Pneumothorax is one of the most frequent complications during percutaneous central vascular cannulation. When choosing a site for central vascular access, the internal jugular vein is preferable to other vessels, for the lower frequency of related complications, including pneumothorax. This review intends to summarize the current state of the art on how to avoid and, if it occurs, to manage this rare but relevant complication. ⋯ To exclude the presence of asymptomatic pneumothorax, in the normal clinical routine a chest X-ray should be obtained within 4 hours from the procedure of central vein cannulation of subclavian and internal jugular veins. If promptly recognized, pneumothorax can be managed quickly and in a relatively easy way. Depending on its size and symptoms, and in particular when a tension pneumothorax is suspected, treatment can vary from simple observation to a chest tube insertion or, in the latter case, to an emergency thoracentesis needle insertion in the pleural space.

Cannulation of central veins and placement of catheters for temporary haemodialysis is a common procedure in the management of patients with end stage renal failure. The internal jugular vein is the site of choice for central venous catheter placement, being associated with the lowest complication rate. ⋯ For anatomical reasons, the risk of azygos arch cannulation is substantially increased if catheters are inserted via left-sided veins. We report a case with a rare complication associated with the insertion of a catheter for temporary haemodialysis.
