Graft Arterial Dissection and Thrombosis After Kidney Transplantation With Undiagnosed Fibromuscular Dysplasia From a Deceased Donor: Case Report and Review.

BACKGROUND: Fibromuscular dysplasia (FMD), a relatively frequent arterial deformity with an estimated prevalence of 2% to 6% has been sporadically reported during deceased donor kidney donations. Only 8 case reports are available in the previous literature. CASE PRESENTATION: In our work, implantation of 2 kidneys from the same deceased donor with macroscopically evident and later histologically confirmed FMD are presented, one of which ended up as acute arterial complication. Renal arteries were cut short to allow safe implantation, but arterial dissection and thrombosis led to graft loss in the early perioperative period in the latter case. CONCLUSIONS: Although resection of the arterial segments affected by FMD as a routine may allow implantation, macroscopically healthy-looking arteries might still be affected and thus carry elevated postoperative risk. The aim of our case report is to make proposal for an onsite diagnosis of FMD in case of clinical suspicion.
