1 Vascular access for hemodialysis
Steve J. Schwab  Kidney International  Volume 55, Issue 5, Pages (May 1999) DOI: /j x Copyright © 1999 International Society of Nephrology Terms and Conditions

2 Figure 1 Intravascular ultrasound of fibromuscular hyperplasia in brachial vein at the vein graft anastomosis. Sphere in center of vein is the head of the ultrasound catheter. Kidney International  , DOI: ( /j x) Copyright © 1999 International Society of Nephrology Terms and Conditions

3 Figure 2a Radiograph of outflow stenosis at vein graft anastomosis in an AV graft before (A) and after (B), opposite page, correction with angioplasty. A. White arrowhead represents location of occluding blood pressure cuff. White arrow shows stenosis at vein graft anastomosis. Black arrow represents AV graft. Curved white arrow indicates proximal native vein. Kidney International  , DOI: ( /j x) Copyright © 1999 International Society of Nephrology Terms and Conditions

4 Figure 2b White arrow shows stenosis post angioplasty demonstrating restored venous flow. (From Schwab SJ, Saeed M, Sussman SK, McCann RL, Stickel DL: Transluminal angioplasty of venous stenoses in polytetranfluoroethylene vascular access grafts. Kidney Int 32:395–398, 1987.)

5 Figure 3 Primary unassisted patency of AV fistulas and AV grafts. Solid line represents AV fistula patency. Dashed line represents AV graft patency. AV fistula patency excludes fistulas that did not mature sufficiently to allow initial cannulation. Graph derived from summed data analysis from the Vascular Access DOQI7. Primary patency reflects patency from initial cannulation to first intervention. First intervention could reflect thrombosis, removal, angioplasty, or surgical revision.

6 Figure 4 Cumulative patency of AV fistulas and AV grafts. Solid line represents AV fistula patency. Dashed line represents AV graft patency. AV fistula patency excludes AV fistulas that did not mature sufficiently to allow initial cannulation. Graph derived from summed data analysis from the Vascular Access DOQI7. Cumulative patency reflects patency from initial cannulation to abandonment or removal of access. AV graft intervention (procedure) rate > 3 × AV fistula intervention rate.

7 Figure 5 Cumulative patency of AV fistulas and AV grafts with prospective monitoring and intervention. Solid line represents AV fistula patency. Dashed line represents AV graft patency. AV fistula patency excludes AV fistulas that did not mature sufficiently to allow initial cannulation. Cumulative patency reflects patency from initial cannulation to abandonment or removal of access. AV graft intervention (procedure) rate > 6 × AV fistula intervention rate.

8 Figure 6 Central vein stenosis recurrence rate following angioplasty or angioplasty and use of a wall stent. (From Ref. 52.). Kidney International  , DOI: ( /j x) Copyright © 1999 International Society of Nephrology Terms and Conditions
