BACKGROUND: Upper arm swelling and @entity101 at arteriovenous fistula sites, and insufficiency of hemodialysis are induced by central @entity455 in chronic hemodialysis @entity1 . Percutaneous transluminal angioplasty ( @entity865 ) for central @entity455 is first-choice treatment. Cardiac function can be evaluated by measuring the acute increase in venous return volume after @entity865 . METHODS: We studied 6 cases of successful @entity865 for central venous stenotic or occluded lesions, and evaluated cardiac function by Swan-Ganz (SG) catheter and ultrasound echocardiography (UCG) at pre-, post- @entity865 , and on the following day. RESULTS: Ejection fraction (EF) in 6 cases was 71.0    5.5% on UCG. Two cases of subclavian @entity1211 , one case of subclavian @entity432 , and three cases of @entity432 were enrolled. The reference diameter (RD) was 10.2    4.9 mm, % @entity850 (%DS) was 92.2    12.2% at pre- @entity865 , and %DS at post- @entity865 was 21.7    20.7%. There were no significant differences in pulmonary capillary-wedge, pulmonary artery, and right ventricular end-diastolic pressure in SG at pre- and post- @entity865 . The pressure of right atrium (RA) and cardiac output (CO) were significantly increased by @entity865 (RA pressure at pre-/post- @entity865 , 9.7    2.9/11.7    3.6 mmHg, p<0.05, CO at pre-/post- @entity865 5.09    2.07/5.45    2.25 l/min, p<0.05). There were no significant differences in serial EF, left atrial and left ventricular diameters on UCG. However, the short-diameter of right ventricle (RV) and RA were significantly increased at post- @entity865 and recovered on the following day (RV short-diameter at pre-/post-/following-day @entity865 , 26.7    3.5/32.5    1.9/29.1    1.7 mm, p<0.05; RA short-diameter at pre-/post-/following-day @entity865 , 30.2    4.2/36.3    2.4/32.1    3.6mm, p<0.05). CONCLUSIONS: @entity1284 after @entity865 for central venous stenotic or occluded lesions in chronic hemodialysis @entity1 resulted in increased RA and RV diameters. These changes were transient and completely recovered by the following day. @entity865 for central @entity455 in @entity1 with normal EF can be performed without clinical cardiac problems.
