title: [Right atrial thrombosis with concomitant thrombus attached to a central venous catheter. Clinical case].
abstract: A clinical case of a patient in whom a right atrial thrombosis was casually discovered by transthoracic echocardiography is described. The hypothesis that also the central venous catheter (CVC) could be seat of thrombosis was done, and was confirmed by chest X-ray with dye injection in the CVC. A thrombolytic therapy with plasminogen tissular activator and with heparin infusion was started. After 24 hours from the beginning of therapy instrumental control were performed (transesophageal echocardiography ECOTEE, chest X-ray with dye injection in CVC), showing the completely dissolution of the thrombus. It is observed that, when in a patient with CVC high degree of thrombogenic factors (age over 60 years, presence of cardiac arrhythmias with ventricular hypokinesis, polyglobulia due to chronic obstructive pulmonary disease, CVC, low levels of antithrombin III) are present, the usual prophylactic measures (subcutaneous heparin, hydrophylic catheter) couldn't be sufficient to avoid superior caval vein thrombosis. The conclusion is drawn that these patient should be studied with ECOTEE and eco Doppler. Chest tomography and superior caval venography are also useful its early diagnosis of superior caval thrombosis.
