Right internal jugular venous cannulation complicated by tension hydrothorax

Rare complication of central venous catheter placement: bilateral hydrothorax

Central venous catheters (CVCs) are very useful tools in clinical medicine. It is important not only for the administration of medications or fluids but also the measurement of haemodynamic variables, especially in intensive care patients. CVC placement is a relatively safe procedure but may occasionally be associated with complications, such as pneumothorax, haemothorax, cardiac tamponade, sepsis and thrombosis. We aim to report an extraordinary case of bilateral hydrothorax due to CVC placement.

When one port does not return blood: two case reports of rare causes for misplaced central venous catheters

We present two cases of misplaced central venous catheters having in common the absence of free blood return from one lumen immediately after placement. The former is a case of right hydrothorax associated with central venous catheterization with the catheter tip in intra-pleural location. In this case the distal port was never patent. In the latter case there was an increased aspiration pressure through the middle port due to a catheter looping. The absence of free flow on aspiration from one lumen of a central catheter should not be undervalued. In these circumstances the catheter should not be used and needs to be removed.
