Venous Duplex Ultrasound - Legs. Your doctor has requested an ultrasound of your leg veins. Ultrasound is a procedure that uses sound waves to see inside your body. This procedure is performed to evaluate symptoms including leg pain or swelling, excessive varicose veins, shortness of breath, or suspected blood clots in your legs and/or lungs consequences of lower extremity arterial disease. A contemporaneous ABI, along with imaging, is com-plementary and supports the imaging ﬁndings or may suggest non visualized disease, or if discrepant, helps avoid pitfalls. Representative longitudinal color Doppler and/or gray scale images along with angle-corrected spectra Findings of venous insufficiency in the lower limb can usually be detected in connection with venous edema. Realization of compression therapy requires a prescription for stockings, motivation and guidance. In specialized care, correlating the edema and venous symptoms with color Doppler ultrasonography findings is essential The gender distribution of Doppler findings revealed the presence of lower extremity peripheral artery disease (LEAD) in 41 males and in 20 females, giving the male:female ratio of 2.05:1. However, this difference is not statistically significant (χ 2 = 1.151, df = 1, P > 0.05). Doppler ultrasound findings in diabetic patient A venous Doppler ultrasound is a diagnostic test used to check the circulation in the large veins in the legs (or sometimes the arms). This exam shows any blockage in the veins by a blood clot or thrombus formation. Normal Circulation. The veins return blood to the heart. There are two sets of veins in the legs

Chronic Venous Insufficiency Chronic venous insufficiency is impaired venous return which may cause lower extremity symptoms Although he had tachycardia post-thrombolysis for the next two days, his blood pressure returned to normal on the third day. 48-hours after giving thrombolytic treatment, the left lower limb venous doppler was done which was suggestive of a partial-lumen occluding the thrombus in popliteal vein extending from saphenopopliteal junction to mid. Doppler echocardiography is the use of Doppler ultrasonography to examine the heart. An echocardiogram can, within certain limits, produce an accurate assessment of the direction of blood flow and the velocity of blood and cardiac tissue at any arbitrary point using the Doppler effect. One of the limitations is that the ultrasound beam should be as parallel to the blood flow as possible
The pathophysiology of venous thrombosis has been famously described by Rudolf Virchow, known as the Virchow's triad, which includes stasis, endothelial injury, and hypercoagulability.  Venous thrombosis can be superficial venous thrombosis, or deep venous thrombosis (DVT), the latter will be the focus of this article. While the most common origins are in the extremities, where the lower.

Duplex sonography of the extremities is a non-invasive and valuable tool in detecting diseases in the blood vessels of the arms and legs. This post will cover the basic evaluation of the upper and lower extremity arterial systems. Indications 1. Detection of stenosis or occlusions in segments of the peripheral arteries. 2 Deep vein thrombosis. Dr Matt A. Morgan and Assoc Prof Frank Gaillard et al. Deep vein thrombosis (DVT) most commonly occurs in the lower limbs, however, are not uncommon in the upper limb and neck veins. Other types of venous thrombosis, such as intra-abdominal and intracranial, are discussed in separate articles The incidence of lower-limb DVT was 5.01% (21), including 11 proximal and 10 distal DVT. No patients had clinical pulmonary embolism. Using 247 venous duplex ultrasonography results for analyses of correlates with logistic regression analyses, no significant demographic or clinical predictive factors for DVT were found
Duplex ultrasound employs a combination of conventional ultrasound, color flow Doppler imaging and spectral Doppler analysis, and, in most cases, can be reported as complete bilateral or limited or unilateral studies depending on the location of the vessels in the study. The CPT nomenclature splits the duplex scan codes into sections for cerebrovascular arteries, extremit Lower Extremity Venous Duplex Ultrasound Chronic Venous Insufficiency.

Chronic venous insufficiency (CVI) causes pathophysiological changes in the lower-limb muscles, particularly the calf muscles, and limits ankle range of motion (ROM). These changes reduce functional activities and decrease quality of life (QOL). Although several studies have shown the benefits of exercise (strengthening the calf muscles to improve calf-muscle pumping and QOL) in patients with. All the patients had deep venous thrombosis of the lower limb confirmed with Doppler studies and duplex scan of the lower limb. Swollen lower limb was the commonest presenting symptom and sign. Prolonged sitting was the main factor in 9 out of eleven patients. CONCLUSIONS: Deep venous thrombosis may not be a rare condition in the young ambulant. limited bilateral noninvasive physiologic studies of upper or lower extremity arteries, (eg, for lower extremity: ankle/brachial indices at distal posterior tibial and anterior tibial/dorsalis pedis arteries plus bidirectional, doppler waveform recording and analysis at 1-2 levels, or ankle/brachial indices at distal posterior tibial and. The importance of functional right ventricular failure and resultant splanchnic venous congestion has long been under-appreciated and is difficult to assess by traditional physical examination and standard diagnostic imaging. The recent development of the venous excess ultrasound score (VExUS) and growth of point-of-care ultrasound in the last decade has made for a potentially very useful. shown that lower-limb resistance training can improve calf muscle pump function, ankle range of motion and lower-limb haemodynamics in people with venous ulceration (Kan and Delis 2001; Jull et al. 2009; O'Brien et al. 2013). Our group has also demonstrated that lower-limb endurance training (Klonizakis et al. 2009), but not upper-limb endur
