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.
经颈静脉通路是上肢透析动静脉内瘘和移植物血管内介入的一种替代方法。对于直接手臂通路解剖结构不佳的患者,推荐采用经颈静脉通路。在进行干预前,对动静脉通路进行超声评估至关重要,评估内容包括流入动脉和流出静脉的直径、动静脉吻合口以及整个流出静脉,尤其要查看潜在的问题区域。需要评估同侧颈内静脉的通畅情况。如果同侧颈内静脉通畅得到确认,就可用于通路建立。使用反弯导管和导丝获得进入流出静脉的逆行通路。在某些情况下,需要穿刺流出静脉并使用圈套器将导管系统引入流出静脉。文中描述了干预技术。在超过95%的病例中能够成功进入流出静脉。该技术有助于内瘘成熟、血栓清除程序以及动静脉内瘘和移植物的维护。如果干预不成功,经颈静脉通路提供了放置透析导管进行临时或长期透析的可能性。
