Resection of puncture site necrosis over an arteriovenous fistula: Endoclamp use for preservation of cannulation sites:
2018
Skin
necrosisoverlying an
arteriovenous fistulaat the cannulation site is a common and potentially life-threatening problem, often associated with underlying aneurysm formation.
Arteriovenous fistula-skin
necrosisgenerally requires resection of surrounding skin margins and the underlying aneurysmal vessel wall, allowing repair with healthy tissue of the
arteriovenous fistulain addition to closure of soft tissue and skin. In patients with insufficient
fistulalength, salvage of these
arteriovenous fistulasmay result in difficult or insurmountable cannulation issues leading to attempts at one-needle cannulation dialysis or, most often, catheter placement. Pre-existing stents or extensive calcification may add to the technical challenge of gaining proximal and/or distal control. We describe our technique for dealing with such
arteriovenous fistula-skin
necrosislesions utilizing endo-occlusion with an angioplasty balloon for vascular control, allowing a limited incision and tissue resection with preserv...
