AbstractThrombophilia refers to the increased tendency to form blood clots (thrombosis), which is a major cause of morbidity and mortality. Thrombosis is associated with various chronic conditions such as cancer, diabetes, renal disorders, and cardiovascular disease. The incidence and associated complications of thrombosis are likely to increase significantly in the next few decades because of aging populations. Regular exercise has been proposed to decrease the risk of developing thrombosis, although there are inconsistent data from studies investigating its effects, with reports of both increased and decreased thrombotic risk across a variety of subject cohorts. Confounders such as age, gender, hormonal variations, physical activity, underlying disease and treatment, and body composition also contribute to the difficulty in assessing and defining the precise effects of exercise in preventing thrombotic events. However, there is evidence suggesting that physical activity is beneficial for reducing thrombotic risk in younger individuals and those with chronic conditions. This article aims to summarize the known risk factors for thrombosis and briefly review the benefits of exercise in the general population. Furthermore, this article highlights the additional factors in a cohort of individuals that would (at first) appear unlikely to be at risk of thrombosis—elite athletes. 相似文献

Thrombosis at mountain altitudes 总被引:2,自引:0,他引:2
Victims of high-altitude pulmonary edema often have clots obstructing the pulmonary vessels. This, together with an apparent high incidence of thrombophlebitis and cerebral emboli at altitude suggests that mountain travel may predispose to hypercoagulability. A critical analysis of the available data suggests that, although thrombosis may be a late event complicating various forms of mountain sickness, the laboratory techniques of characterizing hypercoagulability are not sufficient to define and characterize the mechanism. 相似文献

Among 3,307 consecutive patients (3,556 legs) with deep venous thrombosis, 54 (1.5%) showed an isolated thrombus of the popliteal
vein on phlebography. The majority of those had a history of “effort” or long lasting flexion during air or bus travel. Forty-four
percent suffered from pulmonary embolism as the first sign of deep venous thrombosis. Functional phlebography demonstrated
the primary site of thrombosis at folds forming in the vein wall at flexion. In order to further elucidate the pathogenetic
mechanism, 158 popliteal veins were examined phlebographically in different functional states revealing age-related characteristic
wall patterns of rings and folds in flexion causing transient impairment of flow. Complementary morphological studies of 120
popliteal veins during autopsy showed a transverse rippling of the vein wall caused by intimal fibrosis and partial atrophy
of the media corresponding to the phlebographic findings. It is concluded that microtrauma during effort in combination with
impaired venous backflow and fibrotic transformation of the venous wall can lead to thrombus formation in the popliteal vein. 相似文献

Radionuclides have been used in the evaluation of intravascular thrombosis for several years. The most widely accepted nonimaging technique is I-125 labeled fibrinogen. It is commonly used for patients who have a high probability of developing a thrombus (e.g., those undergoing surgery). Other techniques are emerging as having value in thrombosis detection. These techniques include radionuclide venography and clot localization scanning techniques utilizing the affinity of clot for small radiolabeled particles, as well as imaging techniques using I-131 labeled fibrinogen. More recently, a number of the above-mentioned techniques have been applied to patient problems. The FDA ban on commercial radiolabeled fibrinogen in the United States has promoted the development of alternative techniques and the use of autologous fibrinogen. A number of other techniques for thrombosis detection have also been explored on a more experimental basis. They include the use of thrombolytic agents such as streptokinase, urokinase, and white blood cells, as well as platelets. The common lung or pulmonary perfusion scan using macroaggregates of albumin or microspheres radiolabeled also gives information as to the presence of thrombosis of embolus within the pulmonary arteries, by showing the effect upon the perfusion pattern. This review will explore in detail the principles, as well as the present and prospective usefulness of the techniques currently available. 相似文献

Purpose: To report on the efficacy of fixing fresh venous thrombus to the venous wall by stent placement.
Methods: Seven patients underwent stenting to treat acute venous thrombosis. In two patients, the hemodialysis fistula was thrombosed
with the thrombus extending into the brachial veins. In three patients, the hemodialysis fistula was patent but massive swelling
of the ipsilateral arm was caused by proximal venous thrombosis. Two patients presented with iliac venous thrombosis within
stented pelvic veins. Stent placement was preceded by other mechanical thrombectomy methods in all cases.
Results: Attachment of thrombus to the venous wall was successful in all cases treated. Acute rethrombosis did not occur. Follow-up
patency in dialysis patients was 7.2 ± 2.1 months. One patient had rethrombosis of the dialysis graft 3 months after primary
treatment. Three patients developed restenosis within a mean period of 7.7 months. One shunt remained patent for 10 months
with no event of reobstruction during follow-up. In both patients with iliac stent placement, the vein remained patent over
a follow-up period of 8 and 12 months respectively.
Conclusion: Stenting fresh venous thrombus can achieve immediate venous patency. It may be used as an alternative approach when all other
percutaneous methods fail. Frequent restenosis within stented veins limits its use to very selected cases.
