XXXX : an under-recognized complication of hemodialysis access.

@entity1 @entity1095 @entity6 @entity63 @entity16 @entity2690 @entity3949 @entity1897 @entity130
During the past 3 years six episodes of @entity63 ( @entity63 ) have been identified in five @entity1 as a complication of upper extremity dialysis grafts. All @entity1 had long-standing @entity2690 -dependent @entity6 , @entity1897 , and brachial artery graft origins, whereas 60% had @entity1095 . Five episodes occurred immediately after graft placement, whereas one was due to a graft-related thromboembolus. Diagnostic delay was common with initial findings attributed to anesthesia, positioning, or surgical @entity130 . Electrophysiologic studies showed underlying @entity3949 with @entity16 distal to the grafts. Digital pressure indices were reduced but there was no critical @entity63 . In three cases @entity63 was completely corrected with improvement in one. One @entity1 had proximal balloon angioplasty with no improvement and of the two untreated @entity1 , one improved slightly. @entity63 is a rare but disabling complication of dialysis access in @entity6 @entity1 . Its occurrence is unpredictable and diagnostic delay is common. Correction of @entity63 is indicated but usually does not improve the @entity16 . Prevention requires further research to more accurately characterize the @entity1 at risk.
