Cerebral infarct secondary to traumatic internal carotid artery dissection.

Background: Traumatic internal carotid artery dissection (TICAD) is rare and can result in severe neurological disability and even death. No consensus regarding its diagnostic screening and management has been established.

Aim: To investigate the clinical presentation, imaging features, diagnostic workup, and treatment of TICAD.

Methods: In this retrospective case series, emergency admissions for TICAD due to closed head injury were analyzed. The demographic, clinical, and radiographic data were retrieved from patient charts and the picture archiving and communication system.

Results: Six patients (five males and one female, age range of 43-62 years, mean age of 52.67 years) presented with TICAD. Traffic accidents (4/6) were the most frequent cause of TICAD. The clinical presentation was always related to brain hypoperfusion. Imaging examination revealed dissection of the affected artery and corresponding brain infarction. All the patients were definitively diagnosed with TICAD. One patient was treated conservatively, one patient underwent anticoagulant therapy, two patients were given both antiplatelet and anticoagulant drugs, and two patients underwent decompressive craniectomy. One patient fully recovered, while three patients were disabled at follow-up. Two patients died of refractory brain infarction.

Conclusion: TICAD can cause catastrophic outcomes and even refractory brain hernia. Early and efficient diagnosis of TICAD is essential for initiating appropriate treatment. The treatment of TICAD is challenging and variable and is based on clinician discretion on a case-by-case basis.
