Transverse cervical artery pseudoaneurysm: a rare complication of internal jugular vein cannulation

Internal jugular vein cannulation has become the preferred approach for temporary hemodialysis catheter placement following reports of an increased incidence of subclavian vein stenosis due to subclavian vein catheterization. Internal jugular vein catheterization is associated with a high rate of successful catheter placement. However, significant complications such as internal carotid artery (ICA) puncture, pneumothorax, vessel erosion, thrombosis, airway obstruction and infection can occur. The most common complication is ICA puncture. More recently a few cases of thyrocervical trunk pseudoaneurysm and fistula following internal jugular vein and subclavian vein catheterization attempts have been reported. Patients with renal failure who are on hemodialysis may have to undergo multiple catheter placements and vascular access interventions. This, along with their comorbid conditions, increases the risk of such complications. Here we report a patient on hemodialysis who developed transverse cervical artery pseudoaneurysm following an attempted right internal jugular vein catheterization. We report this case because of its rarity, to raise awareness of such a complication and to discuss different treatment options, in particular endovascular coil occlusion. A review of relevant literature is also presented.
