In rare cases of thromboembolic diseases developing in young age, venous and arterial thromboembolism can occur simultaneously.To detect the venous and the arterial risk factors in a severe thrombophilic family. A 47-years-old female with severe atherosclerosis and recurrent deep vein thrombosis, and 6 members of her family were analysed.The following haemostatic and molecular genetic investigations were performed: besides the rutin haemostatic parameters, risk factors for venous thrombembolic disease, risk factors for venous and arterial thrombosis (plasma homocysteine level, MTHFR C677T polymorphism) were determined. This panel was completed with the measurement of lipoprotein (a), von Willebrand factor, plasminogen activator inhibitor-1 antigen, serum total cholesterin, HDL cholesterin, C reactive protein and PIA2 variant. The propositus was proven to have type I antithrombin deficiency, elevated homocysteine level, homozygous MTHFR C677T polymorphism, elevated Lp(a), vWF:Ag, and PAI-1:Ag levels.All family members had a combination of cardiovascular risk factors (in 4 cases elevated homocysteine level, in 3 cases elevated Lp(a), in 2 cases elevated vWF:Ag, in 4 cases increased PAI-1 level). These risk factors were combined in three cases with type I antithrombin deficiency. Despite of the presence of atherosclerotic risk factors in the family, arterial thrombotic disease could be detected only in two patients with antithrombin deficiency.The results of the investigated family indicate that in case of combination of venous and arterial thromboembolic risk factors, antithrombin deficiency may contribute to the manifestation of arterial thromboembolic diseases.

Intracardiac manifestation of hepatocellular carcinoma (HCC) is a rare condition and an uncommon finding even at autopsy. Pulmonary tumor embolism as a presenting feature of HCC has been published only twice previously. In our case report, a 63-year-old man presented with high fever and six episodes of recurrent pneumonias during the last half year. Echocardiography was performed, a solid mass was found in the right atrium. Transesophageal echocardiography proved a tumor mass in the inferior vena cava (IVC) extending into the right atrium, abdominal ultrasound revealed tumor mass in the IVC and a solid tumor in the liver. Combined liver and heart surgery was attempted in order to remove the tumor mass from both the liver and the right atrium. Acute cor pulmonale occurred during tumor removal from the right atrium and the patient expired. In addition to local factors the possibility of embolization should arise in the background of recurrent pneumonia. Occult carcinoma must be included in pos-sible causes of recurrent pulmonary embolism. Searching for primary malignancy should include HCC as frequent cause of hypercoagulability. In case of HCC, echocar-diography is suggested because of the possibility of expansion in IVC or right atrium and tumor-embolization.
