A rare complication of internal jugular vein cannulation: Pseudoaneurysm of the thyrocervical trunk

Central venous cannulations,especially through internal jugular and subclavian veins,are commonly used for different reasons and associated with a high rate of successful placement. however,more than 15% of the patients may have complications. although it is rare,thyrocervical trunk pseudoaneurysm may be one of the complications that follows multiple catheterization attempts. in this report,we present a case of thyrocervical trunk pseudoaneurysm developed after a diffcult internal jugular vein cannulation using a landmark-guided technique. our aim is to emphasize this rare complication,the importance of using ultrasound-guided central venous cannulations,identifying pseudoaneurysm(s) and also the treatment with endovascular coil embolization.
