Central Venous Catheter Misplacement Into Pleural Cavity Causing Hypertensive Pleural Effusion: A Case Report.

Central venous catheter (CVC) insertion is a routine procedure in the management of critically ill patients. We report a clinical case of inadvertent placement of an internal jugular vein CVC into the right pleural cavity, despite employing clinical and imaging-based techniques to ensure proper catheter positioning. Infusion of fluids and vasopressors through this misplaced catheter led to hypertensive pleural effusion and subsequent cardiorespiratory arrest.
