Learning objectives To understand the importance of identifying and diagnosing various forms of arterial injuries of the head and neck following trauma.
Read more Background Trauma of the head and neck has potential to cause devastating injury to the vasculature responsible for supplying blood flow to the head and neck, most importantly the brain.It is made up of common carotid arteries and vertebral arteries in the neck. The common carotid bifurcates at C4 to become the internal and external carotid arteries. The external supplies structures in the neck and face while the internal continues into the skull.Branches of the external carotid artery include: superior thyroid artery ascending...
Read more Findings and procedure details Arterial injuries in the head and neck can present immediately or can remain indolent for some time. The two major mechanisms of arterial injury are blunt and penetrating trauma. Both may cause: extravasation thrombosis/occlusion pseudoaneurysm formation [fig 1] dissection intramural haematoma arterial transection Vertebral injuries most commonly lead to arterial occlusion whereas penetrating trauma more often causes arterial transections. Later, arteriovenous fistula formation may be seen.Investigation with multislice computed tomography (CT) angiography is preferred due to speed of acquisition and high spatial resolution. This provides superior sensitivity in the...
Read more Conclusion Arterial injuries of the head and neck may have dramatic consequences for patients, necessitating radiologists to be familiar with imaging these traumatic injuries. The Biffl scale offers simple and effective method of communicating results rapidly and accurately for interventions.
