background: thrombophilia is a main predisposition to thrombosis due to a procoagulant state. several point mutations play key roles in blood-clotting disorders, which are grouped under the term thrombophilia. these thrombophilic mutations are methylenetetrahydrofolate reductase (mthfr, c677t, and a1298c), factor v leiden (g1691a), prothrombin gene mutation (factor ii, g20210a), and plasminogen...
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...
Cerebral venous thrombosis (CVT) and deep vein thrombosis or pulmonary embolism (DVT/PE) are associated with many risk factors. It is unclear why CVT occurs less often than DVT/PE. Age dependent risk factors may play a role. The aim of our study was to compare risk factors in a uniform age group of CVT and DVT/PE patients aged between 15 and 50 years. Thrombophilic markers and clinical risk fac...
The etiology and pathophysiology of cerebral sinus venous thrombosis (CSVT) in the paediatric population is still poorly understood, and the role of thrombophilic risk factors remains to be elucidated. In our multi-center case-controlled study we studied 46 patients with CSVT diagnosed from April 1996 to December 2003, consecutively referred for thrombophilia work-up. The results of thrombophil...
PURPOSE Atherosclerotic and thrombophilic risk factors may be causes of central retinal vein occlusion (CRVO). The aim of this study was to evaluate the prevalence of the aforesaid risk factors in patients with recurrent CRVOs and patients with a single episode of CRVO. METHODS Seventeen patients with recurrent CRVO and 30 with a single episode of CRVO were enrolled. The atherosclerotic risk ...
