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.

SummaryWe investigated gender differences in the prescription of prophylaxis against deep vein thrombosis (DVT) in 2,619 patients who developed acute DVT while being hospitalized for reasons other than DVT or were diagnosed with acute DVT as outpatients but who had been hospitalized within 30 days prior to DVT diagnosis. Men were 21% more likely than women to receive prophylaxis (OR 1.21, 95% CI 1.03–1.43; p = 0.021) after adjusting for DVT risk factors, including surgery, trauma, prior DVT, age, and cancer.

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.

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.

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.

Previous studies revealed a number of acquired risk factors predisposing to acute deep vein-thrombosis (DVT). Unfortunately many of these clinical or epidemiologic studies were not proper designed, since they didn't include consecutive patients, used no or different types of objective endpoints or collected the data retrospectively. In a prospective trial we evaluated 307 consecutive out-patients with clinically suspected DVT by using ascending venography, which confirmed suspicion in 136 (44%). A history of prior thrombotic episodes as well as factors predisposing to DVT including advancing age, obesity, smoking habits, cancer, chronic lung and/or heart disease, immobilization, pregnancy, childbirth, chronic liver disease, systemic lupus erythematosus (SLE), nephrotic syndrome, varicose veins, fractures or trauma or chronic arteriopathies of the legs, diabetes mellitus (DM), recent surgery and estrogen therapy were recorded in all patients. The results of our comparison of these risk factors with the outcome of venography indicate clearly a significant difference (chi-square test) between patients with and without DVT for the following: -previous documented thromboembolism, cancer (p < 0.01); -chronic lung and/or heart disease, age > 65 years, immobilization (p < 0.05). The frequency of pregnancy, childbirth, nephrotic syndrome and chronic liver disease among our patients was too low for providing sufficiently narrow confidence limits. Surprisingly the presence of varicose veins will decrease the possibility of DVT (p < 0.01). In all patients (n=3) affected by SLE clinical suspicion was confirmed. Obesity, smoking habits, recent trauma or fracture or chronic artheriopathies of the legs, DM, recent surgery and estrogen therapy were not associated with an increased risk of thrombosis, since their presence in both groups was approximately the same.

Objective Recently, the differences in age or sex of deep vein thrombosis (DVT) patients have been widely debated. However, close analyses of the differences in limb, age and sex of Chinese DVT patients have been scarcely reported. The purpose of this research is to study the differences in limb, age and sex of DVT patients. Methods A total of 783 consecutive DVT patients were retrospectively reviewed. Patients with an acute presentation of DVT were diagnosed by means of compression ultrasonography or venography. Clinical characteristics and provoked risk factors were analyzed. Results There were three frequency peaks including two smaller peaks at age 20–24 and 70–74 years, and the largest peak at age 45–59 years. The most significant risk factors affecting different age groups were as follows: pregnancy/puerperium for age ≤39; fracture and hysterectomy for age 40–64; fracture and malignancy for age ≥65. DVT frequency rate provoked by malignancy was higher in right DVT than left DVT (15.8% vs. 4.6%; p < 0.001). Left DVT was more common than right DVT (582 vs. 158). Left DVT tended to occur in females (male:female, 40.5%:59.5%), and right DVT in males (male:female, 74.7%:25.3%). DVT provoked by pregnancy/puerperium (56/63, 88.9%) or hysterectomy (27/30, 90.0%) was mostly located in left limb. Conclusion It is necessary to pay more attention to thromboprophylaxis for patients with the risk factors of pregnancy/puerperium, hysterectomy, fracture and malignancy, especially those over the age of 65. And further research into the cause of limb, age and sex differences in DVT occurrence is needed.
