Venous thromboembolism in anorexia nervosa: four cases from a specialized unit. Indication for thromboprophylaxis?

Background: Venous thromboembolism (VTE), which includes deep vein thrombosis (DVT) and pulmonary embolism (PE), is a major cause of mortality and morbidity. VTE may occur asymptomatic or subclinical. Fluid retention during intensive re-nutrition or rapid weight changes are well-known phenomena in anorexia nervosa (AN) and may represent a significant risk factor for VTE.
