Traumatic Buccal and Inferior Alveolar Pseudoaneurysm Associated With Von Willebrand Disease: A Challenging Case Treated by Endovascular Approach.

Pseudoaneurysm resulting from the external carotid artery or its branches after trauma to the maxillofacial region is unlikely, even more so, in a patient with von Willebrand disease. This study aimed to report a challenging case of pseudoaneurysm of the buccal artery and inferior alveolar artery due to a mandible fracture in a traumatized patient with undiagnosed von Willebrand disease. This reported case was conducted by a multidisciplinary team, covering the departments of maxillofacial surgery, interventional neuroradiology, neurosurgery, and hematology. From a fracture of the lower jaw and the appropriate course of action, bleeding episodes followed until intervention with embolization therapy. To our knowledge, this is the first case reported in the literature of a patient with those conditions.
