OBJECTIVE: The management of traumatic pseudoaneurysm (PA) with concomitant arteriovenous fistula (AVF) arising from the thyrocervical trunk is challenging and rarely reported. Here, the usefulness of a multi-modal endovascular strategy for management of traumatic PA and AVF arising from the thyrocervical trunk is presented. A literature review describing unique clinical features and management strategies of traumatic vascular lesions of the thyrocervical trunk is included.

METHODS: A 58-year-old man presented with two PAs arising from the ascending cervical artery (AsCA) and a robust AVF between the AsCA and the left vertebral venous plexus which arose acutely after a stabbing incident. These lesions were managed with endovascular vessel sacrifice via coiling and controlled Onyx injection. Relevant literature was identified via a targeted search of the PubMed database.

RESULTS: Post-management angiography demonstrated complete occlusion of the two traumatic PAs and successful disconnection of the concomitant AVF. Our literature review demonstrates a shift in preferred management approach from invasive surgery to endovascular treatment due to the lower risk and cosmetic preferability.

CONCLUSION: Timely treatment of enlarging PA is necessary for reducing associated morbidity and mortality. While surgical resection has been the mainstay therapy, endovascular management has gained popularity in recent years. The choice of endovascular technique is variable and should be individualized based on patient's clinical status, associated risk factors, and lesion morphology. We have shown that parent vessel sacrifice is safe and effective. Reconstruction with a combination of stents, coils, glue, or liquid embolics may be necessary when collateral flow is limited.
