[Right Atrial Thrombus Formation as Complications in the Presence of Hemodialysis Catheter and Central Venous Catheter].

History Case 1: admission to hospital of a 65-year-old female patient with multiple cerebral infarctions after surgery due to a benign tumor for detection of cardiac source of embolism by echocardiography. During surgery a central venous catheter has been placed into the internal jugular vein. Case 2: admission to hospital of a 59-year-old female with urosepsis due to infectious urinary stasis due to dislocated double J-catheter and suspected endocarditis. A chronic hemodialysis catheter has been placed 4 months ago. Diagnosis/findings In both cases right atrial thrombotic formations could be detected by echocardiography. Further, morphological und functional changes of the right atrium and ventricle as well as the tricuspid valve could be observed. Therapy and course In case 1 the patient was treated with therapeutic anticoagulation with phenprocoumon. In contrast, surgery (thrombectomy) was recommended in case 2 due to the increased risk of cardiac thromboembolism and the morphological und functional impairment of the tricuspid valve. Conclusion Echocardiography permits the detection of thrombotic formations in the right heart. Therapeutic procedures should be defined individually and interdisciplinarily.
