Intrapericardial Dialysis Catheter: A Rare Cause of Cardiac Tamponade Emphasizing the Importance of Early Diagnosis and Management

We report a rare and serious case of intrapericardial malposition of a dialysis catheter in a 70-year-old patient with chronic kidney disease secondary to IgG kappa amyloidosis. The complication was initially revealed by an episode of supraventricular arrhythmia and confirmed through imaging studies. Catheter removal led to hemodynamic decompensation due to a compressive pericardial effusion, which required emergency sternotomy for drainage. The postoperative course was favorable. This case highlights the importance of thorough assessment of catheter placement and the need for prompt, multidisciplinary management in rare but potentially fatal complications of hemodialysis.
