In simple words: The doctor uses a tiny balloon or other tools to clear a blockage inside a central line (a tube used for giving medicine or fluids directly into a large vein). This helps the medicine or fluids flow properly again.

The physician inserts a wire, balloon catheter, or other instruments through the outer opening and into the lumen (interior channel) of a central venous device and pushes or pulls out the obstructive material. This procedure facilitates normal flow within the catheter lumen.

Example 1: A patient with a PICC line experiences difficulty with infusions due to a blockage. The physician uses a balloon catheter to remove the obstruction, restoring normal flow., A patient's central venous catheter is occluded by a fibrin sheath. The physician mechanically removes the sheath, allowing for continued use of the catheter., A patient with a port-a-cath experiences difficulty flushing the device.A physician uses a wire to remove an intraluminal obstruction, restoring patency.

Documentation should include the type of central venous access device, the method used to remove the obstruction, and the result of the procedure.If imaging guidance is used, that should also be documented.
