Calf muscle tears are relatively common. They can be identified well as incidental findings using duplex sonography when performing a lower extremity venous Doppler exam. A case is presented of a 43-year-old male patient who underwent a sonogram to diagnose deep vein thrombosis. The exam results demonstrated patent and compressible common femoral, femoral, popliteal, and calf veins without evidence of deep vein thrombosis. As the sonographer was documenting the popliteal fossa, a complex fluid-filled structure within the left gastrocnemius muscle was identified. The diagnosis was reported as a gastrocnemius muscle tear. This case demonstrates a fairly common incidental finding, gastrocnemius muscle tear, when performing a venous Doppler exam.

SummaryWithout any doubt colour duplex sonography was an enormous progress in angiological and/or phlebological diagnostics. Starting with the directional Doppler sonography, the large spectrum of phlebological diagnostics by colour duplex sonography is presented. Colour duplex sonography is used for a) the fundamental, morphologically and haemodynamically based diagnostics of deep vein thrombosis, of the insufficiency of subfascial and epifascial veins and for differential diagnostic delimitations (of arterial disorders, lip- and lymphedema, Baker-cysts, haematomas and so on), b) intrainterventional controls (steering of endovenous catheters and of foam sclerotherapy), c) the postinterventional assessment of results and disease course (definitively successful elimination of refluxes, relapses, complications as deep vein thrombosis and so on). Finally, the optimal position of the patient for duplex examination – supine or standing – is discussed, and methodical developments of the angiologic-phlebological diagnostics with ultrasound devices are described. Conclusion: In many cases duplexsonography avoids invasive examinations. It is part of the obligatory medical education in the field of phlebology.

A total of 50 legs in 34 consecutive patients with clinically suspected deep vein thrombosis (DVT) were evaluated both with colour-coded duplex sonography and phlebography, the tests being performed immediately following each other without the examiner knowing the result of the other procedure. Contrast phlebography was regarded as the standard for diagnosis. All the sonograms were considered to be technically adequate. The overall diagnostic accuracy, taking the leg as a whole from the ilio–femoral segment to the calf, was 92% and the sensitivity 78%. The accuracy in the femoral vein was 92%, sensitivity 64%. In the calf the accuracy was 90% and sensitivity 81%. although no attempt was made to localize or quantify the thrombus. The accuracy of the diagnosis of thrombus was not improved by the use of the colour-coded duplex facility. The main advantage of colour-coded duplex sonography over conventional duplex scanning is the easier identification of the venous system making it faster to perform. It is suggested that colour-coded sonography is a useful primary investigation for patients suspected of DVT or pulmonary embolism, but that about a third of patients will require contrast phlebography if the sonogram is negative or technically inadequate. It is emphasized that phlebography remains the most accurate method currently available for the diagnosis of DVT and using low osmolar contrast media is well tolerated and impressively safe.

Abstract Background Deep vein thrombosis (DVT) is common in critically ill patients with Coronavirus disease 2019 (COVID-19) and may cause fatal pulmonary embolism (PE) prior to diagnosis due to subtle clinical symptoms. The aim of this study was to explore the feasibility of bedside screening for DVT in critically ill COVID-19 patients performed by physicians with limited experience of venous ultrasound. We further aimed to compare inflammation, coagulation and organ dysfunction in patients with and without venous thromboembolism (VTE). Methods This observational study included patients with COVID-19 admitted to the intensive care unit (ICU) of a tertiary hospital in Sweden and screened for DVT with proximal compression ultrasound of the lower extremities between April and July 2020. Screening was performed by ICU residents having received a short online education and one hands-on-session. Pathological screening ultrasound was confirmed by formal ultrasound whereas patients with negative screening underwent formal ultrasound on clinical suspicion. Clinical data, laboratory findings and follow-up were extracted from medical records. Results Of 90 eligible patients, 56 were screened by seven ICU residents with no (n = 5) or limited (n = 2) previous experience of DVT ultrasound who performed a median of 4 (IQR 2–19) examinations. Four (7.1%) patients had pathological screening ultrasound of which three (5.6%) were confirmed by formal ultrasound. None of the 52 patients with negative screening ultrasound were diagnosed with DVT during follow-up. Six patients were diagnosed with PE of which four prior to negative screening and two following negative and positive screening respectively. Patients with VTE (n = 8) had higher median peak D-dimer (24.0 (IQR 14.2–50.5) vs. 2.8 (IQR 1.7–7.2) mg/L, p = 0.004), mean peak C-reactive protein (363 (SD 80) vs. 285 (SD 108) mg/L, p = 0.033) and median peak plasma creatinine (288 (IQR 131–328) vs. 94 (IQR 78–131) μmol/L, p = 0.009) compared to patients without VTE (n = 48). Five patients (63%) with VTE received continuous renal replacement therapy compared to six patients (13%) without VTE (p = 0.005). Conclusion ICU residents with no or limited experience could detect DVT with ultrasound in critically ill COVID-19 patients following a short education. VTE was associated with kidney dysfunction and features of hyperinflammation and hypercoagulation. Trial registration ClinicalTrials ID: NCT04316884. Registered 20 March 2020.

SummaryOutpatient treatment for acute symptomatic deep vein thrombosis (DVT) was shown to be safe for most patients. However, little is known whether patients treated on an outpatient basis were ambulating or predominantly resting, a factor which may be decisive for the outcome. In the present study 129 DVT patients were randomized to either strict immobilization for 4 days or to ambulate for ≥4 hours per day under supervision in order to show, whether the old concept of temporary immobilization is superior to early mobilization or not. The DVT diagnosis was based on duplex sonography; all patients were screened for PE at baseline and at day 4 by pulmonary ventilation-perfusion scanning, and were followed up for a total of 3 months. Clinically, changes in leg circumferences and leg pain were evaluated. The frequency of PE at baseline was 53.0% and 44.9% in the immobile and the mobile groups, respectively. During the 4 days observation period new PEs were found in 10.0% and in 14.4% of the immobilized and the ambulating patients (Δ 4.4%; 95% CI −0.5 to 13.8; χ2 = 0.596, p = 0.44). The occurrence of new PE was related to the presence of PE at baseline but not to other potential predictors. The magnitude of a decrease in leg circumferences and leg pain was comparable in both groups. No patient died during the 4 day observation period. The total 3 month mortality rate was 3.9% (5 patients; 2 from the immobile, 3 from the ambulating group). All 5 patient suffered from malignancies. The results of this study show in accordance with the trial hypothesis that, regarding the frequency of PE, immobilization is not superior to early mobilization, suggesting that early mobilization is safe.
