Case study: Dialyaia graft outlet surgical revision

5/5/2014

Dialysis graft outelt stricture is one of the most frequent complication/situation that a dialysis surgeon faces in his dailiy practice. To cope with the stenotic lesion, the oldest way, probably the most reliable, is to do surgical revision.

There are two ways of surgical revision of the graft outlet. Here shows the so called" patch angioplasty" method. If the stenotic lesion is a focal or short lesion, we can just longitudinally incise teh graft outlet, and apply a ePTFE patch (which is the same material of the graft) to augment the outelt space. after the operation, the graft outlet should be widely open.

The operation usually takes around 1 hour to perform. ofcourse, reoperation sometimes will be troublesome. However, most of the stenotic lesion can be fixed by patch angioplasty. Only if the lesion is too long, then we will try to fix the lesion using a jump graft.




Ofcourse nowadays most of the graft outelt stenotic lesion are first treated with angioplasty balloons/ stenting, which is less invasive. However, surgeon should always keep himself familiar with the open procedure. and once the PTA doesnt work, we still can provide a feasible choice of treatment instead of giving up the graft!
