Hemophilia A and B are caused by deficiencies in coagulation factor VIII (FVIII) and factor IX, respectively, resulting in deficient blood coagulation via the intrinsic pathway. The extrinsic coagulation pathway, mediated by factor VIIa and tissue factor (TF), remains intact but is negatively regulated by tissue factor pathway inhibitor (TFPI), which inhibits both factor VIIa and its product, f...

BACKGROUND The hypercoagulable state associated with cancer imparts considerable risk for venous thromboembolism. Surgical resection of malignancies should theoretically reverse tumor-induced hypercoagulability. However, coagulation changes in cancer patients postresection have not been described thoroughly. Conventional coagulation tests are unable to detect hypercoagulable states. In contrast...

BACKGROUND AND OBJECTIVES Dexmedetomidine is a highly selective alpha2-adrenoceptor agonist used in anesthesia for its hypnoanalgesic and cardiovascular effects. Stimulation of alpha2-adrenoceptors may determine pro and anti-platelet aggregation effects through direct and indirect mechanisms. This study aimed at determining the effects of dexmedetomidine on coagulation evaluated by thromboelast...

We aim to present the case of a 5-week-old girl with severe respiratory failure placed on veno-venous extracorporeal membrane oxygenation (ECMO) that was then switched to veno-arterial ECMO. She required up to 60 units/kg/hr of heparin to keep her heparin level within the target range at .3-.7 units/mL. During the ECMO course, substantial thrombus formation was observed within the venous site o...

Hemophilia B is a rare X-linked disorder that may cause dramatic bleeding. Women account for only 3.2% of those clinically affected. The X-linked inheritance frequently delays the diagnosis in women and may expose the patient to an increased risk of adverse events. There is limited experience with these patients during labor and delivery. A 28-year-old primiparous woman with hemophilia B (bleed...
