Abstract:
Radial-cephalic arteriovenous fistula (RCAVF) is considered the first choice for hemodialysis vascular access because of its high patency rate and less complications.But up to 50％ of the fistula can not mature.This is mainly due to persistent low blood flow or difficulty in cannulation can not lead to adequate hemodialysis.Inflow or outflow stenosis,anastomotic stenosis,exceedingly deep location of the vein,flow diversion into accessory veins are the common causes of impaired maturation.In addition,thrombosis is a common of stenosis.Preoperative assessment by physical examination and ultrasound examination of blood vessels,select the appropriate blood vessels for the fistula is of great significance.Choose the appropriate treatment for the cause of maturation disorders.Postoperative aspirin is widely used to prevent thrombosis and reduce the occurrence of stenosis;Surgery has the advantage of bypassing the damaged area but creating a new stoma;in recent years,endovascular technique because of its characteristics of minimally invasive in most of the time is the first choice.In this paper,the definition,etiology,diagnosis and treatment of fistula maturation disorder are reviewed.
