A clinical score to rule out the concomitant presence of deep vein thrombosis in patients presenting with superficial vein thrombosis: The ICARO study

Superficial vein thrombosis (SVT) is commonly encountered in clinical practice. Recent studies have suggested that the concomitant presence of deep vein thrombosis (DVT) or pulmonary embolism (PE) at the time of SVT diagnosis is not uncommon, thus increasing the interest on this disease. Whether this coexistence is predicted by specific risk factors remains unknown.To evaluate potential risk factors for DVT coexistence in patients presenting with acute objectively diagnosed SVT of the lower limbs and to develop a simple score entirely based on clinical variables to define the pre-test probability of DVT in these patients.A multicenter, retrospective cohort study on SVT patients was conducte…
