Spontaneous regression of renal transplant artery stenosis: a new case.

Stenosis of the renal graft artery is a relatively common complication in renal transplantation. Therapy consists of either transluminal angioplasty or surgical correction. Nevertheless some untreated cases show good spontaneous evolution. We describe a well-documented case of graft artery stenosis causing severe hypertension with declining renal function which experienced spontaneous resolution.
