Successful Endovascular Management of Inferior Thyroid Artery Pseudoaneurysm after Unsuccessful Internal Jugular Vein Catheterisation: A Rare Case Report

Central Venous Catheters (CVCs) are essential for maintaining venous access; however, they are associated with complications such as arterial injury. The present case report details a rare complication of an inferior thyroid artery pseudoaneurysm in a 25-year-old female with lupus nephritis, which occurred following multiple failed attempts at Internal Jugular Vein (IJV) catheterisation. Despite immediate compression, the patient developed tender neck swelling and imaging confirmed the presence of an inferior thyroid artery pseudoaneurysm. Endovascular coil embolisation was performed successfully, with no intraoperative complications. The present case highlights the importance of prompt diagnosis and intervention in managing arterial injuries during CVC placement.
