Majority of Pulmonary Thromboembolism (PE) results from clot fragmentation of lower limb Deep Venous Thrombosis (DVT) . Non-invasive testing of the lower limb, such as Compression Ultrasonography (CUS), is the gold standard for the routine diagnosis of DVT. Free-Floating Thrombus (FFT) is present in 10-26% of thrombi detected with ultrasound and is often considered being a risk factor for PE in patients with DVT. To the best of our knowledge, this is the first report in the medical literature on 3 cases illustrating the detrimental consequence of mechanical compression effect on lower limb DVT. Using Doppler sonography, vein patency can be evaluated with dynamic tests that increase or accelerate venous flow: compression of muscles upstream from the probe or limb rising produces enhanced Doppler signals in normal veins. A free-floating thrombus (FFT) may be detected in 10-26% of thrombi detected with ultrasound and is considered a risk factor for pulmonary embolism . Few cases where dislodged FFT caused PE have been reported.

The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
