Abstract
Central venous catheter (CVC) placement is a routine but not risk-free procedure, with potential complications including hemothorax. We present a case of a 71-year-old male with coronary artery disease (CAD) who developed intraoperative hemothorax following internal jugular vein CVC placement. The patient experienced profound hypotension during surgery, prompting intervention. Subsequent exploration revealed a small abrasion on the right lung surface caused by an inadvertent initial CVC puncture, leading to hemothorax. The patient was successfully resuscitated, and prompt identification and management of hemothorax were critical. This case emphasizes the importance of vigilance, communication, and early consideration of complications like hemothorax post-CVC placement when unexplained hemodynamic instability occurs. We believe that the use of ultrasonic guidance or fluoroscopic guidance during CVC placement could reduce unusual major mechanical complication rates even during emergencies.
