Complicated right subclavian artery pseudoaneurysm after central venipuncture

Life-threatening complications of central venipuncture are rare. We report an unusual case of a patient in whom a large right subclavian pseudoaneurysm developed, causing pressure necrosis of the membranous trachea and esophagus, after right internal jugular vein cannulation. The patient underwent oversewing of the proximal and distal ends of the subclavian artery and primary tracheal repair. An esophageal leak that presented on the sixth postoperative day was treated by primary suture repair with proximal and distal diversion.
