Recurrent catheter-related right atrial thrombosis in a hemodialysis patient: A case report and literature review.

Right atrial thrombus is an uncommon yet potentially life-threatening complication associated with central venous catheterization. We report an unusual case of catheter-associated right atrial thrombosis (CRAT) in a patient receiving maintenance hemodialysis, who presented with recurrent thrombus on the fifth day following surgical thrombectomy. This report summarizes the clinical presentation, diagnostic modalities, and management strategies for CRAT. Our intention is to improve clinicians' awareness of this complication and provide practical insights into optimal management in hemodialysis patients.
