Epidemiology of acute deep vein thrombosis 总被引:6,自引:0,他引:6
Although the factors leading to venous thrombosis have been known for over a century, Virchow's initial model of thrombosis has been extensively refined. Activated coagulation is now recognized to be of primary importance in venous thrombogenesis; the concept of venous injury has been expanded to include molecular changes in the endothelium; and stasis has been redefined as a largely permissive factor. Furthermore, it is now clear that venous thrombi undergo a dynamic evolution beginning early after their formation. The natural history of acute deep venous thrombosis (DVT) is a balance between recurrent thrombotic events and processes that restore the venous lumen, both of which have important implications for the development of complications. Although pulmonary embolism (PE) is clearly the most life threatening complication of acute DVT, the long term socio-economic consequences of the post thrombotic syndrome (PTS) have perhaps been underemphasized in clinical trials. The development of post-thrombotic manifestations is related to both residual venous obstruction and valvular incompetence. Recognition of the factors contributing to a poor outcome, including recurrent thrombotic events, the rate of recanalization, the global extent of venous reflux, and the anatomic distribution of reflux and obstruction is important, as there may be therapeutic alternatives to alter the natural history of acute DVT. The treatment alternatives will continue to expand with the introduction of new therapeutic drugs, for both systemic and catheter-directed therapy, and mechanical thrombectomy devices. The primary care physician is challenged with the task of correctly evaluating deep vein thrombosis and providing his patient with access to the most clinically appropriate, and cost-effective, diagnostic and management options available. This article will review the epidemiology of DVT, its risk factors and major complications. 相似文献

The case of a 24-year-old female professional, long-distance runner who presented with acute proximal posterior thigh pain is reported. History and clinical findings were consistent with acute hamstring strain but MRI demonstrated circumflex femoral vein thrombosis. This is the first case of proximal posterior thigh pain caused by circumflex femoral vein thrombosis reported in the literature. Doctors dealing with sports injuries should be aware of this clinical entity that mimics hamstring strain. 相似文献

In previous studies, (99m)Tc-recombinant tissue plasminogen activator (rt-PA) imaging has had a high sensitivity and specificity for the detection of deep vein thrombosis (DVT). In this technique, the plasminogen activation site of rt-PA undergoes inactivation but fibrin binding is retained. Uptake of (99m)Tc-rt-PA into DVT relies on binding of C-terminal lysine residues on fibrin. It is postulated that as the thrombus ages, fewer fibrin sites are available for (99m)Tc-rt-PA and that there should be a progressive decrease in (99m)Tc-rt-PA uptake in old thrombi as compared with fresh thrombi. The ability to differentiate fresh from old thrombus would have significant clinical implications in the objective diagnosis of recurrent DVT. Our aim was to examine the relative uptake of (99m)Tc-rt-PA in acute DVT over the first 30 d after diagnosis. METHODS: Seventy-four patients with acute symptomatic DVT were entered into the study. Patients underwent ultrasound and (99m)Tc-rt-PA imaging on days 1, 7, and 30. RESULTS: Residual thrombus was detected by ultrasonography in 46 (84%) of 55 patients on day 7 and in 29 (66%) of 44 patients on day 30. Of the persisting thrombi on day 7, 72% (33/46) showed (99m)Tc-rt-PA uptake. Of the persisting thrombi on day 30, 0% (0/29) showed (99m)Tc-rt-PA uptake. CONCLUSION: Uptake of (99m)Tc-rt-PA into DVT was absent 30 d after diagnosis. This finding suggests that this imaging technique can distinguish fresh from old thrombus. 相似文献
