Pseudoaneurysm following “routine” third molar extraction: a case report and review of the literature

An Unusual Presentation of a Neck Mass – Traumatic Pseudoaneurysm Following Third Molar Surgery: A Case Report

“…13 TPA related to dental extractions have been reported to occur at the lingual artery, internal maxillary artery, facial artery, and inferior alveolar artery. 3,[6][7][8][9][10]14,15 When there is clinical concern for the occurrence of a TPA, a CTA remains the preferred diagnostic modality for initial evaluation. 11 However, when a CTA cannot be obtained, the utilization of ultrasonography and color Doppler can also verify a pseudoaneurysm with the visualization of bidirectional blood flow as shown in this case.…”

“…Third molar surgery, also known as wisdom tooth extraction, is one of the most common procedures performed by the oral and maxillofacial surgeon with a generally low complication rate. [1][2][3] Adverse events most often include infection, alveolar osteitis, bleeding, or swelling. 3 Less common complications include paresthesia, mandibular fracture and displacement of teeth or instruments.…”

“…[1][2][3] Adverse events most often include infection, alveolar osteitis, bleeding, or swelling. 3 Less common complications include paresthesia, mandibular fracture and displacement of teeth or instruments. Traumatic pseudoaneurysm (TPA) formation is an extremely rare complication which has been reported in the literature as a potential sequela following tooth extraction.…”

“…Traumatic pseudoaneurysm (TPA) formation is an extremely rare complication which has been reported in the literature as a potential sequela following tooth extraction. [3][4][5][6][7][8][9][10][11] In the maxillofacial region, TPA is most often associated with penetrating trauma, condylar fractures, and orthognathic surgery and involves the branches of the internal maxillary artery. 3,4 TPA occurs when there is disruption in the vascular endothelium followed by blood extravasation into the adventitia or adjacent soft tissue.…”

The resulting collection of blood may continue to expand, leading superimposed infection, severe hemorrhage, or thromboembolism.…”
