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 ...

True aneurysm formation in infrainguinal autologous vein grafts is rare. The authors report a case of a patient presenting with extensive aneurysmal degeneration of a femoropopliteal bypass vein graft 13 years after the original operation and 8 years after graft revision and thrombolysis for acute occlusion. Over a 2-year period, the vein graft aneurysm expanded from 2.7 to 4.5 cm maximal diame...

INTRODUCTION: The removal of a global mean signal has been widely adopted in the processing of resting-state fMRI studies [1]. However, there has been recent controversy regarding its usage, since negative correlations with a seed ROI are mathematically mandated after regressing out the whole brain global mean signal (denoted as ‘whole-gs’) [2]. Here we introduce an alternative “global” signal ...
