Misplacement of pulmonary arterial catheter in the inferior vena cava: a case report

A 60-year-old male patient underwent liver transplantation surgery due to autoimmune cirrhosis and hepatocellular carcinoma. Placing a pulmonary arterial catheter (PAC) for hemodynamic monitoring was challenging despite using ultrasound and multiple adjustments. The PAC anomalously lodged in the inferior vena cava despite corrective attempts, influencing the surgical approach. To avoid possible complications, it was decided to remove the PAC. No subsequent complications related to PAC misplacement were observed, and the patient recovered post-surgery without incident. This case underscores the importance of following the precision in PAC insertion procedures, such as waveform analysis.
