“…Ultrasound is sometimes not feasible due to obesity, edema, bandages, or plaster casts, and ultrasound of pelvic veins are prone to be problem-ridden (2,3). These difficulties may be overcome using MRI, and several quite different MRI venography techniques have been developed and reported.…”

“…Four patients had DVT of the right limb, and mean symptom duration was 8.3 days (range, [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Figure 3 shows examples of patients with DVT and direct and indirect findings of venous thrombosis in calf, knee, and thigh in corresponding images of the two MRI techniques.…”

“…Another problem is diagnostic imaging in patients presenting with recurrent, acute, or chronic DVT. These challenges can be overcome by use of MRI (2)(3)(4). Finally, MRI may provide valuable additional diagnostic information and establish differential diagnoses since this method also visualizes adjacent soft tissues and other vessels; i.e., superficial veins and arteries.…”

Purpose: To assess image quality, vessel visualization, preliminary diagnostic properties, and interobserver variability of a novel balanced turbo field echo (b-TFE) sequence and contrast-enhanced T1 fast field echo (CE-FFE) sequence with blood pool agent (BPA). Materials and Methods:A total of 15 healthy volunteers and six patients with ultrasound-verified proximal deep vein thrombosis (DVT) were examined from the inferior vena cava (IVC) to the proximal calf veins.Results: The great majority of deep veins were completely visualized on both sequences. In healthy volunteers the IVC was completely visualized in five b-TFE and 11 CE-FFE scans, and partially in seven b-TFE and four CE-FFE scans (P ¼ 0.008). Poorest image quality was in the pelvis. Contrast-to-noise ratio (CNR) was higher on b-TFE compared to CE-FFE, with significant difference in calf images (P ¼ 0.036). Sensitivity was 100% for proximal DVT with both methods. Specificity was 70% (CE-FFE) and 80% (b-TFE) for proximal femoral DVT; 100% in distal femoral. Interobserver reliability was kappa 1.0 (b-TFE), 0.9 (CE-FFE) for proximal, and overall poor for distal DVT.Conclusion: Contrast-enhancement did not add valuable information in visualizing deep veins of the lower limbs compared to b-TFE, though the IVC was slightly better visualized. Diagnostic properties and interobserver reliability of both sequences were good for proximal DVT and poor for distal DVT.

“…MRI venography and conventional venograms remain superior to Doppler US for detection of pelvic DVT, however majority of DVT post TKR occur in the lower calf and only 5-10% of DVT following THR occur in the upper mid-upper leg or pelvis [10]. Moreover, as this study is intended to develop recommendations regarding assessment and management of VTE within a routine clinical setting, the convenience, availability and feasibility of Doppler US over other imaging modalities promotes its use.…”

Background and aims: Anti-coagulation is an important component of post-operative Venous-Thombo-Embolic (VTE) prophylaxis but can be associated with significant complications including hemorrhage. Current guidelines favour anti-coagulation for ≥ 14 days with little evidence evaluating the efficacy of anticoagulation <14 days. Our study hypothesizes that short course Low-Molecular-Weight-Heparin (LMWH for 5-7 days) in combination with Calf Compression Device (CCD) is equally effective as standard therapy LMWH (14 days) in preventing VTE and related events amongst patients undergoing Total-Knee-Replacement (TKR).

“…MRV has the advantage over US in evaluating veins above the inguinal ligament, as 20 % of DVTs are isolated to the pelvic veins [28]. MRV may be superior to US for determining the chronicity of DVT, although this has not been well studied [2,29].…”

SANTRAUKAReikšminiai žodžiai: giliųjų venų trombozė, kompresinis ultragarsinis tyrimas, daugiasluoksnė kompiuterinė tomografija, magnetinis rezonansas, venografija. Venų tromboembolija (VTE) -tai dvi tarpusavyje susijusios patologijos: plaučių embolija (PE) ir giliųjų venų trombozė (GVT). Giliųjų venų trombozė išlieka svarbi sveikatos sistemos problema, kadangi yra susijusi su komplikacijomis, turinčiomis aukštą sergamumo ir mirtingumo rodiklį: ūminė ir lėtinė plaučių embolijos, plautinė hipertenzija ir potrombozinis sindromas. Paprastai GVT prasideda blauzdos venose, bet gali tęstis proksimaliau ir sąlygoti gyvybei pavojingą plaučių emboliją. Klinikinėje praktikoje labai svarbi šios ligos profilaktika ir gydymas, tad aktuali yra ankstyva ir tiksli diagnozė, įvertintant tikslią GVT vietą ir apimtį. Apibendrinus literatūros duomenis, straipsnyje apžvelgiami radiologinės diagnostikos metodai kojų giliųjų venų trombozei nustatyti, radiologinių tyrimų privalumai ir trūkumai. ABSTRACTKey words: deep vein thrombosis, compression ultrasound, multidetector computed tomography, magnetic resonance, venography. Venous thromboembolism consists of two related conditions: deep vein thrombosis and pulmonary embolism. One-third venous thromboembolism cases are manifested as pulmonary embolism and two-third present with deep vein thrombosis alone. Deep venous thrombosis remains an important health care problem as it is related with the complications having a high morbidity and mortality rate: acute and chronic pulmonary embolism, pulmonary hypertension and post-thrombotic syndrome. It is considered the third most common acute cardiovascular disease after ischemic heart disease and stroke and effects millions of people worldwide. Conventional venography was the gold standard in deep vein thrombosis diagnosis and the only imaging test for a long time in order to specify the suspected deep vein thrombosis in legs, pelvis or inferior vena cava [1,2]. Presently contrast x-ray venography is applied very seldom in conventional medical practice. Contrast x-ray venography is particularly helpful for assessing recurrent acute deep vein thrombosis in patients with a prior history of deep vein thrombosis in whom venous anatomy is often complex and difficult to evaluate using other methods [3] or when to remove an inferior vena cava filter. Conventional venography is presently replaced with non-invasive or less invasive radiological examination methods: the firstchoice method is ultrasound, but there are also other ones -computed tomography venography and magnetic resonance venography. Ultrasound is the imaging examination of choice for suspected lower extremity deep venous thrombosis. Ultrasound has high sensitivity (range, 93.2 %-95.0 %; pooled sensitivity, 94.2 %) and high specificity (range, 93.1 %-94.4 %; pooled specificity, 93.8 %) for diagnosing proximal (thigh) deep vein thrombosis and much lower sensitivity (range, 59.8 %-67.0 %; pooled sensitivity, 63.5 %) for diagnosing distal (calf ) and pelvic veins thrombosis. Compression ultra...
