AI Article Synopsis
- Three aging hemodialysis bypass shunts (averaging 44 months old) experienced issues like pseudoaneurysms and thrombosis and were treated with covered stents.
- One graft was ligated due to an infection but still retains a functional covered stent after additional surgery.
- Follow-ups show that the other two grafts remain patently functional, allowing for routine dialysis punctures, indicating that covered stents can extend the life of failing bypass grafts in elderly patients.
Article Abstract
Three aging failing hemodialysis polytetrafluoroethylene bypass shunts, average age 44 months, previously percutaneously revised with balloon angioplasty, presented with pseudoaneurysms and recurrent thrombosis. All were treated with percutaneous covered stent placement within their affected limbs. One graft was ligated 1 month after treatment for infected overlying skin ulcer, though this graft was subsequently surgically revised with interposition graft and the covered stent portion remains functional at 19 month follow-up. The 18- and 13- month follow-up of the remaining 2 patients shows that the covered stents remained patent and they are functional and being successfully and routinely punctured for dialysis. In this elderly population, the use of covered stents may prolong the functional life of failing hemodialysis bypass grafts, reducing the number of percutaneous and surgical interventions and further sparing other vascular access sites.
