Treatment of Pseudoaneurysm of Internal Maxillary Artery: A Case Report

“…This rare lesion receives its name from the fact that its vascular wall is composed of fibrous connective tissue (pseudocapsule) that develops after rupture of the endothelium. [1][2][3] Blood leaks into the tissues through a hole during systole and is contained only by muscle fascia. Leaking continues until the hematoma applies enough pressure to counterbalance arterial pressure and control hemorrhage in the affected area.…”

“…Leaking continues until the hematoma applies enough pressure to counterbalance arterial pressure and control hemorrhage in the affected area. [1][2][3] This pulsating liquefied hematoma develops for 1 to 8 weeks and forms a new vascular wall (pseudocapsule) that may rupture and trigger severe hemorrhage or thromboembolism. [1][2][3] Pseudoaneurysms are usually secondary to blunt or penetrating trauma, temporomandibular joint surgery, or orthognathic surgery.…”

“…[1][2][3] Pseudoaneurysms are usually secondary to blunt or penetrating trauma, temporomandibular joint surgery, or orthognathic surgery. [2][3][4][5] The main signs and symptoms are asymmetries, neurological deficits, and thromboembolism. 6 Arteriography is the standard procedure to identify pseudoaneurysms in the maxillofacial region.…”

“…Other imaging studies, such as ultrasound, CT, and magnetic resonance, may also be used. [1][2][3] Nonsurgical interventions are the choice of treatment for this lesion because the large contralateral vascular network makes it difficult to achieve adequate hemostasis when surgical ligation is used. 2 This report describes the treatment of a pseudoaneurysm in the left maxillary sinus secondary to facial trauma.…”
