Interventions in Dialysis Grafts

摘要: Thrombosis occurs roughly 10 times more frequently in dialysis grafts compared to autogenous fistulas. AVGs is often the result of an underlying hemodynamically significant stenosis. The site stenosis can be determined by physical examination where inflow and outflow stenoses identified. Key points evaluate are location type graft, presence pseudoaneurysms, dilated collateral veins particularly on chest, pulsatility or thrill flow within graft itself. Ideally, there a transition from arterial anastomosis towards end graft. If throughout one suspects A lack palpation commonly indicates problem. Lack any possible thrombosis. An in-room ultrasound allows quick access determination problem, thereby allowing for preplanning interventions. Clinical also single most reliable indicator procedural success following intervention, with restoration distal portion associated higher patency rates [1].
