Ruptured superior thyroid artery from central vein cannulation: treatment by coil embolization.

Abstract

Central vein cannulation is associated with several complications, some of which may be fatal. This case report describes a life-threatening complication after insertion of a central venous line. An obese female patient with end-stage renal failure due to nephrotic syndrome developed a huge neck swelling and sudden airway obstruction after attempted cannulation of the internal jugular vein for haemodialysis. Tracheal intubation was achieved using a gum-elastic bougie. Investigations revealed abnormal blood clotting. The coagulopathy was treated, but the neck swelling continued to increase in size. Carotid angiography showed a ruptured right superior thyroid artery. The haemorrhage was controlled by coil embolization of the artery. This case report demonstrates the usefulness of the gum-elastic bougie in the presence of a difficult airway and of interventional radiology in the management of vascular accidents.
