Abstract
Summary DVT is a frequent cause of admission to the ED. It is a major cause of morbidity and mortality. Complications ranges from the more common chronic venous stasis, predominantly in the lower extremity, to the much more serious state of PE. Two thirds of episodes manifest as DVT and one third as PE with or without DVT. DVT is not a clinical diagnosis, and imaging is required to make a definitive diagnosis. POCUS is the primary emergency ultrasonographic application in the diagnosis of DVT. DUS, venography, MRI, and nuclear imaging techniques are also used for DVT diagnosis. Venography is the gold standard for the diagnosis of DVT, but US has become the first choice as a diagnostic test due to its easy use, accessibility, lack of radiation, no need for contrast, high specificity, and high sensitivity. Compression ultrasound is an accurate noninvasive method for diagnosis of deep vein thrombosis (DVT). t is performed at two basic proximal points (femoral and popliteal) and relies on the dynamic evaluation of the compression ability of the venous system. So, in this study; we aimed to evaluate the accuracy of ultrasound 2PCT in diagnosis of lower limb DVT in ED.will lead to limitation of mobli ation of This unstable patients, thus prevent thrombus to propagate to lungs (tulmonary Embolism) and toovercome longer ED stays, availability and the time‐ consuming nature of imaging especially in crowded EDs This study was conducted on fifty (50) patients with suspected DVT in Tanta University Emergency Hospital in a duration of one year on patients suspected to have deep vein thrombosis using Well’s criteria. comparing the accuracy of 2PCT done by emergency physicians and duplex ultrasound done by radiology physicians. Patients presented with suspected lower extremity DVT were recruited in the study. Each patient underwent 2PCUS performed by ED physician. The ED physician recorded the results then referred the patient to the Radiology Department for duplex ultrasound examination.
