RR7. Treatment Strategies of Arterial Steal After Arterio-Venous (AV) Access

Understanding strategies for the treatment of ischemic steal syndrome after hemodialysis access.

The recently published guidelines of the National Kidney Foundation-Dialysis Outcome Quality Initiative have focused on improving patient outcomes and survival by providing recommendations for optimal clinical practice. These guidelines firmly endorse the establishment of autogenous hemodialysis access and recommend a 40% to 50% prevalence of autogenous fistulas among all hemodialysis patients....

Transition to collateral flow after arterial occlusion predisposes to cerebral venous steal.

BACKGROUND AND PURPOSE Stroke-related tissue pressure increase in the core and penumbra determines regional cerebral perfusion pressure (rCPP) defined as a difference between local inflow pressure and venous or tissue pressure, whichever is higher. We previously showed that venous pressure reduction below the pressure in the core causes blood flow diversion-cerebral venous steal. Now we investi...

Pulmonary arterio-venous fistula.

As would be expected, the lesion is recognized in young to early middle life. The patient tends to be frail rather than robust, though there are exceptions to this, and there is no physical retardation. Clubbing of the fingers is frequently present, and telangiectases or hemangiomata may be present in the skin or mucous membranes. The most common presenting symptoms are cyanosis, which sometime...
