Among bleeding disorders, hemophilia A, hemophilia B and von Willebrand diseases are the most commonly occurring, whereas deficiencies of other coagulation factors are rare worldwide. Unlike hemophilias, which are X-chromosome linked disorders, the inheritance pattern of the rare coagulation factor deficiencies is generally autosomal recessive. In literature, association of these factor deficie...

Exogenous hormones are used by more than a hundred million women worldwide as oral contraceptives or for postmenopausal hormone replacement. Oral contraceptives increase the risk of venous thrombosis, of myocardial infarction, and of stroke. The risk is highest during the first year of use. The venous thrombotic risk of oral contraceptives is high among women with coagulation abnormalities and ...

 Background: Type 2 diabetic mellitus patients are amongst the most susceptible groups to vascular abnormalities, which predominantly lead to myocardial disease. The hypercoagulable state has been widely studied by researchers as being the major suspicious mechanism facilitating the consecutive chain of molecular events leading to these complications. However, there is no consensus on the defin...

A 64-year-old woman newly diagnosed with IgG-λ type multiple myeloma was admitted for induction therapy. At the time of admission, she presented with petechial hemorrhage of the skin despite having no abnormalities in her coagulation or platelet function test results. During hospitalization, she developed severe melena. Small bowel endoscopy revealed multiple small ulcers in the jejunum. During...

The authors in this article record their experience with eight-four patients with abdominal aortic aneurysms. Twenty-seven patients (32%) presented with ruptured aneurysms with an overall mortality of 56%. Of the unruptured aneurysms, 67% were operable with a mortality of 5.3%. The highest mortality amongst the patients with ruptured aneurysms was in the group who was shocked. In the group with...

BACKGROUND AND OBJECTIVES The role of thrombophilia in failing arteriovenous fistula (AVF) among patients with ESRD undergoing hemodialysis is not established. This study aimed to assess whether AVF primary patency is associated with thrombophilia and coagulation abnormalities. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This observational study screened 219 patients between 2002 and 2004 f...

Thrombosis is one of the major complications of polycythemia vera. Seventeen patients with polycythemia vera in good hematologic control were evaluated for abnormalities of the coagulation system. Activation of the intrinsic coagulation cascade was suggested by low levels of factor XII, prekallikrein, and kallikrein inhibitors in 12 of 17 patients. The group also demonstrated a significant inc...

STUDY OBJECTIVES Although in situ thrombosis is a prominent finding in lung vessels from patients with primary and secondary pulmonary hypertension, to our knowledge, plasma coagulation factors that might contribute to a hypercoagulable state have not been fully investigated. We hypothesized that the local coagulation environment in the lung vasculature is important to progression if not initia...

The usefulness and optimal timing of laboratory coagulation tests before obstetric extradural analgesia are controversial. Moreover, the significance of mild coagulation abnormalities during pregnancy remains unclear. We have assessed the reliability of coagulation tests performed several weeks before delivery as predictors of coagulation abnormalities during labour. Platelet count, plasma fibr...
