Application of Angioscopy for Diagnosis and Treatment of Venous Thromboembolism

摘要

Although compression ultrasonography(US) or angiography has been widely used for diagnosis of deep venous thrombosis(DVT), characteristics of thrombus Recently, US elastography has been developed to evaluate hardness and elasticity of tissue. To evaluate thrombus, angioscopy has been shown to be useful because it can provide macroscopic direct image of trhombus 1,2. However, its use for DVT has been limited because of risk for perforation of fragile veins. Recently,using new balloon guiding catheter, angioscopy can be safely performed for visualiztion of venous thrombus. The risk factors for vascular diseases such as, obesity, smoking, and hyperlipidemia, have also been considered as risk factors for VTE 3,4. The true association between VTE and the risk factors for atherosclerosis, however, has not been clearly reported. In this study, we evaluated usefulness of angioscopy (AS) and US elastography for diagnosis of VTE.. The association between VTE and vascular risk factors was also evaluated.
