BACKGROUND Regular monitoring of dialysis grafts is recommended, but the value of dialysis graft blood flow monitoring and venous pressures in predicting subsequent outcomes are controversial. METHODS Over a period of one month, we performed simultaneous flow and venous pressure monitoring in 71 dialysis patients with polytetrafluoroethylene (PTFE) grafts. These patients were prospectively fo...

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 ...

Scientific literature describes autogenous bone as the gold standard among graft materials for alveolar reconstructive procedures. Alveolar ridge augmentation has been clinically achieved with different forms of autogenous bone, including autogenous cortical bone particulate (ACBP). However, few histologic studies demonstrating the biologic potential and healing dynamics following the use of AC...

In patients highly suspected of developing steal syndrome, the subscapular artery may be a good supplier for functional prosthetic arteriovenous access, as well as a good solution for the prevention of steal syndrome. A 51-year-old woman was preparing to have a loop shaped polytetrafluoroethylene (PTFE) graft placed at the left upper extremity. The diameter of subscapular the artery was 3 mm. A...

arteriovenous fistulae traditionally have been placed in the upper extremity. experience with groin hemodialysis access has been discouraging because of high infection rates and associated limb amputation. the aim of this study was to determine infection rates, patency rates, and possible predictive factors for prosthetic thigh angioaccess outcomes in our hemodialysis patient population. a pros...

The types of fistulae used and their complication rates are important for the hemodialysis patients. We aimed to compare retrospectively the primary and secondary patency rates and complications of upper extremity arteriovenous fistulae. Between 1984 and 2005, a total of 1,233 upper extremity arteriovenous fistulae were created in 920 patients. The mean age was 42 +/- 21 years. The fistulae wer...

This clinical study was performed to investigate the patency rate of endothelial cell-seeded small-diameter expanded polytetrafluoroethylene grafts during coronary artery bypass surgery. Between September 1995 and December 1998, 14 patients (median age: 71 years, range: 61-79 years) received 21 endothelial cell-seeded small-diameter grafts. In all, 43% of the performed implantations were reoper...
