Transjugular venous approach for endovascular intervention in upper-extremity dialysis access fistulae and grafts

A transjugular venous access is an alternative approach for endovascular intervention in upper-extremity dialysis arteriovenous fistulae and grafts. The transjugular access is recommended for patients who have an unfavorable anatomy for the direct arm access approach. Ultrasound evaluation of the arteriovenous access is essential before intervention and includes evaluation of the inflow artery and outflow vein diameters, arteriovenous anastomosis, and the entire outflow vein, specifically looking into potential problem areas. Patency of the ipsilateral internal jugular vein needs to be assessed. If patency of the ipsilateral internal jugular vein is confirmed, it can be used for access. Retrograde access into the outflow vein is obtained with a reverse-curve catheter and a Glidewire. In some cases, puncture of the outflow vein is necessary along with the use of snares to direct the catheter system into the outflow vein. The techniques for intervention are described. Successful access into the outflow vein is possible in >95% of cases. The technique is useful for fistula maturation, declotting procedure, and arteriovenous fistula and graft maintenance. If intervention is unsuccessful, the transjugular access offers the possibility of placement of a dialysis catheter for temporary or long-term dialysis.
