Dialysis Access

Patients with renal failure require hemodialysis via an arteriovenous fistula or a temporary tunneled catheter.  AV fistula can be made with native vein or synthetic material such as Gore-Tex.  Proper surveillance during dialysis and maintenance can increase the longevity of the AV fistula/graft.  Tunneled dialysis catheters (permcath) can be a temporizing means of hemodialysis for those who require temporary dialysis or are awaiting AV fistula/graft maturity. 

In advanced patients who no longer have AV fistula/graft options, tunneled catheter is the last remaining option of hemodialysis.  Fistulograms (contrast study of fistula under fluoroscopic guidance) and insertion and change of tunneled catheters are performed with conscious sedation by an interventional radiologist in an outpatient setting.  Angioplasty balloons and stents are used to reopen or dilate narrowed portion of the fistula to increase the lifespan of the fistula.

For more information or questions please call Interventional Radiology at Rhode Island Medical Imaging at (401)-421-1924.

Posted: 04.02.18

As RIDOT replaces the Parkway Ramp Bridge in East Providence (see below for more information), they will need to close the I-195 West on-ramps from Veterans Memorial Parkway and Warren Avenue in East Providence beginning Wednesday, April 4. Get detour information here.

Traffic heading north on the Parkway will follow a detour using Lyon Avenue to Warren Avenue to Broadway. Local traffic on the Parkway north of Lyon Avenue can use Mauran Avenue (the last street before the Parkway on-ramp) to Burgess Avenue to reach Warren Avenue and the detour route to Broadway.

Those heading to destinations on the East Side of Providence may wish to follow Valley Street to North Brow Street to Massasoit Avenue to use the Henderson Bridge as an alternate detour. Motorists also may wish to use Pawtucket Avenue or the Wampanoag Trail to the East Shore Expressway for I-195 West access.

The bridge replacement will be completed in late fall, however work on the nearby Washington Bridge will extend its reopening until the end of 2019.
