Arteriovenous shunt graft ulceration with sinus and graft epithelialization

Abstract

Arteriovenous fistula and grafts are used as access sites for patients with chronic kidney disease and are prone for complications. Stent grafts are used to treat access site complications. We report a rare and unusual finding of epithelialization of the sinus tract and the lumen of a polytetrafluoroethylene graft, following ulceration of the overlying skin.

First Reported Case of Neointimal Hyperplasia in the Midportion of a Polytetrafluoroethylene Dialysis Graft

“…These activated macrophages then produce cytokines, which cause smooth muscle cell proliferation and lead to venous intimal hyperplasia. 2 Most research on venous intimal hyperplasia has been dedicated to graft vein anastomosis sites and we can only extrapolate from previous findings and apply it to our own, as this is the first case of Fig. 1.…”
