Clinical analytic diagnostic assessment of deep vein thrombosis of lower limbs

BACKGROUND: Diagnosis of deep-vein thrombosis (DVT) of lower limbs has chan ged in recent years, The objective of our study was to analyze the diagnost ic accuracy of a combination of clinical and epidemiological data and the D -Dimer plasma levels in this entity. PATIENTS AND METHODS: Clinical (symptoms and signs) and epidemiological dat a, personal and family history, and D-dimer plasma levels or positivity wer e reviewed, on the admittance, in 108 patients to whom a phlebography was p erformed due to a suspected DVT. RESULTS: hlebography was positive in 76 cases (70.37%), Logistic regression analysis determined a prediction model of the diagnostic of DVI including a combination of both D-dimer plasma levels or positivity and pain along th e deep venous involved area, CONCLUSION: Combination of D-dimer testing and pain along the distribution of the deep venous area is useful as an initial diagnostic approach to the DVI of the lower limbs.
