Abstract

SILVEIRA, Diogo et al. Renal allograft anastomotic pseudoaneurysm presenting with acute renal failure: a case of surgical treatment with graft preservation. Angiol Cir Vasc [online]. 2015, vol.11, n.3, pp.177-181. ISSN 1646-706X.

Renal allograft anastomotic pseudoaneurysms (AP) are rare though associated with high rates of graft loss and mortality. Intrinsic transplantation mechanisms regarding active immunosuppression and/or chronic rejection increase susceptibility for their development, having a prognostic impact. We present a case report of successful surgical treatment of a 6 cm right iliac transplant patch pseudoaneurysm, diagnosed following an episode of acute obstructive renal insufficiency caused by AP ureteral compression. Treatment consisted, by a transperitoneal approach, in partial AP resection, antegrade termino-terminal renal artery re-implantation in the external iliac artery and right lower limb revascularization with extra-anatomical femoro-femoral crossover 8 mm PTFE bypass. There were no post-operative complications and renal function normalized to previous values.
