Surgical management of a hemodialysis catheter-induced right atrial thrombus

The placement of hemodialysis catheters are widely performed by vascular surgeons and surgical residents for use in both the hospital and the outpatient setting. Although long-term complications of this type of vascular access are relatively uncommon, an appreciation is warranted for the life-threatening complication of right atrial thrombus (RAT). Once recognized, medical or surgical management is mandatory to prevent further consequences from RAT. The optimal treatment for catheter-induced RAT is still controversial. Our case and review illustrates how the routine placement of a malpositioned hemodialysis catheter in a young man can lead to the serious complication of RAT that necessitated cardiac surgery after thrombolysis failed. We describe the successful surgical management of a hemodialysis catheter-induced RAT and suggest that in cases of large, mobile RATs with adherence to both atrial wall and catheter, suspicion or evidence of pulmonary embolus (PE), and low-risk surgical candidates, open thrombectomy may be an optimal and definitive treatment.
