Abstract

Purpose: Early diagnosis and treatment of venous thrombosis (VT) are essential in preventing pulmonary embolism (PE) and reducing the risk of recurrence. The objective was to assess the usefulness of the D-Dimer testing to rule out symptomatic VT in populations of patients receiving heparin in prophylactic doses. Methods: One hundred and twenty-three rehabilitation patients with medium or high risk for VT were investigated. Patients were affected by acquired cerebral diseases (n = 31), severe brain damage (n = 32) or orthopaedic surgical sequelae for major joint replacement or multiple limb fractures (n = 60). All patients were receiving prophylactic heparin doses. D-Dimer levels were assessed using Dimertest Latex Agglutination Assay in citrated plasma. Single blinded compression Doppler Ultrasound (DUS) examination was performed in conformity with international standards. Results: In this specific setting, good sensitivity and specificity of the D-Dimer test was confirmed in patients with acquired cerebral diseases during rehabilitation, whereas false positive results were found in most patients who had undergone major joint replacement, until several weeks after surgery. Conclusions: In rehabilitation patients receiving prophylactic heparin doses, the D-Dimer test seems to confirm high sensitivity and high negative predictive value for VT and PE. Relevant clinical variables seem to reduce the usefulness of the D-Dimer test as a screening tool for VT, at least in orthopaedic patients with joint prosthesis.
