简要总结
This study will determine whether upper arm vessels increase in size following forearm loop arteriovenous graft placement and the timing of these changes.
详细描述
The purpose of this study is to determine whether upper arm vessels increase in size following forearm loop arteriovenous graft placement, and if they do, characterize the timing of these changes.
