| Popis: | Introduction: Venous Thromboembolism (VTE) encompasses a wide spectrum consisting predominantly of deep venous thrombosis and pulmonary embolism. The value of Fibrin Degradation Product (FDP) of which, most common is D-dimer which is most commonly deployed to pre-diagnose venous thrombosis. Diagnosing it has always been a hard effort. It is produced when cross-linked fibrin is broken down; among patient who is suspected of having pulmonary embolism, blood D-dimer levels correlate with the probability of having pulmonary embolism. Aim: This study was done to analyse the sensitivity of plasma D-dimer for VTE. Materials and Methods: Retrospective case study of 76 patients with VTE in form of pulmonary embolism done at the Dhiraj Hospital, Sumandeep Vidyapeeth Deemed University, Vadodara from January 2019 to January 2020 for a period of one year. Prethrombolytic plasma was withdrawn and D-dimer quantification were measured using fully automatic stago coagulometer instruement (STA Compact Max). Sensitivity, Specificity, Negative Predictive Value (NPV) and Positive Predictive Value (PPV) was calculated and formulated in tables and graphs. Results: The sensitivity, NPV, specificity and PPV of the D-dimer was 95.65%, 76.92%, 66.66% and 92.95%, respectively. CT pulmonary angiography had a specificity of 80%, sensitivity of 92.75%, a NPV of 70.58% and a PPV of 95.52%. Conclusion: D-dimer is mostly the go to test for ruling out VTE especially pulmonary embolism, if the pre-test probability is intermediate. Rationale use of this test does help in prognostification and helps to achieve therapeutics faster and more effectively. |
