Severe postthrombotic syndrome is associated with characteristic sonographic pattern of the residual thrombosis.

Postthrombotic syndrome (PTS) may affect 50% of patients with deep venous thrombosis, 5-10% of them may present severe manifestations. The causes for PTS development and severity have not been well established. This study evaluated whether PTS may be associated with the presence, and echogenicity, of the residual vein thrombosis (RVT).

CD144, CD146 and VEGFR-2 properly identify circulating endothelial cell.

Unlabelled: Studies evaluating circulating endothelial cells by flow cytometry are faced by a lack of consensus about the best combination of monoclonal antibodies to be used. The rarity of these cells in peripheral blood, which represent 0.01% of mononuclear cells, drastically increases this challenge.

Circulating progenitor and mature endothelial cells in deep vein thrombosis.

Introduction: Mature circulating endothelial cells (CEC) and circulating endothelial progenitor cells (EPC) have been described in several conditions associated with endothelial injury. Their role in deep vein thrombosis (DVT) has not been previously evaluated.

Patients And Methods: In this pilot study we evaluated the time course of CEC and EPC release after vena cava experimental DVT in mice, using the FeCl3 model.

Increased ADAMTS13 activity in patients with venous thromboembolism.

Increased levels of inflammatory markers and clotting factors have been related to the pathogenesis and prognosis of venous thromboembolism. In particular, the imbalance between VWF and ADAMTS13 has been described in patients with arterial thrombosis. In this study, 77 patients with previous VTE and 77 matched controls were selected for the evaluation of the inflammatory markers, FVW, ADAMTS 13 and D-dimer.

Inflammatory, immune and lipid transportation proteins are differentially expressed in spontaneous and proximal deep vein thrombosis patients.

Introduction: Deep vein thrombosis (DVT) is a multi-causal disease associated with high morbidity and mortality due to complications, and 25% of patients present recurrence within 5 years. The identification of factors involved with DVT can help in the management of patients, prevention of recurrence and in the development of new therapies. The evaluation of plasma components using proteomics potentially provides a window into the individual's state of health.

Diagnosis of Scott syndrome in patient with bleeding disorder of unknown cause.

Scott syndrome is a rare bleeding disorder due to an impaired exposure of phosphatidilserine on the platelet membrane, compromising the platelet procoagulant activity, thrombin generation and, thus, the clot formation. We report a case of a 17-year-old female adolescent with bleeding episodes of unknown cause. She had normal coagulation, but altered platelet aggregation under arteriolar flow, indicating platelet dysfunction.

Dual gene transfer of fibroblast growth factor-2 and platelet derived growth factor-BB using plasmid deoxyribonucleic acid promotes effective angiogenesis and arteriogenesis in a rodent model of hindlimb ischemia.

The protein infusion of basic fibroblast growth factor-2 (FGF-2) and platelet derived growth factor-BB (PDGF-BB) have been shown to promote the formation of a stable and functional vascular network in small and large animal models of ischemia. Here, we sought to determine whether a similar effect could be obtained using a gene-therapy-based strategy with nonviral vectors. Rats underwent a surgical procedure to create hindlimb ischemia and were injected with a combination of plasmids that expressed FGF-2 and PDGF-BB.
