Post-traumatic pseudoaneurysm of the common carotid artery associated with arteriovenous fistula to the internal jugular vein: A case report.

Traumatic arteriovenous fistulas (AVFs) occur in up to 30 % of cases involving the cervical region, with the concomitant presence of AVF and pseudoaneurysm being a rare but clinically significant condition. This case report describes a 32-year-old male victim of a stab wound in Zone II of the right cervical region, who presented with a palpable thrill and subcutaneous emphysema. Cervical computed tomography angiography (CTA) revealed a pseudoaneurysm of the right common carotid artery and an AVF with the right internal jugular vein. The patient underwent successful endovascular repair using a covered stent, achieving complete resolution of the condition without any neurological or functional deficits. This case underscores the rarity of traumatic AVFs associated with pseudoaneurysms and emphasizes the importance of a systematic evaluation in penetrating cervical trauma. Additionally, it shows CTA as a crucial non-invasive diagnostic tool and demonstrates the effectiveness of endovascular treatment as a safe, minimally invasive, and highly efficient alternative to conventional surgical approaches.
