OBJECTIVE To describe a novel missense mutation in the antithrombin gene associated with antithrombin deficiency type I in a 40-year-old man with retinal vein occlusion. DESIGN Investigational case report. RESULTS Ophthalmoscopy of the right eye showed hemicentral retinal vein occlusion. The patient's medical history was negative for glaucoma or cardiovascular risk factors. Screening for th...

BACKGROUND There is limited evidence, so far, as to the optimal management of women with a prior obstetric history of antepartum complications attributed to thrombosis. We aimed to investigate the contribution of close antepartum surveillance on pregnancy outcome among women with prior antepartum complications attributed to thrombosis. METHODS The study was conducted on all women who were del...

INTRODUCTION The absolute risk of deep venous thrombosis (DVT) and pulmonary embolism (PE) as well as extension and/or recurrence in superficial vein thrombosis (SVT) of the leg is considerable and underestimated. We retrospectively evaluated therapeutic management, thrombophilic risk factors and clinical outcome of SVT. METHODS A database search was performed for consecutive patients with a ...

OBJECTIVE The pathophysiology of non-traumatic osteonecrosis (ON) or avascular necrosis (AVN) of the femoral head remains poorly understood. Some studies have suggested the contribution of underlying thrombophilia as a mechanism; however, no specific thrombophilic factor has been consistently found in association with the disease. We are presenting data suggesting a role for endothelial cell ac...

OBJECTIVE To investigate the contribution of inherited and acquired thrombophilic defects to the clinical manifestations of mixed cryoglobulinaemia vasculitis. METHODS The following thrombophilic defects were investigated in 64 consecutive patients with HCV-associated mixed cryoglobulinaemia: aPLs, lupus anti-coagulant, homocysteinaemia, protein C and protein S concentrations, activated prote...

Major complications of heart transplantation include graft rejection, infection, graft arteriosclerosis, malignancy, and drug toxicity. Among these complications, infections and thrombophilic disorders are of particular interest owing to their major contribution to morbidity and mortality among heart transplantation patients. Thrombophilic disorders are caused by imbalance between hypercoagulat...

BACKGROUND Retinal artery occlusion (RAO) is an ischemic vascular damage of the retina, which frequently leads to sudden, mostly irreversible loss of vision. In this study, blood thrombophilic factors as well as cardiovascular risk factors were investigated for their relevance to this pathology. Thrombophilic risk factors so far not evaluated were included in the study. PATIENTS AND METHODS 2...

OBJECTIVE To compare the occurrence of thrombophilic disorders in patients with idiopathic osteonecrosis of the femoral head and patients with secondary osteonecrosis of the femoral head. METHODS Twenty-four consecutive patients were enrolled, with eight of them presenting idiopathic osteonecrosis and 16 presenting secondary osteonecrosis. The tests for detection of thrombophilic disorders we...

AIM To estimate the prevalence of inherited and acquired thrombophilic risk factors in patients with abdominal venous thrombosis and to compare the risk factor profiles between Budd-Chiari syndromes (BCS) and splanchnic vein thrombosis (SVT). METHODS In this retrospective study, 36 patients with abdominal venous thrombosis were studied. The patients were divided into Budd-Chiari group (hepati...
