Traumatic Pseudoaneurysm: A Life-Threatening Complication After Surgical Extraction of Impacted Maxillary Third Molar
- 40 Downloads
Pseudoaneurysms are rare lesions secondary to blunt or penetrating trauma, temporomandibular joint surgery, or orthognathic surgery. They are usually produced by arterial breach leading to extravasation of blood. The compressed perivascular tissue forms the wall of aneurysmal sac. This sac gradually expands and can be damaged. Nonsurgical interventions are the treatment of choice for pseudoaneurysms. In the case reported here, emergent endovascular injection of acrylic glue was successful in the treatment of a pseudoaneurysm from a branch of the internal maxillary artery secondary to surgical extraction of impacted maxillary third molar.
