Core Tip

Core tip: The common presence of two thrombophilic defects increases the thrombotic risk several folds above the risk of a single defect and these tend to occur at an earlier age as seen in our case. Also the risk of recurrent thrombosis is significantly increased among these heterozygotes. Indefinite anticoagulation with oral anticoagulants (goal International Normalized Ratio = 2-3) is recommended for high risk patients like our case with thrombosis at unusual sites (e.g., mesenteric vein), and heterozygosity for both factor V Leiden and prothrombin G20210A mutations. These patients should avoid any hormonal therapy and family members should be screened for underlying prothrombotic condition.
