Dr. Rathbun has been principal investigator in several research projects regarding pulmonary embolism and deep-vein thrombosis. Dr. Rathbun has published and presented both locally and nationally. She participated on the U.S. Surgeon General's task force for awareness of deep-vein thrombosis in Washington, DC. Currently, she serves as secretary to the Society of Vascular Medicine and chair of the education committee for the Venous Disease Coalition. Suman Rathbun received her doctorate of medicine at the University of Texas at San Antonio, Texas in 1994.

    Abstract:

    D-dimer is used in the clinical evaluation of suspected venous thromboembolism (VTE). Newer measurement methods show high sensitivity for this test, and in combination with pretest probability assessment, have a high negative predictive value for exclusion of VTE, obviating the need for many imaging procedures, optimizing healthcare resource utilization. This presentation will highlight the evidence supporting the clinical utility of D-dimer in VTE: upper extremity, lower extremity, recurrent lower extremity DVT and pulmonary embolism. The American Society of Hematology 2018 updated clinical practice guidelines outlining an evidence-based strategy for the diagnostic evaluation of VTE will be reviewed.

     

    Learning Objectives: 

    • Review the measurement of D-dimer and sensitivity/specificity for the clinical evaluation of suspected venous thromboembolism.
    • Describe the clinical utility of D-dimer in the diagnostic management of suspected upper extremity, lower extremity deep vein thrombosis, recurrent deep vein thrombosis and pulmonary embolism.
    • Review the American Society of Hematology practice guidelines 2018 for the Diagnosis of Venous Thromboembolism.
