Posttraumatic Lingual Artery Pseudoaneurysm Treated with Ultrasound-Guided Percutaneous Thrombin Injection

Posttraumatic Lingual Artery Pseudoaneurysm and Synchronous Multiple Pneumatosis in a Child

“…The most common cause of pseudoaneurysm is iatrogenic, whereas other causes include trauma, radiation therapy, and infection . Usually pseudoaneurysms are formed within hours, but cases reporting pseudoaneurysms as late as 8 months after the precipitating event have been published . Treatment options include endovascular embolization, artery ligation, and ultrasound-guided percutaneous thrombin injection .…”

“…A pseudoaneurysm occurs when the wall of an abnormally dilated blood vessel is replaced by fibrous tissue, in contrast to a true aneurysm, where all 3 layers remain intact . The repair of pseudoaneurysms is necessary owing to the possibility of rupture and massive hemorrhage.…”

“…Posttraumatic pseudoaneurysms of the lingual artery are extremely rare. To our knowledge, only 7 cases have been reported in the literature, all concerning adult patients, after high-energy or penetrating neck trauma …”

Pseudoaneurysm of the lingual artery as an unusual radiological finding of oropharyngeal carcinoma

“…The patient described was not deemed for further treatment, nevertheless there is a less invasive alternative to transarterial embolization, the US-guided percutaneous thrombin injection, 12,13 although expert management is required and distal embolization can occur.…”

Craniofacial Trauma and Vascular Injury

“…Treatments involve endovascular embolization or thrombin injection, though surgical approaches are also available. [65][66][67] Patients with skull fractures involving the MMA groove can result in vascular lesions including active contrast extravasation (71%) and pseudoaneurysm (29%) on angiography 68 and are associated with a high mortality rate. 69 The MMA branches off the maxillary artery in the infratemporal fossa and courses through the foramen spinosum into the middle cranial fossa.…”
