OBJECTIVE: to determine the incidence of deep vein thrombosis and prophylaxis quality in hospitalized patients undergoing vascular and orthopedic surgical procedures. METHODS: we evaluated 296 patients, whose incidence of deep venous thrombosis was studied by vascular ultrasonography. Risk factors for venous thrombosis were stratified according the Caprini model. To assess the quality of prophylaxis we compared the adopted measures with the prophylaxis guidelines of the American College of Chest Physicians. RESULTS: the overall incidence of deep venous thrombosis was 7.5%. As for the risk groups, 10.8% were considered low risk, 14.9%moderate risk, 24.3% high risk and 50.5% very high risk. Prophylaxis of deep venous thrombosis was correct in 57.7%. In groups of high and very high risk, adequate prophylaxis rates were 72.2% and 71.6%, respectively. Excessive use of chemoprophylaxis was seen in 68.7% and 61.4% in the low and moderate-risk groups, respectively. CONCLUSION: although most patients are deemed to be at high and very high risk for deep vein thrombosis, deficiency in the application of prophylaxis persists in medical practice.

BACKGROUND: There is a knowledge gap with relation to the true incidence of deep vein thrombosis among patients undergoing vascular surgery procedures in Brazil. This study is designed to support the implementation of a surveillance system to control the quality of venous thromboembolism prophylaxis in our country. Investigations in specific institutions have determined the true incidence of deep vein thrombosis and identified risk groups, to enable measures to be taken to ensure adequate prophylaxis and treatment to prevent the condition.OBJECTIVE: To study the incidence of deep venous thrombosis in patients admitted to hospital for non-venous vascular surgery procedures and stratify them into risk groups.METHOD: This was a cross-sectional observational study that evaluated 202 patients from a university hospital vascular surgery clinic between March 2011 and July 2012. The incidence of deep venous thrombosis was determined using vascular ultrasound examinations and the Caprini scale.RESULTS: The mean incidence of deep venous thrombosis in vascular surgery patients was 8.5%. The frequency distribution of patients by venous thromboembolism risk groups was as follows: 8.4% were considered low risk, 17.3% moderate risk, 29.7% high risk and 44.6% were classified as very high risk.CONCLUSION: The incidence of deep venous thrombosis in vascular surgery patients was 8.5%, which is similar to figures reported in the international literature. Most vascular surgery patients were stratified into the high and very high risk for deep venous thrombosis groups.

Fifty-three patients were examined because of suspected deep venous thrombosis, by means of clinical examination, Doppler ultrasound and venography. Eighty-two legs were examined with all three methods. Venography was positive in 40 and normal in 42. The clinical examination was false positive in 4 legs and false negative in 6. The Doppler ultrasound studies gave false positive results in 3 legs and false negative results in 6. These results are better than those reported in the literature probably because the thrombosis extended to the popliteal vein or the more proximal veins in 38 of the 40 legs with deep vein thrombosis. This high percentage of upper leg vein thrombosis can be explained by the fact that 47 of the 53 patients were ambulant when they developed the signs and symptoms of thrombosis. It is concluded, that the clinical examination and Doppler ultrasonography can be used to diagnose deep vein thrombosis in ambulant patients in our clinic. We presume that the findings reported in the literature cannot be used indiscriminately as a basis for diagnostic strategies in other hospitals because of widely varying categories of patients, referral patterns and diagnostic criteria that are virtually impossible to standardize.

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.

Nephrotic syndrome (NS) is a state of hypercoagulability. In this paper, we sought to determine risk factors for the occurrence of deep vein thrombosis (DVT) in children with NS. The “with DVT” group included patients with decompensated NS and diagnosed with DVT. The “without DVT” group included the same patients, six to eighteen months prior to the episode of DVT, with decompensated NS but without DVT. Different prediction variables were analyzed. The odds ratio for the occurrence of DVT in patients with triglyceride levels ≥300 mg/dL was 3.14 (95% CI 1.14 to 8.64). For hematocrit levels ≥43% and for the presence of infection or a severe systemic event, the odds ratio was 4.37 (95% CI 1.23 to 15.53). The presence of significant risk factors for the occurrence of DVT in children with NS may serve as a warning for the occurrence of venous thrombosis.

Radiofrequency ablation (RFA) of the saphenous and perforator veins (“closure”) is a relatively newer option for treatment of venous insufficiency patients. A known complication of the RFA is deep vein thrombosis also known as DVT. The purpose of this study is to demonstrate the probability of acute deep venous thrombosis post radio-frequency vein ablation. This research also helped determine medical necessity of a postoperative venous duplex examination within 5 days post-procedure.

Background: Circulating Tissue Factor (TF) is associated with inflammation and may contribute to thrombotic events. Aim of this study was to analyze circulating TF activity and proinflammatory cytokines in patients with deep venous thrombosis. Patients and methods: Forty-eight patients with deep vein thrombosis and 45 control subjects were included. Venous blood samples were obtained at diagnosis for analysis of TF activity, TF antigen, prothrombin fragment F1 + 2, microparticles (expressing phosphatidylserine and supporting FXa generation), Interleukin (IL)-1beta, IL-6, IL-8, IL-10, IL-12 and Tumor-Necrosis-Factor-alpha (TNF). Results: TF antigen, activity and microparticles were similar in both groups: In contrast, a significant increase in plasma IL-6, IL-8 and F1 + 2 levels was found in thrombosis. This increase in IL-6 and IL-8 as well as F1 + 2 was not correlated with the extent of thrombosis, predisposing factors or onset of symptoms. Conclusions: Circulating TF and microparticles are not elevated in deep venous thrombosis. The increase in IL-6, IL-8 and F1 + 2 during thrombosis was not proportional to the extent or predisposing risk factors.

Acute deep venous thrombosis (DVT) of iliofemoral segment is one of the most dreaded presentations of venous thromboembolism, as it can not only compromise the function of the extremity but may also result in pulmonary embolism and even death. There are many causes for acute iliofemoral DVT, including underdiagnosed May-Thurner syndrome, hypercoagulable syndrome, and external compression on iliocaval segment. The available treatment depends on the acuity of the symptoms. Acute iliofemoral DVT can be treated with medical anticoagulation, pharmacomechanical therapy, including thrombolysis or surgical thrombectomy. Chronic iliofemoral occlusion may be treated with recanalization of the occluded segments with angioplasty stenting. This review contains 4 Figures, 4 Tables and 63 references Key Words: acute, angioplasty, deep venous thrombosis, iliofemoral, inferior vena cava, pharmacomechanical therapy, occlusion, stent
