaxis from the posterior superior region of the nasal cavity might be fatal in some cases. It is particularly severe in an individual with hypertension, arterial aneurysm of traumatic origin, and bleeding from posterior lateral nasal artery, which is frequently difficult to reach and ligate directly on a bleeding area. Certain cases have been reported in which the bleeding could be stopped only by ligating/embolization of the external carotid artery or the internal maxillary artery at its branching off from the external carotid artery. Despite the multiple anastomoses, the effect of such ligation or cauterization is effective if properly done. We present a case of a 25-year-old young man with a 3-month history of recurrent epistaxis resulting from an internal maxillary artery aneurysm following trauma. The clinical presentation, diagnosis, and successful endoscopy treatment of posterior epistaxis are presented.

Non-pulsatile traumatic pseudoaneurysm of the internal maxillary artery following trauma to mandible

Traumatic pseudoaneurysm involving the maxillary artery is rare. Owing to its anatomic location, internal maxillary artery is usually protected by its surrounding structures. Formation of pseudoaneurysm usually takes place after several weeks to months of the initial injury. In this case, we reported a pseudoaneurysm arising from left internal maxillary artery following blunt injuries within 3 hours after a road accident and the treatment with endovascular embolization with titanium coils prior to open reduction and internal fixation of the fractured mandibles.

Endovascular treatment of intractable bleeding from a traumatic pseudoaneurysm of the internal maxillary artery

Traumatic pseudoaneurysms of the internal maxillary artery (IMA) are rare and difficult to treat. A 58-year-old man with a traumatic pseudoaneurysm of the IMA presented with intractable nasal and oral hemorrhage during dual antiplatelet therapy. Transcatheter artery embolization with N-butyl cyanoacrylate (NBCA) completely occluded the pseudoaneurysm. Transcatheter artery embolization with NBCA is a feasible and effective treatment because of its shorter treatment time and lower incidence of recurrence.

Management of pseudoaneurysm of internal maxillary artery resulting from trauma

Pseudoaneurysm of internal maxillary artery following trauma is a rare clinical entity. A rapidly growing swelling in the facial region following fracture of the mandibular subcondylar region is an indication of a developing aneurysm. A case of pseudoaneurysm of the internal maxillary artery following condylar fracture of mandible is reported. The case was treated successfully by surgery.

Sudden rupture of the internal maxillary artery causing pseudoaneurysm (mandibular part) secondary to subcondylar mandible fracture

The mandible is one of the most frequently fractured bones of the face. Condylar fractures are the most common mandibular fractures in adults. The potential complications of mandibular fractures are infection, paresthesia, malunion, nonunion, asymmetry, and long-term functional and growth disturbances. In this article, we report an uncommon case of life-threatening pseudoaneurysm of the internal maxillary artery secondary to subcondylar fracture. We believe that the subcondylar fracture on the vertical vector and oblique direction can damage vital tissues such as the internal maxillary artery, and this injury was, to our knowledge, the first reported acute pseudoaneurysm, which occurred just after the injury at the initial part of the maxillary artery.
