Vascular access is a crucial prerequisite for successful hemodialysis treatment. An in-sertion of tunnelled central venous catheter is one option to create vascular access.
Central vein stenosis is a frequent problem in dialyzed patients, especially after previous can-nulation. External compressions caused by malignant or non-malignant diseases are less frequent.
Achalasia as a cause, complicating the insertion of a tunnelled dialysis catheter, is a rarity.
