A Case Report of Arteriovenous Fistula Penetrating into the Ascending Aorta Due to Right Internal Jugular Vein Placement.

Internal jugular vein placement is frequently utilized in clinical practice for rapid infusion, intraoperative monitoring, peritoneal dialysis, and access for interventions. Additionally, the process may lead to complications like hematoma, infection, misdirection of the artery, pneumothorax, and arteriovenous fistula. In the case described in this report, all vascular ruptures effectively were repaired because when internal jugular vein placement was adopted, a dialysis catheter would go through the right internal jugular vein into the subclavian artery, then the ascending aorta via the cephalic trunk, and finally the ectopic catheter would be surgically removed. The patient was released from the hospital on the seventh postoperative day after maintaining stable vital signs throughout the procedure.
