Abstract

Pseudoaneurysms are rare complications of orgthognathic surgery, trauma or other surgical procedures in the head and neck regions. Surgical approach is a routine procedure of bleeding control. However, bleeding control using angiography and embolization can also be an excellent method. We experienced pseudoaneurysm of the inferior alveolar artery occurring after surgical curettage of cystic lesion. The 33-year-old man who underwent surgical curettage of keratocystic odontogenic tumor was presented with severe bleeding in the right mandible ramal inner surface 14 days after the surgical curettage. After hemostasis with vaseline gauze packing and pressure, bleeding temporarily stopped. However, bleeding started after 14 days and soon it has been continued. Finally, the patient was diagnosed as pseudoaneurysm of the inferior alveolar artery from the enhanced-computed tomography images, and angiographic embolization was performed successfully. We report a rare case of pseudoaneurysm of the inferior alveolar artery after benign tumor curettage and review of the previewer's literature.
