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.
