Finding the Accuracy of Doppler USG in diagnosing DVT A Cross-sectional Study.

Abstract

Background: DVT is one of the serious vascular problems that can lead to pulmonary embolism complications and even death. Identification of the condition is very important in order to avoid negative consequences and achieve a favorable prognosis. Doppler ultrasound is an imaging technique with real-time with flow or velocity information, and it is the preferred modality for diagnosing DVT.

Objectives: To assess the degree of precision of Doppler ultrasound in detecting DVT & comparing its credibility in a sample of 100 patients, with the clinical signs & other investigative tools.

Study Design : A Cross sectional Study.

Place and duration of Study. Department of Radiology Qazi Hussain Ahmad Hospital Nowshera Kpk from 05 july-2023 to 05 july 2024

Methods: This cross-sectional study enrolled 100 patients with clinically suspected DVT. Doppler ultrasonography with acute and chronic thigh vein compression, normal and pathologic venous blood flow velocity and thrombus visualization. Comparisons were made with clinical presumptive diagnosis and laboratory analysis. An exploratory study approach was used, and statistical analysis involved sensitivity, specificity, SD, and p-values, to enhance the study findings interpretation.

Results: Out of one hundred patients, Doppler ultrasound proved Deep vein thrombosis in sixty five cases. Sensitivity was 92%, and specificity 88%. The mean diagnostic accuracy was 90.5% (SD ±3.2). It was obtained p<0.01, which mean there was a statistical significant. In the present study, Doppler USG was successful in identifying the thrombotic group from the non-thrombotic group.

Conclusions: Differentifications have shown that Doppler ultrasound is highly effective in diagnosing DVT with the aiding of early identification and intervention mechanisms. The noninvasive characteristic also makes it suitable for application as a first-line investigation tool
