Purpose: MR venography has been recommended for the evaluation of deep venous thrombosis. The purpose of our study was to determine the role of MR venography, in particular at the level of the pelvis where other diagnostic modalities show major limitations. Materials and Methods: Forty-three patients with clinical suspicion of deep venous thrombosis were examined by means of pelvic MR venography. In all cases, a 2D-TOF sequence was used with cranial arterial presaturation. In selected cases, i.e. when a small intraluminal filling defect was present, a cine-PC sequence was used in addition in order to exclude the presence of a pulsatility artifact as causing the filling defect. In all cases, contrast venography was also performed and considered to be the standard of reference. Results: MR venography showed 26 patients to be positive for deep venous thrombosis at the pelvic level. These positive results were correct in 25 cases. The analysis of the results provided values of sensitivity and specificity of respectively 100% and 94%, with an overall accuracy of 97.6%. Conclusion: Our results indicate that MR can provide highly accurate images, similar to those of contrast venography, in a noninvasive fashion. It is particularly useful in the pelvic region where the limitations of other imaging modalities are more evident.

Introduction. The aim of this study was to investigate the role of duplex Doppler ultrasonography in diagnosis of deep venous thrombosis (DVT) of the lower extremities. Material and methods. During a 2-year period, 860 patients were examined by duplex Doppler sonography. Among these, 619(72%) were women and 241 (28%) men, with the age-range of 16-91; (mean 56,2) years. Siemens Versa Pro color doppler was used, with 7MHz transducers. Findings were categorized into four categories: 1. deep venous thrombosis (DVT); 2. pathology predominantly related to superficial veins without DVT; 3. pathology of superficial and deep veins; 4. normal findings. Results. 185 (21%) patients had DVT, 366 (42.5%) patients had pre?dominant pathology of superficial veins: postthrombotic syndrome, superficial thrombophlebitis and varicose veins. 128 (14.9%) patients had pathology of superficial and deep veins. Normal findings were found in 181 (21.1%) patients. Conclusions. Various vascular and nonvascular diseases may mimic deep venous thrombosis, and that is why US should be used whenever possible to avoid unnecessary anticoagulant therapy. .

Abstract Abstract 5256 BACKGROUND: Deep venous thrombosis (DVT) is multi-causal disease associated to a high morbi-mortality due to complications as pulmonary embolism and post-flebitic syndrome. The incidence is about 20 to 30%, and 25% of the patients will present recurrence in 5 years. The identification of new risk factors is important in clinical practice to prevent new thrombotic events. The role of the platelets on DVT is still not well defined. AIM: The objective of this study was to analyze the hole proteins profile of platelets obtained from DVT patients and compare to the same matherial derived from healthy controls. PATIENTS: peripheral blood samples were collected from 3 spontaneous DVT patients and from 1 sibling and 1 neighbor for each patient in order to minimize the genetic and environmental interferences. These patients presented spontaneous and recurrent episodes of lower limbs proximal DVT and all of them mentioned a familiar history of coagulation disorders. METHODS: the platelets were washed, lysed, and the proteins were alkylated, reduced, precipitated with acetone and hydrolyzed by trypsin. 100mg of peptides were then separated by hydrophobicity using HPLC, and 8 fractions were obtained and directed to the LTQ-Orbitrap mass spectrometer. The proteins search was performed by Sorcerer-SEQUEST. RESULTS: We identified 5 proteins that were present on patients and absent in all the controls: Apolipoprotein A1 Binding-Protein, Coatomer (z1 sub-unit), Estradiol 11–17-b Dehydrogenase, Leucotriene A-4 Hydrolase and Sorbitol Dehydrogenase. Western-Blotting was performed with specific antibodies and validated the results. CONCLUSIONS: with this study it was possible to identify proteins up to date non-related to the physiopathology of DVT, that could be involved with metabolic and inflammatory processes. Disclosures: No relevant conflicts of interest to declare.

Background Although the role of incompetent perforating veins (IPV) in chronic venous insufficiency remains controversial, they are often treated by surgical or by minimal invasive techniques. Objectives To describe the procedure of radiofrequency ablation (RFA) of IPV and to evaluate its short-term effectiveness and safety. Methods In a clinical pilot study, 14 IPV in 12 patients were treated with a radiofrequency stylet. After three months, ultrasound (US) examination was used to assess anatomical success rate and exclude deep venous thrombosis. Also, self-reported side-effects were investigated. Results Of the 14 treated IPV, nine (64%) were obliterated on US examination and the others showed remaining reflux. Two patients reported localized paresthesia, but no deep venous thrombosis was recorded. Conclusion RFA of IPV may be a promising procedure, but patient and incompetent perforator vein selection is important and further standardization of the procedure is required. Comparative clinical trials between RFA and other therapies are warranted.
