Abstract

International audience; BACKGROUND AND OBJECTIVES: A high level of coagulant factor VIII is a well known risk factor for venous thromboembolism, but most studies have enrolled patients under 70 years old. This study aimed to test the hypothesis that an association also exists in the elderly. DESIGN AND METHODS: This hospital-based case-referent study took place at the Department of Internal Medicine and Chest Diseases, University Hospital, Brest, France. We enrolled 161 patients with a first episode of venous thrombosis and 239 subjects, referred for a clinical suspicion of venous thromboembolism which was subsequently ruled out. Factor VIII coagulant activity and plasma fibrinogen concentration were measured. RESULTS: High factor VIII coagulant activity was significantly associated with venous thromboembolism, irrespective of the age group. Patients over 70 years with factor VIII coagulant activity above 225% had a 2.4-fold increased risk of venous thromboembolism compared to those patients with levels below 130% (age- and fibrinogen-adjusted odds ratio: 2.6, 95% CI 1.1 to 6.1). INTERPRETATION AND CONCLUSIONS: Our results show that high levels of factor VIII coagulant, a determinant of venous thrombosis in adulthood, is also a risk factor in the elderly.

Abstract

Background: Thenar hammer syndrome is a very rare condition that mimics rheumatic diseases such as carpal syndrome tunnel, Raynaud's phenomenon, and hand synovitis. Objective: To describe the sonographic presentation of thenar hammer syndrome in a typical patient. Methods: Grey-scale sonography and colour Doppler imaging of the hands with an iU22 scanner (Philips) were performed. Results: In B mode, the lesion was seen as a large, rounded, heterogeneous area combining hypoechoic and echogenic components. Pseudoaneurysm was diagnosed based on presence of a cystic saccular formation arising directly from the adjacent artery and exhibiting an irregular thick wall with turbulent blood flow in the lumen. Colour Doppler showed blood flow in part of the lumen, the rest of which was filled with a thrombus seen as echogenic tissue. Conclusion: Sonography can help to diagnose thenar hammer syndrome. Angiography may be unnecessary in patients with normal colour Doppler findings. © 2010 Société française de rhumatologie.

Abstract

International audience; INTRODUCTION: The clinical significance of calf muscle venous thrombosis (CMVT) still remains a matter of debate. Detected by ultrasonography, they are overlooked by venography. This prompted us to evaluate the frequency of such localizations and their association to pulmonary embolism (PE). METHODS: Retrospective review of our database over a three-year period. All patients with an isolated CMVT were included. RESULTS: Isolated CMVT were detected in 106 patients (mean age 68.6 years; 65% women), that is 12.5% of all venous thromboses diagnosed in the vascular sonography unit over the study period Sixteen associated PE were detected (15%). CONCLUSIONS: Association of CMVT and PE is not infrequent. Whether or not such thromboses have the potential to extend into deep veins and/or to migrate into pulmonary circulation requires further studies.

Abstract

Coronary angiography is a recommended investigation in the preoperative assessment of aortic valve replacement for aortic stenosis in the absence of a reliable non-invasive diagnostic method. Ultrasonographic quantification of carotid artery intima-media thickness, being correlated to the severity of coronary atherosclerosis, could therefore be useful in the screening of coronary artery disease in severe aortic stenosis. The authors studied a group of 100 patients (69.5 +/- 8.5 years: 64 men) with severe aortic stenosis. A control group of 45 patients with coronary artery disease without valvular disease (69.5 +/- 6 years: 30 men) was used for reference. Significant coronary artery disease was found in 21 of the 100 study cases. The average intima-media thickness was 0.608 +/- 0.090 mm. There was no significant difference in intima-media thickness between the coronary and non-coronary patients of the study group (0.612 +/- 0.094 mm and 0.607 +/- 0.094 mm respectively). It was, however, significantly greater in the control group patients compared with the 21 coronary patients in the study group (0.699 +/- 0.082 mm and 0.612 +/- 0.094 mm; p = 0.0004). Finally, 71.1% of patients in the control group had atheromatous carotid artery plaques compared with 59% in the study group (p = 0.005). The measurement of carotid intima-media thickness does not allow detection of coronary patients in severe aortic stenosis. The finding of a lower intima-media thickness in this population compared with coronary patients without valvular disease suggests that aortic stenosis may have a protective effect on the wall thickness of carotid arteries.

Abstract

International audience; Contrast venography is the gold standard for the diagnosis of deep vein thrombosis in the lower limb extremities, but it fails to visualize deep veins like deep femoral vein and internal iliac vein. The internal iliac can be examined with duplex scanning if the technique and the examination conditions are correct. As reported in these two cases, thrombosis of these deep veins may lead to pulmonary embolism. The first case is a young female with venous thromboembolic disease in whom internal iliac vein thrombosis was documented only at the second examination. In the second case, deep femoral vein thrombosis appeared early in a comatose young male. This thrombosis may be classified as proximal muscular vein thrombosis. These two cases emphasize the importance of a duplex scanning examination performed with rigorous technique, whose the main limitation being examination conditions.

Abstract

Venous thrombosis is a common pathology that creates serious problems in public health. The diagnostic of thrombosis, particularly the determination of their relative ages can be efficiently accomplished by ultrasound imaging. This study intends to classify automatically the thrombosis ages by using a predefined learning base that depends on a prior knowledge of physicians. In practice, this learning base is affected by information imperfections of the type ambiguity since physicians cannot give exact thrombosis ages. Thus, the proposed learning base is constructed in a 3-tuple: observation, label, membership value in term of fuzzy logic for each class and not a 2-tuple as in the usual supervised Bayes classification application. By considering this fuzzy learning base", a method modeling simultaneously the concept of probabilistic uncertainty and ambiguity is proposed. In this approach, the probability for a given observation is considered on the membership value of each class and not on the class itself. At this level, the discussion focuses on two types of applications: the thrombosis ages classification and the definition of membership function by using a fuzzy learning base for classification., Papers from 23rd Annual International Conference of the IEEE Engineering in Medicine and Biology Society, October 25-28, 2001, held in Istanbul, Turkey.
