Lack of association between hemorheological alterations and upper-extremity deep vein thrombosis.

Introduction: There is an association between rheological alterations and lower extremity deep vein thrombosis, although no research has been carried out regarding the possible influence of rheological alterations in the development of venous thrombosis in the upper limbs. Materials and methods: We have determined in 54 patients (23 male, 31 female; aged 35 ± 11 years) with primary upper extremity deep vein thrombosis (UEDVT), and in a well matched control group of 87 subjects (41 male, 46 female; aged 36 ± 12 years) the rheological profile (blood viscosity, plasma viscosity, fibrinogen, erythrocyte aggregation, erythrocyte de- formability) along with plasma lipids (total cholesterol and tr…
