[Pharyngeal hemorrhaging due to iatrogenic false aneurysm. Complication after cannulation of the internal jugular vein].

Catheterization of the internal jugular vein is used for temporary access to the central vein in patients with acute or chronic renal failure. The most frequent problem is the arterial puncture and accidental placement of the large catheter in an artery. This case report describes a rare secondary complication by accidental catheterization of the right common carotid artery after intended dual lumen catheter insertion into the right internal jugular vein. A false aneurysm with pharyngeal hemorrhaging developed 2 weeks after the puncture. The diagnosis was made using colour-Doppler ultrasound and the aneurysm was treated with vascular surgery.
