Abstract/OtherAbstract:
The purpose of this study was to evaluate the value of complex hemodialysis access procedures among patients with central venous obstruction who were running out of access sites. Between September 2002 and December 2003 we performed a total of 640 new hemodialysis access procedures in 3 renal units. Ten of these patients presented central vein stenosis or obstruction and were not suitable for peritoneal dialysis. Each of the 10 patients had 3 or 4 previous failed access procedures and numerous infected central lines and their dialysis catheters were not functioning adequately. Nine patients presented with a severely stenosed or occluded superior vena cava and 1 had both subclavian veins occluded. Three patients were diabetics, 2 were obese and 6 had hypertension. We performed 12 procedures on these 10 patients. Saphenous veins were used 6 times, twice as a loop to the femoral artery and 4 times as a transposition to the popliteal artery above the knee. Femoral vein transposition to the popliteal artery was carried out in 2 cases. We performed 3 axillary artery to popliteal vein polytetrafluoroethylene (PTFE) bypasses, 1 on an obese woman who had no saphenous vein and was not suitable for a femoral vein transposition, 1 on a diabetic woman whose saphenous vein loop clotted after 5 months and 1 on a female patient with severe peripheral vascular disease. The patient with bilateral subclavian vein occlusion had a brachial artery to internal jugular vein PTFE graft. The PTFE graft to the jugular vein has been patent and regularly needled with a follow-up of 4 months. Four saphenous vein fistulae were regularly used for dialysis; 2 were never used. Five saphenous fistulae clotted after an average life span of 4 months (range 3 weeks-9 months) and 1 is still patent and in use (5 months). Both femoral vein transpositions have been patent and have been needled 3 times a week with a follow-up of 10 and 4 months; one had to be revised surgically after 9 months. Of the 3 axillary artery to popliteal vein grafts, 1 had to be tied off after a week because of severe steal syndrome and 2 have been patent (20 months follow-up) and have been needled regularly ever since. Seventy percent of these patients have been dialyzed line-free through their fistula despite severe central vein stenosis or obstruction for periods of 9-18 months when this review was undertaken. Although the follow-up needs to be longer, we discuss the surgical, radiologic, and dialysis features of these patients and propose a management pathway for central vein stenosis or occlusion.
