- W2380948041 abstract "Objective To analyze and evaluate diagnostic value of superior vena cava syndrome (SVCS) with two-dimensional and Doppler echocardiography.Methods Twenty-one patients with SVCS and 20 healthy volunteers were studied by echocardiography from the right supraclavicular view and the apical 5-chamber plane.Results Fifteen patients of outer-pressing type,5 patients of intra-cavity type and 1 patient of other type were found with ultrasonography.The diameter of the superior vena cava in outer-pressing type was thinner than that of normal control [( 6.7± 7.4)mm vs ( 11.4± 2.1)mm,P 0.001],and the forward flow velocities were higher than those of normal contrast [( 128.0± 40.9)cm/s vs ( 50.3± 8.2)cm/s,P 0.01] in SVCS.Superior vena cava in 2 patients with serious stenosis showed low flow velocities.Five patients with intra-cavity type presented thrombus echo and lower flow velocities in superior vena cava [( 16.4± 6.9)cm/s vs ( 50.3± 8.2)cm/s,P 0.01].Conclusions Echocardiography plays an important role in the diagnosis of SVCS.It can not only assess damaged location and degree,but also provide etiological diagnosis of SVCS." @default.
