Brief summary

Stenosis of the renal graft arteries occurs in 1 to 26% of cases and can damage the graft. Endovascular treatment is first-line treatment. The main objective of this study is to identify the predictive factors of failure of peri-anastomotic.

Detailed description

The aim of this study was to evaluate the post-operative outcomes following endovascular treatment of TRAS (Transplant Renal Artery Stenosis). This retrospective, monocentric study included patients with peri-anastomotic stenosis of the renal graft from 2000 to 2017. The stenosis is defined by a reduction of at least 50% of the arterial diameter during arteriography. Technical success was defined as residual stenosis less than 30% of the arterial diameter after the procedure.

Interventions

PROCEDUREAngioplasty for Transplant Renal Artery Stenosis (TRAS)

The angioplasty is an endovascular treatment for artery stenosis, which could be associated with stenting or not.
