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. Return of spontaneous circulation was achieved after two cycles of cardiopulmonary resuscitation. While multiple imaging modalities are recommended for confirming appropriate CVC placement, each method has inherent limitations. This case highlights the imperative need for a high index of suspicion to avert such complications and pretends to review some of each method's limitations.
