This case highlights the need for clinical suspicion of carotid artery injury in patients with neck pain following low-energy trauma, even without a significant decrease in consciousness.
Carotid injury may occur after mild trauma; extends spectrum but leaves screening and management open.
Dear Editor, In severe trauma, in 1% to 3% of the patients can be verified vascular injuries in neck vessels.[1] Recent studies have described a higher prevalence of blunt cervical vascular injury.[23] Death associated with internal carotid pseudoaneurysm is 20% to 30% of the cases.[4] Most of these injuries are associated with high-energy trauma in motor vehicle accidents.[3] However, carotid artery dissection and pseudoaneurysm in mild trauma is a very rare disease. A 27-year-old female patient, admitted after a car accident, with bruise in the neck and 14 points in the Glasgow Coma Scale (GCS) with normal skull computed tomography. She remained with significant neck pain, and then, we performed cervical angiotomography [Figure 1] that revealed an internal carotid artery (ICA) pseudoaneurysm. An angiography [Figure 2] confirmed pseudoaneurysm and dissection. The patient was treated with carotid stenting, uneventful. She was discharged with 15 points in the GCS, without motor deficits.Figure 1: Computed tomography angiography showed pseudoaneurysm in the right internal carotid arteryFigure 2: Digital angiography image. In (a) preoperative image showing pseudoaneurysm and dissection in internal carotid aneurysm and (b) postoperative image showing improve of dissection segment with stentTraumatic lesions of the ICA may occur associated with only cervical pain[56] as in our patient. However, this is a special case because involves low-energy trauma. A great number of dissections can be treated with medical therapy and <10% progress to a pseudoaneurysm. In vascular injuries like in our patient, the endovascular intervention is indicate to occlude the pseudoaneurysm to decrease the risk of future hemorrhages and neurological deficits.[3] The important point that we observed with this rare clinical case is that clinical suspicion is necessary for carotid artery injury, even in traumas without decrease of the level of consciousness.

Paiva et al. (2018) conducted a case report in Mild traumatic brain injury with internal carotid artery dissection and pseudoaneurysm (n=1). Carotid stenting was evaluated on Neurological outcome at discharge. A 27-year-old female with mild traumatic brain injury and internal carotid artery dissection with pseudoaneurysm was successfully treated with carotid stenting and discharged without motor deficits.
