Perioperative blood pressure control, delayed graft function, and acute rejection after renal transplantation.

Background: Blood pressure (BP) control immediately after renal transplantation is poorly understood, with patients experiencing both high and low BP levels. Donor kidneys lack the ability to autoregulate their blood flow, meaning high pressures are directly translated to the graft endothelium, whereas reduced perfusion may augment ischemic injury. We hypothesize that early BP control may therefore influence the early alloimmune response.

Segmental infarction with graft dysfunction: an emerging syndrome in renal transplantation?

Background: Segmental allograft infarction is a poorly characterized complication following renal transplantation. The present study was undertaken with the goal of defining the incidence, clinical characteristics, pathogenesis, and prognosis of this entity.

Methods: A retrospective study was performed, reviewing the renal scans performed on all renal transplant recipients at our institution, from January 1997 to January 2000.
