Retrospective evaluation of pericardial catheter placement in the management of pericardial effusion in dogs (2007-2015):18 cases.

Thoracic drainage catheters inserted into the pericardial space via a modified-Seldinger technique can be positioned in dogs to aid management of PEs. The main associated adverse event is arrhythmia. Minimal sedation is required for placement, and dogs tend not to require postprocedural analgesia. Catheters can remain in situ for repeated drainage, potentially decreasing staffing time requirement and repeat sedation. Their use is associated with a rate of arrhythmia requiring treatment of 22%, compared to that of needle pericardiocentesis alone at 13%. They are easy to position using equipment available in many facilities.
