Although several acquired and genetic risk factors are known, about half that develop a thromboembolic event have no identifiable risk factor. Control of the inflammatory process is thought to be the key factor in risk reduction for thrombotic events. Prophylactic use of anticoagulants is not universally recommended, but possible use should be reviewed in an individual patient after evaluation of the risks, such as hemorrhage, compared to potential benefits. Particular consideration should be given if there has been a prior thrombotic event, if hospitalization will require surgery, or if an underlying coagulation disorder is present.展开更多

Although the affected blood vessel may be arterial or venous one and caused either by inflammation or degenerate changes, they share common symptoms and signs, such as blood stasis, ischemia, thrombosis, ecchymosis, swelling, constriction or obliteration of blood vessels due to circulatory impairment. Since they share common characteristics, the treating principles and methods will be discussed as follows.展开更多

We report a case of a patient who had visual loss probably associated with interferon therapy. Chronic hepatitis C virus infection （genotype la） was diagnosed in a 33-year old asymptomatic man. His past medical history was unremarkable and previous routine ophthalmologic check-up was normal. Pegylated interferon alpha and ribavirin were started. Three weeks later he reported painless reduction of vision. Ophthalmologic examination showed extensive intraretinal hemorrhages and cottonwool spots, associated with inferior branch retinal vein thrombosis. Antiviral therapy was immediately discontinued, but one year later he persists with severely decreased visual acuity. This case illustrates the possibility of unpredictable and severe complications during pegylated interferon therapy.展开更多

Methods: 105 consecutive subjects diagnosed with limb deep venous thrombosis (DVT) by lower limb phlebography underwent non-selective pulmonary angiography. Results: 52.38% patients were diagnosed with pulmonary embolism, 21.9% with inferior vena cava thromboembolism, and 9.52% with pulmonary embolism combined with inferior vena cava thrombosis. Images obtained by non-selective pulmonary angiography had a good correlation with selective pulmonary angiography. Conclusion: The non-selective pulmonary angiography was a simplified, efficient and safe method for pulmonary embolism diagnosis. Large clinical trials are still needed to further evaluate the accuracy and safety of the non-selective method.展开更多
