The purpose of this study was to investigate the relationship between the distribution of turbulence intensity and the localization of stenoses inside the venous anastomosis of arteriovenous (A-V) grafts. Turbulent flow measurements were conducted inside an upscaled end-to-side graft model under pulsatile flow condition. The pulsatile flow waveforms had maximum, minimum and mean Reynolds number...

We will show the 17 years’ experience in Toho University. Methods: We had 344 cases for 17 years. The average age was 51.4 years. Chief complains were curvature, palpable fibrosis, pain, ED etc. The angle of curvature was 0 to 90 degrees. Ab...

over a seven year period from 1982 to 1989,3337 conduits were created in 3137 patients with end stage renal disease (esrd) as access for chronic dialysis. these included 2690 side-to-side arteriovenous fistulae (a vf), 168 end-to-side a vfs, 10 autogenous vein grafts, 51 homogenous frozen vein grafts, 109 polytetrafluoroethylene (ptfe) grafts, 209 emergency external arteriovenous shunts, three ...

OBJECTIVE Inflammation appears intricately linked to vein graft arterialization. We have previously shown that tumor necrosis factor (TNF) receptor-1 (TNFR1, p55) signaling augments vein graft neointimal hyperplasia (NH) and remodeling through its effects on vascular smooth muscle cells (SMCs). In this study we examined the role of TNFR2 (p75) signaling in vein graft arterialization. METHODS ...

A hemodialysis patient presented with an abnormal CXR (Panel A) 13 years after coronary artery bypass grafting and a CT scan was performed (Panel B). Maximal-intensity-projection (Panel C) and 3D reconstructions (Panel D) revealed a large aneurysm, containing thrombus, arising from the vein graft to his right coronary artery (Fig. 1). Fig. 1. (A) Chest radiograph (PA) showing the abnormal right...

Matrix metalloproteinases (MMPs) play key roles in vascular remodeling. We characterized the role of inflammatory mediators and extracellular signal-regulated kinases (ERKs) in the control of arterialized vein graft expression of MMP-9, MMP-2, and membrane-type 1-MMP (MT1-MMP) and of the tissue inhibitor of metalloproteinases-2 (TIMP-2). For this purpose we used a canine model of jugular vein t...
