Development of new implant vascular access

Vascular Access and New Trends

Snare-assisted vascular access: a new technique.

Access to the central circulation can be difficult in small infants, particularly when normal anatomic landmarks have been altered. We describe a new technique that utilizes any existing central catheter to establish additional sites of vascular access. A 4 Fr end hole catheter is advanced under fluoroscopic guidance to the desired site of new vascular access. A 10-mm Amplatz snare catheter is ...

New Insights into Dialysis Vascular Access: Introduction.

Optimizing vascular access outcomes continues to pose a tremendous challenge to nephrologists, surgeons, and radiologists who provide medical care to patients on hemodialysis. There is a huge discrepancy between the optimal vascular access outcome proposed by national guidelines (1) and the reality. Thus, for example, whereas the guidelines suggest that most patients should initiate hemodialysi...

the effects of new design of access hole on porcelain fracture resistance of implant-supported crowns

statement of the problem: one disadvantage of cement-retained crowns is the lack of predictable irretrievability. this problem can be overcome through designing a screw access hole in the metal substructure of cement-retained restoration and using porcelain stain to define this area. purpose: this study aimed to evaluate the influence of existence of screw access hole on porcelain fracture resi...

VASCULAR ACCESS FOR HEMODIALYSIS: OUR EXPERIENCE WITH 3337 CASES

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, t...
