Objective: To evaluate objectively the effect of compression therapy in patients with different degrees of calf muscle pump impairment following deep vein thrombosis. Design: Prospective study. Setting: Second Department of Surgery, Tottori University School of Medicine, Yonago, Japan. Patients: Twenty-one lower extremities in 16 patients and 23 lower extremities in 13 healthy control subjects. Intervention: Application of standard compression elastic stockings (30–40 mmHg compression at the ankle) and high compression elastic stockings (40–50 mmHg at the ankle) (Sigvaris, Sweden). Main outcome measures: Comparison of expelled volume measured by ambulatory strain-gauge plethysmography. Results: Calf pump function after deep vein thrombosis was classified into three grades (normal, compensated and failed) by the expelled volume. The expelled volume increased from 0.4 ml/dl (SD 0.2) to 0.9 ml/dl (SD 0.5) following the application of strong compression. Conclusion: Compression therapy is haemodynamically effective only when using strong compression (40–50 mmHg) in patients with post-thrombotic syndrome.

SummaryDoppler ultrasound flow examination, strain gauge plethysmography and contrast venography were performed in 160 lower limbs of 80 in-patients. Deep vein thrombosis (DVT) was suspected in 87 limbs. Using measurement of venous stop-flow pressure, the Doppler method had an overall sensitivity of 83%. By combined use of Doppler and Plethysmography, sensitivity was increased to 96%. Specificity was 62% and 51%, respectively. With a positive and a negative predictive value of 80% and 73%, respectively, the combination of both non-invasive methods cannot reliably replace venography in the diagnosis of DTV, although all (40/40) thromboses proximal to or involving the popliteal segment were detected by either Doppler and Plethysmography or both.After exclusion of 14 patients (18%) suffering from conditions known to alter the results of these non-invasive methods, the positive predictive value of abnormal findings in both Doppler and Plethysmography was increased to 94% for suspected limbs, whilst negative predictive value of both negative Doppler and Plethysmography was 90%, allowing the avoidance of venography in these patients.

Patients are frequently referred to hospital for exclusion of deep vein thrombosis (DVT); however, the diagnosis is only confirmed in 12% of those undergoing investigation. An effective strategy is required, which minimises the number of negative investigations, while safely excluding or confirming the diagnosis. This study investigates the combination of clinical risk scoring and strain-gauge plethysmography in the initial assessment of patients with suspected DVT. A survey was conducted of 1300 patients referred with suspected DVT over the course of a year. The results of this investigation were comparable to previous clinical trials and supports the use of strain-gauge plethysmography combined with clinical risk score in a busy acute medical unit.

Deep vein thrombosis (DVT) of the lower extremities has a high incidence and is insidiously fatal. Detachment of the thrombus can quickly cause death. Early detection and timely treatment are key to the treatment of DVT. This study is the first to report the clinical value of an inferior vena cava nanofilter combined with thrombolytic catheter for intravenous thrombolysis in DVT. The study found that the inferior vena cava nanofilter combined with the thrombolytic catheter has a significant effect on the treatment of DVT, which greatly reduces the circumference difference of the upper and lower legs, reduces the levels of fibrinogen, high-sensitivity C-reactive protein, and D-dimer, reduces the occurrence of complications, and is safe and worthwhile promotion.

Key Points Immediate compression therapy after DVT is associated with a 20% absolute reduction of RVO. The reduction of residual thrombosis is associated with an 8% absolute reduction of postthrombotic syndrome at 24 months.

One-hundred-and-eleven consecutive patients who were referred for routine phlebography because of clinically suspected deep vein thrombosis (DVT) were also investigated with a new, simplified, computerized strain-gauge plethysmograph (Phlebotest, Eureka AB). An occlusion plethysmograph curve was obtained from each leg simultaneously. Four different numerical parameters were defined and determined from this curve. These parameters were correlated with the phlebographic diagnosis. Three of the parameters of the plethysmograph curve correlated well with the phlebographic diagnosis, which proved correct in 54 patients without DVT, including two false negative cases, and in 12 patients with thrombosis. In 45 patients, plethysmography alone was not sufficient to establish a diagnosis. The plethysmograph described is easy to handle and is suggested for use in selecting those patients, with or without thrombosis, who do not require supplementary phlebography.
