Objectives Ambient temperature (that impacts differently venous flow in superficial and deep veins) could have a different effect on the risk of superficial and deep venous thrombosis. We searched for a trimestral variation of the risk of superficial venous thrombosis among all lower-limb thrombotic events (lower-limb thrombotic events = superficial venous thrombosis + deep venous thrombosis). Methods We retrospectively analyzed the results of venous ultrasound investigations performed among 11,739 patients (aged 67 ± 19 years old, 56.1% males) referred for suspected lower-limb thrombotic events over a 12-year period. Chi-square test was used to compare the superficial venous thrombosis/lower-limb thrombotic events ratio observed by trimesters to a homogeneous distribution. Results The proportion of lower-limb thrombotic events were 30.7%, 28.8%, 31.1%, and 31.4% (Chi2: 0.133; p = 0.987) of total investigations, while that of superficial venous thrombosis among all lower-limb venous thrombotic events were 27.2%, 30.0%, 31.4%, and 31.0%, for the first, second, third, and fourth trimesters respectively (Chi2: 0.357; p: 0.949). Conclusion No trimestral variation of the superficial venous thrombosis/lower-limb venous thrombotic events ratio was observed.

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.

The present study is designed to evaluate the effectiveness of a thigh length sequential compression device (SCD) in the prevention of deep venous thrombosis (DVT) in patients undergoing hip operations (either fracture or elective). The night before the operation phleborheography, doppler ultrasound and, when possible, 125I fibrinogen scanning were used to evaluate venous flow in the patients’ legs. The patients identified as being free of DVT complications were then fitted with the compression sleeves. Following surgery the venous evaluation tests were repeated on alternate days to determine if DVT complications had developed. Evidence of DVT formation was identified in 10 of the 52 control patients (who received leg elevation only) and in 1 of the 52 treated patients (who received the SCD plus leg elevation). The chi square statistic demonstrates a significant difference between the two groups (P<.05).Data evaluation indicates that surgical approach and patient obesity did not contribute to the risk of DVT formation. However, patients who are either over the age of 66, females, or have suffered a hip fracture appear to be at greater risk than other groups. The amount of data in this study makes it difficult to evaluate with statistical significance the additional risk produced by other factors such as heart condition, previous history of clotting problems, estrogen therapy, etc.

Key Points Superficial vein thrombosis combined with an acquired thrombotic risk factor increases the risk of venous thrombosis 10- to 100-fold. If confirmed, these findings have important implications for the future prevention of venous thrombosis.

Abstract Superficial vein thrombosis (SVT) is regarded a self-limiting disorder, although the authors of recent studies showed that ultrasonographically diagnosed SVT is a precursor for venous thrombosis. We aimed to determine whether the same holds true for clinically diagnosed SVT and to what extent it is associated with thrombophilia in a population-based case-control study (ie, Multiple Environmental and Genetic Assessment of risk factors for venous thrombosis). We found that a history of clinical SVT was associated with a 6.3-fold (95% confidence interval [CI] 5.0-8.0) increased risk of deep-vein thrombosis and a 3.9-fold (95% CI 3.0-5.1) increased risk of pulmonary embolism. Blood group non-O and factor V Leiden showed a small increase in SVT risk in controls, with odds ratios of 1.3 (95% CI 0.9-2.0) and 1.5 (95% CI 0.7-3.3), respectively. In conclusion, clinically diagnosed SVT was a risk factor for venous thrombosis. Given that thrombophilia was only weakly associated with SVT, it is likely that other factors (varicosis, obesity, stasis) also play a role in its etiology.

Objective The aim of our study is to investigate the prevalence of silent pulmonary embolism in patients with deep venous thrombosis in the lower limbs and to evaluate the associated risk factors. Methods A total of 322 patients with acute deep venous thrombosis confirmed by CT venography or Doppler ultrasonography were studied. The diagnosis of silent pulmonary embolism was established by computed tomography pulmonary arteriography (CTPA). The association between covariates and the prevalence of silent pulmonary embolism in patients with deep venous thrombosis in lower limbs were assessed using chi-square test and multivariable regression. Results The incidence of silent pulmonary embolism was 33.5% (108 in 322 patients) in all patients with deep venous thrombosis in lower limbs. Chi-square test showed male gender, the right lower limb, proximal location of the thrombus, unprovoked venous thrombosis and coexisting heart diseases were related to a higher incidence of silent pulmonary embolism in patients with deep venous thrombosis in lower limbs. The multivariate regression analysis confirmed that the risk factors associated with silent pulmonary embolism in deep venous thrombosis patients included the right side and proximal location of the thrombus (odds ratio: 2.023, 95% CI: 1.215–3.368; odds ratio: 3.610, 95% CI: 1.772–7.354), unprovoked venous thrombosis (odds ratio: 2.037, 95% CI: 1.188–3.493), coexisting heart diseases (odds ratio: 4.507, 95% CI: 2.667–7.618). Conclusion Silent pulmonary embolism occurred frequently in patients with deep venous thrombosis in lower limbs. The right side, the proximal location of the thrombus, unprovoked venous thrombosis and coexisting heart diseases increased the risk for the occurrence of silent pulmonary embolism.

Background: Risk of subsequent deep vein thrombosis (DVT) following superficial vein thrombosis (SVT) is not fully appreciated. Mechanisms, time relations and risk factors for DVT arising upon earlier SVT remain unclear. The aim of this study was to analyze time relations between local symptoms of lower limb superficial vein thrombosis, duplex findings and onset of deep vein thrombosis during clinically evident course of SVT. Patients and methods: 46 patients with early (onset less than 72 hours prior to inclusion) clinical diagnosis of SVT, confirmed ultrasonographically were included in this prospective, multicenter study. Progress of pain, erythema and swelling in relation to subsequent ultrasound changes in size and localization of thrombus at 0, 7, 14 and 21 day of study has been recorded. Results: Local symptoms subsided completely during 3 weeks. At that time thrombus disappeared completely only in 26% of cases, in remaining cases decreased in size from average 117.5 mm to 43.0 mm. Thrombus regression was similar to venous blood outflow direction – proximal to femoral area. Thrombus propagation was observed following regression of local symptoms of SVT. 4 cases of DVT (8.7%) were diagnosed at 2–11 days. Conclusions: Local, clinically detectable symptoms of SVT regress incomparably quicker than thrombus in affected veins. Risk of further thrombus propagation extends well beyond the period of intensive local symptoms of SVT. Regression of thrombus in femoral area requires significantly more time than in popliteal or calf segment. Thrombus propagation is directed with blood flow towards femoral segment.
